  • One of those very important variables in shooting performance and accuracy that so many of us take for granted or never think to check - the twist rate of the barrel in our rifle. What is the twist rate, why is it so important to consider, how do different twist rates affect our projectiles and how can you figure out which twist rate is best for your application? Ryan Muckenhirn joins Jimmy and Mark to drop some knowledge on the subject!

    The barrel twist vs barrel length issue is mainly related to muzzle velocity. The twist rate formulas ask for muzzle velocity bullet weight and shape. This is because what matters for stability is the revolutions-per-minute. To get this, you need the correct combination of twist rate and velocity as the bullet reaches the end of the barrel. A lower velocity needs a higher twist rate to get the proper RPM's. With a 223 Rem, for example, the speed of a bullet at the end of an 8" barrel will be lower than the speed of the bullet at the end of a 20" barrel. To get the same RPM's the twist rate of the short barrel will need to be faster than the long one.

    Tighter twist rates also increase surface speed, heat from friction, heat from pressure, barrel wear from increased friction on hotter metals, copper fouling, bullet jacket damage etc.

  • @Jeff_Seely
    @Jeff_Seely 2 роки тому +2

    Yes. Increased twist rate if it is aggressive it could potentially cause overpressure. So if you were shooting a heavier bullet at an aggressive twist rate, you're going to want to reload with the slower burn rate powder. And this is especially true if you are running a long barrel.

  • @danielback3236

    Good talk guys, I have an older 243 that shoots 100gr hunting bullets great. I have recently started coyote hunting and experimenting with lighter bullets. I have been trying to learn about it but everyone seems to go to heavier long range but I’m trying the other direction. Either way this is great info. Just another reason my 1:9.25twist 700 is very versatile.

    I've shot my 7 TCU Contender with 14 inch barrel to 500 yards with a Hornady 154 gr. SST going 1900 fps. Hit 6 of 10 rams with enough energy to knock the 50 lb. rams over. Barrel length only relates to the velocity part of the stabilization part of the formula. Use the Berger stability calculator to determine twist rate needed for stabilization.

  • @Brett235

    I'm not a professional by any stretch of the imagination but I have done quite a bit of shooting, and what I have found is with 55 grain bullets a 1/7 or 1/8 are perfect at 100 yards, for 5.56. My Grendel has a 1/7 twist rate heavy stainless barrel and it holds a .5" groups at 100 yards with wolf fmj ammo out of a 16" barrel. Both of my 5.56 barrels are also 16".

    I've noticed that since I was a youth hunter and the fact that the AR platform has become so popular, the 223 deer hunting rifles of my youth have seemed to become less available. I started with a 243 but I knew quite a few of my friends that were using 223 rifles when we were 12 or so. Seems like now that cartridge is viewed as a varmint cartridge and is way less popular for deer. Conversation aside, as to whether or not someone should use that small of a cartridge for deer, it has been done for decades, but now seems harder to find a deer hunting twist rate for a 223 bolt gun.

    Hello Guys. I think that you guys are absolutely awesome and very knowledgeable. So, don't take this the wrong way. I have asked this same question to other esteemed ballistic scholars such as Phil Cashin and Ron Gervase. I honestly question that anyone has ever really experienced or seen a twist rate that is so extreme that it causes a projectile to come apart. I think that the handful of times that people think that have seen it, they actually saw something else (i.e. your gun was terrible aligned, gas coming from a suppressor, etc.). I would challenge this. We can find countless videos online of ballistic gel tests. Why haven't we ever seen a video where someone demonstrated this twist rate issue (i.e. .308 shot from a 1:5 barrel) to prove the point. 8.6 Blackout feels like an example of how you can twist a huge bullet really fast. Please know that I am putting this out here so that someone will prove or disprove this theory once and for all.

    I have an older mini 14 with a 1:7 twist. Ruger now makes barrels with a 1:9 twist. I suspect they did this to reduce the dispersion when shooting a 55 grain bullet. I’ve been thinking about what I need to shoot if I want to reduce dispersion by hopefully achieving the same rate of bullet spin. If I assume a 55 grain bullet has a muzzle velocity of 3250 ft/sec., 3250/9x7 would give me a desired muzzle velocity of 2528 ft/sec. A 77 grain bullet has a published muzzle velocity of around 2800 ft/sec. I think I’m going to see how 77 grain ammunition works. Since the bullet is a little longer, my 2528 ft/sec should be a little too slow.

    I can add a little bit of info to bullets coming apart from what ive seen with 223's. I have experience with bullet failures in f class with the 223. Shooting the 90 vld's after about 600 rounds on a barrel is when the issue starts usually. It appears that fire cracking in the throat is one of the main contributors. Keeping carbon out of the barrel seems to prolong bullet life. So, maybe it is more of a carbon building up in the fire cracking than it is the fire cracking itself. Barrel temperature seems to exasperate the issue also. In the cooler spring and fall temperatures it is has been less of a problem making it through a 60 round match.
    I would guess twist rate did play a part in bullets coming apart in ryan muckenhirn's situation, along with "damage" to the bullet from fire cracking in the throat area and barrel heat. I believe that a bullet being spun so fast is the final straw. Looking at bullet rpm's you can really see the difference.

    This is great information. I live in Comi CA and pistols are not allowed so I’m considering a 13.7 pin and weld pistol length gas system AR with a 1/7 twist and a nox keymo flash hider. I’m primarily going to run supers and occasionally some subs and using for home defense and at the range and some hunting. Will the 1/7 twist run reliably for both SuperSonic and subs? And for what I’m doing is the 1/7 the best choice for my situation? The manufacturer suggested a 1/6 twist but I was skeptical on that and I don’t want over stabilization.

    Rifling type is a big contributor to bullets exploding. You can take two barrels same twist with two different riflings and over spin the bullet. Possibly get two different results. Like some rifling deform the bullets less. So it doesn’t deform the thin jacket so it holds together better.

    Progressive Rifling Twist was tried in Italian Military Rifles circa WW2 era, and apparently wasn't very successful. Thinking about it, it would likely apply unwelcome extra stresses on a bullet when it's already in a pretty stressed state? Modern materials though, may provide opportunities for it to be beneficial?

  • @chadillac95
    @chadillac95 2 роки тому +1

    So would you say that the faster the twist rate, the slower the muzzle velocity? Say you shot a 180gr 300 wm out of a 1:10, you should get muzzle velocity right around 2900-3000 fps. If you dropped the twist rate to a 1:9, would your muzzle velocity also drop to let's say 2750-2850 fps because the energy has transferred from forward propulsion to rotational force?

  • @geraldbrunckhorst8291
    @geraldbrunckhorst8291 11 місяців тому

    So I’ve purchased some 195gr 30 cal long range bullets to reload for my stainless Ruger .30-06. The gun was built about 1994 so I’m assuming about a 1:10 twist rate. I’ve reloaded many 150 (special) ,165, 180, and 210 (special) grain bullets for this gun and a 1970 Remington .30-06. I’m also assuming the Rem has a 1;10 twist. I have sweet formulas for those loads yet this bullet is so long I feel I’ll either be seating the bullet to shallow thus running to far forward (to deep) in the action or l’ll seat it so I end up compressing the actual powder. The 210gr is used in heavy brush during close range elk/moose/bear ”tracking shots” (lighter powder charge) whereas this 195 grain LR bullet will be for the opposite type shots. At this point it’s intended to be a .30 cal experiment. Building and dialing in the load will be interesting yet I wonder; based on your twist rate talk, am I asking for a nightmare of tumbling or inverted bullets? Will that bullet seating be a really critical element to this experiment? What other factors may become critical that I may need to consider? I’ve had exceptional accuracy and knockdown power out to 400 yards with a Barnes 180gr lead soft point. This has led me in the direction of looking at LR bullets and capabilities. I don’t favor long shots over spot and stalk. When I have opportunities I favor the knock down (usually less than 200 yards on elk -as little as 18 once- and 275 yards on deer). As I age all and new opportunities need consideration.

    It took me so long to work out why my 55grain soft points in my .243 wouldn’t hit anything from about 50m onwards.. at 20m I was only getting a couple hits.. turns out the 1:7 twist was tearing the jacket off.. 😅

  • @Jeff_Seely
    @Jeff_Seely 2 роки тому

    Thank you for the video. I found it educational. But what I have been told by barrel manufacturers is it's not an issue of weight, it's an issue of length that decides the twist rate you want. And just because a bullet is longer doesn't mean it's heavier. I have shorter spitzer bullets that weight 40 grains more then my berger vlds. But longer bullets require more twist per distance it travels.

  • @michaelwalters8074
    @michaelwalters8074 3 роки тому +1

    Great discussion. If reloading, by decreasing the velocity compensate for stabilization?

    • @wisewhiterabbit
      @wisewhiterabbit 3 роки тому

      not always. entirely depends on the bullet you use, the powder and primer you use and the barrel you intend to launch them out of. when you hand load, you (rule of thumb) do 10 cartridges, at each .03 grain incremental powder charge. at some point, if you dont see pressure signs first, you will see groups open up from going too fast. its theoretical mostly, but some of that is the bullet being pushed too fast and some of it is the barrel harmonics. in slow motion you can actually see the barrel vibrate and "whip" around as the bullet gets launched. its microscopic in movent with a thicker barrel, but very noticeable in a thinner barrel. so, short answer yes, long answer, depends.

    Lighter bullet materials require a longer bullet, all other things being equal. That’s why Sierra told me a .308 with 1:12 twist was fine up to 190 grains but Barnes (all copper) said 162 grains was their upper limit.
    Also note that the 8.6 Blackout is spun 1:3. Yikes!

    What twist rate or barrel would I need to make a 10/22 or 22LR Precision Rifle?

  • @steelrarebit7387

    A M4 Carbine standard ammo is 62 grain M855 ball ammo. The twist rate of the M4 is 1-in-7. Standard barrel length of the M4 is 14.5 inches.

    I would think the rate the bullet was actually spinning would depend on only twist rate and muzzle velocity. Because longer barrels typically increase muzzle velocity, barrel length would affect bullet spin speed.

    I bought my son a 6.5cm mossberg patriot short barrel. And the heavy weight 143 gn bullets wouldn’t shoot. They would either miss completely or a few hits I had were key holed. The mid weight bullets shot just fine.

    I think it comes down to what the rifle likes.
    I have a 1:7, a 1:8 and a 1:9 barrels for my .A/R. The 1:7 is pretty good for 69-77 gr bullets. The 1:8 I use for 65-77 gr. It’s a tack driver with 65 gr. Also really good with 69 gr. Opens up some with 77 gr.. I use the 1:9 for varmit loads from 40-55 gr.
    Haven’t found one that is good with 62 gr. My rifle just does not like 62 gr pills. I just stay with my 1:8 now. Got to be to big of a hassle to change out barrels.

    260 Remington is a wonderful cartridge, 125gr Nosler Partition.

    Can barrel twist rates be overcome by velocity? I've got a 308 and a 300 win mag the 300 win mag has the powder to push a 200 grain bullet around the same velocity as the 308 can push let's say 175 grain bullet since it's leaving the barrel faster does that compensate for a slower twist in the barrel. My 300 win mag is a one in 10

      Partially yes, more velocity increases rpm's.

    So given that very light bullets flying apart when overtwisted is actually uncommon, would it be more common for these bullets (which already probably have pretty poor BC) to just deform a little bit totally messing up their ballistics?

    • @indiedavecomix3882

      That's a very good question I'd like to hear an answer to.

    • @kirkmartin2223
      @kirkmartin2223 2 роки тому

      Quick answer.....yes. So looking at something like a 204 ruger or 22-250 with light jacketed light weight bullet with the BC of a ping-pong ball, one little imperfection on the bullet "can" effect group size. Spinning a bullet apart these days isn't as uncommon as you might think. Load a 40-50gr varmint bullet in a 224 valkyrie with a 1:6.5tw barrel and watch lol. Also I've seen where a bullet will stabilize in Denver but not in Houston......elevation has some play on things also.

  • @joesabedra8792

    Looking at twist rate I found something that Hornady needs to add to its specs on bullets. The length of the bullet. since caliber, weight and length of bullet are all of the things needed to define the proper twist rate that data should be published.

  • @davidgendron1953

    So I use 30-06 for all my hunting(Yukon) and I use 165 gr for caribou and sheep but use 200 gr (Norma Oryx) for moose and bison.... out of a Ruger no1 rsi and a M77 mkII and a Belgium made BAR.... what should I expect?

    • @davidmunro3910
      @davidmunro3910 3 роки тому

      Just my opinion. I'm curious as to why?. But I've been told by good people that 30-06 will stabilize anything from 120ish stuff up to 200 and220 gr moose loads. I'm sure Ryan can tell us. But old grandad seems to be a magic caliber. I myself have shot 150 180 and 220 stuff bang on at 200 yards.

  • @russellkeeling9712
    @russellkeeling9712 3 роки тому

    You can see the bullet explode if you use a 110 grain plinker bullet in a 30-06 and load it to the max. for an 06. The light weight of the bullet allows much more powder so velocity can be very high thus high rpm the bullet was not built for. It puffs into a greyish burst shortly out of the barrel. I don't know if it is bad for the firearm though.

    Remington spins them slower than other manufacturers. But it doesn't prevent 1/2 moa groups.
