Finally someone who knows what point blank range means......some think its inches from your muzzle ( TV News, Movies, ). You gave a great explanation on the how to.
Yup....exactly know what you mean when PBR is portrayed like that. Irks the heck out of me when I'm the only one in the room that knows its total misconception of what PBR actually is.
I'm one of those people who thought it was distance from the muzzle. Interesting.
Point Blank Range is one of the most abused terms thrown around and abused by the media. Some many of my shooting buds will swear red faced that bullets will fly and rise.
Since when do tv news, movies get anything right?
sir, I will say i have looked all over the internet for some form of explanation that I could understand thank you thank a lot
ahhhh it's all over the internet-LMAO. Now I know why these type of videos are made-LOL I guess your mommy had to spoon feed you everything-lol

Your watching this video too fucking idiot
I had a 270 custom bolt that liked Federal Premium 150 gr. SP (quarter size group 3/4 inch @ 100 yds) I was point blank out to 235 yards. The rifle never missed. What this gentleman is describing is spot on.
Excellent explanation of what PBR actually is. A previous commenter also mentioned how it's mis-portrayed in hollywood and the sadly the news. Good stuff.
Consider the 36 yard zero for the 55 gr round. Keeps you inside the 6” pipe to 300 with a 16” barrel.
Thank you! This is why I like my 22-250, 6.5x55mm and 25-06 rifles and ammo, all flat shooters.
Thanks, good info!! so assuming a 10 inch target (average size deer kill zone) you could reasonably stretch the M>P>B>R to 350 to 400 on most common deer calibers with a 200 to 225 yard zero!! so that your never more than 5 inch's above or below line of sight and aim mid point shoulder to brisket.
You need to add in the normal variability in you groups at that distance, so if the kill zone is 10 inch and your practical group is 5 inch at 400yards,(In the field conditions with reasonable margin for unknowns in windage, barrel temp and air conditions. 5" at 400 is still a tight 1.25MOA) then your maximum point blank target should be no more than 4.5 inch height(height is a more accurate term here than diameter) or 2.25" up or down from center. 4.5+5+0.5=10" top to bottom or 2.25+2.5+0.25=5" from center.
Say you are mathematically at the top or bottom edge of the PBR, half of your group will be in your favor to the inside and half will be outside, so an extra 2.5" from center(5"total) must be added for a 5" group, and the 0.25" from center is just an extra margin to compensate for optimistic estimates and errors in baseline measurements.
Since an ideal PBR at 400yds with most rifles will be larger than 4.5" total height and 1.25moa is pretty optimistic, the answer is no you can't stretch it to 400yds.
That is total target height minus group diameter(at that range) minus any extra margin you want equals required PBR height. Divide this in half for distance from center.
The allowable PBR height will be larger at closer ranges because the same MOA will result in smaller groups and have lesser effects from uncertainty in variables. So basically you do the calculation (target height minus group size minus margin=PBR height) for every 50 yards until you hit a PBR height that matches your rifle&ammo ballistic capability.
site close range for long range, i have used this method for decades a lot for pump air rifles since i like to switch pumps and distances, i simply zero in and my point of impact at distance, then at 10 feet i fire a shot aiming at a 1/4 inch dot, then i keep the paper or measure how far down shot went down from my 1/4 inch dot, then if i switch site in i can quicky go back to previous dot and copy hole that was below my 1/4 inch dot. i got a clever little trajectory set up for my browning buckmark .177 pistol, i got a video showing how to site in to hit a fly at 5 feet and still have it sited in for its maximum flatest trajectory to hit 1 1/2 inch orange dots as far as it will let me with out sites becoming loose from over adjustment. people forget to chose a target size because target size is important and also what maximum range you are willing to settle for to hit the same size targets every time at multiple intervals.
I use a cap off a 2 liter drink bottle and sight my rifles in at 25 yards if I can hit that at 25 i can take any thing from deer to rabbit if I have a clear line of sight to 100 that is about as far as you can see something in the woods of east Tennessee
Raising the scope off the bore increase's the Point Blank Range. 1.5" is the norm established a long time ago because scopes and rings were not made for much more. But not today. Here's a simple formula on where to shoot at 100 yards for a 200 yards zero. Example: scope is 1.80 inches high. Formula: 1.80 - 1.50 = .30. Divide the difference, which is .30 by 2. You get .15.
If manual says to shoot 1.5 inches at 100 to be on at 200, then to adjust for scope height and subtract the .15. It now becomes 1.35 inches high at 100 to be on at 200, which also extends the drop beyond the 200. This adds about 20 yards or more to your point blank. The higher the scope, the longer the point blank.
I run across people all the time who insist the lower the scope, the better it is for accuracy (mostly old timers). Nonsense, you can only go so high before you can't even see through a scope. Too low makes you cramp your neck and head. Too high makes you stretching your neck and head. Adjust the scope for where it suits you best for eye relief, angle of you head, and visibility. Don't pay attention to the height until you're ready to zero. Then do the calculations using a ballistics calculator, and zero it accordingly.
You can determine your own point blank. For example I use 6 inches most of the time for deer, where the path goes no higher than 3 inches, and no lower than 3 inches to determine my best performance range without having to compensate for distance. On smaller game, I use a 4 inch point blank, or less.
Great info, explained correctly!
Really?
So the bullet can rise after it leaves the muzzle?
The reason I ask is because of gravity.
Seriously though I am almost positive the bullet doesn't ever rise,only drops.
What am I missing here?
Thank you for any effort attempting to teach me.
@Klevee. The bullet rises above line of sight because the rifle bore is angled up relative to the line of sight. The bullet does not rise above the bore line after leaving the muzzle.
If one doesn't like being 3 inches high at midrange, use a smaller diameter pipe. The beauty of PBR is you don't need a fancy scope, and it separates the wheat from the chaff when comparing cartridges. PBR is so simple, one doesn't need any fancy gadgets nor does he have to calculate much.
A good range finder that will read accurately off of soft targets (animals, safebrush, etc.) out to 400 yards is all a guy needs once your scope is properly zeroed in for MaxPBR. Or, you can use the mil dots /moa dots in your scope's reticle to quickly and "reasonably estimate" the range to target if you know about how big the target is compared to the spread between dots at 100 yards.
Excellent demostration an presentation!
Very good explanation, thank you!
Not really. It could have been explained so much better. LMAO
@@vincef5832
And I seriously doubt you can do any better? 🖕🏽
Good info. Even for us old hands Good refresher course. Explains exactly 👌🏼
I've always used the term point of aim, point of impact to describe the term you use as Point Blank Range and point blank range meaning within about 7 yards. I stand corrected.
Very informative. I find these calculations very useful.
I was thinking about this exact concept recently. I'm glad to find out it actually has a name.
In military marksmanship, this is known as "battlesight zero".
you just explained in 3min what others failed to do in 30 min;-)
Thanks!
two and a half inches high at 100 is the old saying, looks like the old timers knew their shit
Like a broken clock being "on time" twice a day, a trajectory is correct twice a shot.
Not necessarily broken. You only hit the x-ring twice, but stay in the black from zero to 225 yards. Vertically. Accounting for wind drift and trigger control is still a matter of skill.
@@bgallaher77 skill helps but dumb luck can never be under estamated lol
@@bgallaher77 ringo isn't talking about the PBR height extremes. The bullet generally passes through the exact line of sight twice with scopes that are mounted above the barrel. The only exception is when the line of sight is exactly tangent to the bullet arc, which only happens with a zeroing range that results in a bullet rise exactly equal to the height of the scope line of sight above the muzzle. Any shorter zeroing range will have the bullet climbing through the reticle(and eventually falling back through if it doesn't hit anything), and any longer range will have the bullet falling through the reticle(after first climbing through).
Bob Milek would be proud !
Thank for very useful information.
Great info. I just use a 200 yard zero.
What about on a . 22?
Guess every gun, barrel,caliber and scope and rings are different.
I set up my Tikka t3x 270 with zero at 100 yards and it's still good at 50 yards. I drop down one black dot at 200 and 1and half at 300, with good results.
Almost all of my shots are between 60 and 125 yards and have no problems.
I feel comfortable out to 80 yards for side head shots.
I hunt for meat and don't like wasting shoulder meat, would rather pass on a whitetail than waste the meat.
Got a like and subscription from me, simplest explanation I've seen so far. Your video will be my first recommended viewing for anyone willing to learn hence forth.
I sight mine in at 33 yards. Shoot once, adjust windage and elevation X 3. That puts me really close at 100. You can fine tune after that.
The problem with this is that the shooting down a pipe idea is based on horizontal shots ONLY with the earths full gravitational force in play. But what happens when shooting uphill or downhill? The gravitational pull has a lower effect on trajectory and the projectile will LEAVE the pipe boundary at shorter distances.
Thanks this was easy to understand
I always zero my rifles at 1" high at 100 yards, which puts me about 1" low at 200 yards. All of my hunting shots are within this range, so it works perfectly for me.
Yeah every gun I own except my 300 is zeroed 1 1/2 inches high at 100 yards easy peasy.
Very well explained
Excellent example!
for anyone interested
m855 62gr from 14.5/16 inch barrel
40 yard near 250 yard far zero
MV 2907-2980
HOB 2.6 inches
highest point 3 inches 175 yards
Max PB on 8inch target is 4 inches low at 300
use the Hornady ballistic calculator with G7 drag coefficient and .151
I hope that helps anyone looking
Right on. I had an AR-15 a long time ago with the A2 configuration, and a scope mounted on top of that. It me a while to figure out that there was quite the arc with the scope that high above the barrel. All the ballistic calculators assume one inch sights above the bore axis, which I am pretty sure doesn't hold true in today's scope filled world, and definitely doesn't hold true on the AR platform.
Great video I'm going to figure this out and re-zero my 22 wmr bolt gun. Although I feel like I'm close with a 75 yard poa/poi.
I would guess your max muzzle vel to be about 2950 to 3000 maybe with a 16" carbine. You lose a lot of velocity with the shorter barrels, Figure 30 to 50 fps loss per inch. It is also very likely that those Winchester velocities are measured in the lab using pressure barrels of 24 inches, not the standard m16 barrel length of 20".
Depends on the cartridge also
my 30-06 is zero at 325 ...... just the way I have always done it with 30-06 .... oh yeah, my sightline is 2 1/2 inches above bore
@Buddy Chat I seldom if ever kill past 400 yards ..... 178 grain zero at 325 ..... holdunder 6" between 100 and 200 yards ..... 275 is 3" holdunder .... 400 is 10" hold over .... that's it....yup .... I shoot off of top of crosshair ..... further out and for windage I use the graduations on the crosshairs ..... I am an old man and that is old school but it does pretty well for me..... I still shoot old model 70
I saw a video where you can zero a 270win at 25yrd and it will be within kill zone of deer anywhere from 100 to 300 yrd. As it rises a few inches at 100 and levels off at 200 and at 300 it drops again.
Hi,
The video that you watched might have been how to bore site your scope to the barrel of your rifle.
These guys are talking about ballistics and where to shoot after you have bore sited your scope.
Hope that helped.
Hope I'm correct.
Peace
No, its called a 25yrd zero. It will keep you within the kill shot of a deer. From 100 to 300 yrds.
Good vid!
I zeroed my 30.06 24” barreled hunting rifle at 25 yard and my second zero is 270 to 280 yards with hornandy gmx 150gr 3080 fps I’m good too 325 yard in 6” circle its same as your 270 250 yard zero is your second zero your first is around 25 yards and is more easy too zero it 25 yd then 250 yd
Are you using a single setting or adjustable 🤷♂️
Im trying to zero a .300 win mag for 5” total target size, with the normal 1.5” scope elevation. What’s my MPBR?
Ps. Not a bot, please help
Great discussion!!
In military marksmanship parlance, this is called, "battlesight zero". There are several ways to achieve it due to simple geometric principles, but it is the same concept.
@Meh Right you are my friend! Ex sniper here. 89-93". Cheers!
So what distance is close range zero? 26 yards ive got zeroed for on my 270, 130 grains. Its from a website on point blank range.
Good job.
Thanks
What is your thoughts on 25 yard zero for 100 plus hunting range?
Usually I am not a fan of sighting in that close. Yes, the math/ballistics show that it can work. The propagation of error is what makes it tricky. Your range to target needs to be more exact than when sighting in at 25 vs 100 yards. One MOA is 1.04 inch at 100 yards, and rounding to 1 inch is good enough. 1 MOA at 25 yards is 0.26 inches. You have to be very precise if you are one quarter of an inch off at 25 yards, you are 4x off at 100, etc. So, it should work at 25 yards but bring a tape measure and be precise. Ahh, and you posted you would not be shooting past 100 yards. Kill zone on a deer is 10 inches wide and 18 inches tall when taking a broadside shot? The lungs alone are the size of a salad plate, with heart below and arteries and spine above. So, being off even a couple inches is fine in that scenario. My opinions. Oh, I usually sight in starting with a shot at 10-15 yards. Then a couple more at 50. Then final adjustments at 100. Sometimes I have to make larger than expected changes as I get further out.
Is good zero 25y zero for hunting loads
I do the same i zero my 30.06 at 25 yard , from 0 yard to 325 yard is less then a 4” group with Hornady 150grain gmx superformer bullet .
Use shooterscalculator.com
Big game hunting is the only reason to use max point blank range. Hitting 3 inches high or three inches low hunting deer will keep you in the vital zone .
great Supot behind greetings one Laras
Sir, .223 Remington is NOT the same as 5.56 NATO. While there are a few similarities, the pressures are quite different, hence, muzzle velocity is: it's right there on the box of ammo for each. The data you state is misleading.
So, where the rubber meets the road is the change in point blank range. What is the difference in point blank range? Is it a meaningful difference? Most people will be shooting a 556 using. 16” barreled carbine. Yes, you can get 18”, 20”, 24” as well. 223 is probably shot out of a sporting rifle with a 22” barrel. Is there really a meaningful difference after the bullet leaves the muzzle? Edit: published velocity is almost always from a 24” barrel.
Make your own video
What is the point blank range for M4A1 for a Standing/prone target? For AK74 rifle the range is 625/440 meters. The battle sights are 400 m.
It's all about the bullet data.
Remington 7 mag point blank range FOR AS U CAN SEE
So how far would a bullet fly FLAT out of a 308 if fired parallel to the ground, before the bullet would have a measaurable drop?
I'm trying to figure out, if this could in theory produce a bulls eye at say 100 yards and any closer distances with no mesaurable deviation (be it high or low)?
Well, gravitational acceleration is 32 ft per second squared. Bullet starts to drop immediately once it leave the barrel just as fast as if it fell of the end of the shooting bench. When the bullet has travelled a full second it will have fallen 16 feet.
@@bgallaher77
So basically the barrel is always slightly canted upwards, no matter what distance zero you are setting for?
So everytime the bullet exits a barrel on any gun, it always climbs upwards first and peaks half way between the barrel and the set zero, before descending towards the set zero...right?
Think of the football quarterback. If you are throwing a long pass, you have to lob the ball pretty high up. One, the scope is around 2” above the barrel. So, no matter what the barrel will have to be turned slightly up for the bore of the barrel to be pointed where the scope points. After all, you cannot aim a gun by looking down the barrel. The “zero” is where the Point of impact is the same as the line of sight. Typical I sight in for a 200 or 230 yard zero. That means I want the bullet to hit about 3” above my point of aim at 100 yards. Between the shooting bench and the target the bullet has been lobbed so that it travels over the point of aim and then hits the target. If it had not hit the target it would continue to travel on the arc and then start to fall. With a 200 yard zero the bullet would hit the point of aim on a target at 200 yards. Now, air drag dramatically slows the speed of the bullet, so the peak or the arc is somewhat closer to the target at 200 yards then the rifle.
@@bgallaher77
Thank you for the excellent explanation.
Would it be fair to say that with all things being equal, the arch of the typical 308 bullet would be less pronounced if zeroed at 100 yards as opposed to being zeroed at 300 yards?
I kind of like the analogy of shooting through a 6 inch pipe...so basically instead of shooting through a 6 inch pipe, the closer distance would be like shooting through say 3 inch pipe instead?
Absolutely. In the real world, there would be very little arc to about 125 yards if you sighted in at 100 yards. And, if you only plan to shoot targets with 150 yards or so then that is fine. Where I hunt it pretty wide open and a 200 to 300 yards shot is not uncommon. So, I use a 230 ish yard zero so that I do not have to guess at distance or worry about hold over.
Soooooo this isn't Battlefield if I am right
i hear most people with an AR-15 have 2.7 inches
Woooow
Not what therm means. Point blank means close enough that you don't need to aim/see the sights.
en.m.wikipedia.org/wiki/Point-blank_range
👍👍👍👍😎😎🇺🇸🇺🇸🇺🇸
a bullet does not go up nor rise. it only drops FYI great video though
Pretty sure the video covered this. The arc of the bullet causes it to rise above the line of sight because of its trajectory (like a football... which is thrown up and not perfectly horizontal). The video did not imply or state that the bullet has lift like an airplane wing.

@@bgallaher77 Probably because of 6:44 where you said it is rising.
I understand you meant rising in relation to your viewpoint through the scope though.
Why would you use a ballistic calculator for MPBR(and MRT)? Most small bores will be between 245 to 275 yards. LMAO Some of you internet guys make me laugh.
