Shooting 4 nrl hunter matches this year. Shot a 280 AI last year but decided to shoot a bergara 6.5 creed suppressed in a mdt hnt 26 chassis this year 11.99 lbs. Shooting 140 grain bullets with stabal 385,000 power factor. Hope to see you at a match and good luck.
It's NRL hunter and they allow up to a 16lb rifle, completely defeats the series. Anyone who hunts with a 16 lb rifle drives right up to their stand and sits. Not 1 of the guys competing in open heavy actually hunts with their setup. All I do with mine is take off the muzzle break and put on my suppressor, otherwise I go from competition to deer hunting with the same rig. There is enough leagues that allow heavy rifles not sure why nrl hunter had to do it.
Seems like a 10lb limit would be more reasonable, right?
Shoot light division. 16lbs comes from Idaho weight limits. Brady from Gohunt hunts with a 16 pound rifle
Killed 3 elk with the heavy open gun I used at hunter matches. Backpack off the road type stuff. Maybe get out and shoot stop bitching it's better for ya
My only rifle - with which I have now only hunted, is a 7kg (14-15lbs) .308.. I do stand hunt, but I prefer Walk+Stalk - I just have to hope there is a good Tree or Termite Hill within 200m of them..
Hoping to start doing some matches next year
@@marcmoore4115 what about a solid tripod I run 2 vets and rrs and shoot off them 75% of the time
I'm not an expert reloader but I had always thought that if a guy could get a slow load built with cool burning powder in 6.5 PRC he could get the barrel life and lower recoil when it comes to matches then use a faster load for hunting
I want to get involved in NRL, I am wanting to go an unconventional route since I would actually use a real hunting rifle and run a Sako S20 in 270 Winchester in the Factory class.
I just shot a NRL Hunter match in Great falls with a 6.5 PRC with a power factor of 462802. I cleaned a few of the stages as did others and I was top shooter on the stage because of the PF. Now, the PRC is not an ideal NRL caliber because of recoil, but its what I have and shoot and have supplies for. Shooting 153.5 bergers @ 3015.
I just shot the defiance antisocial. Myself as a shooter didn’t perform as well as I should have. But being my first one I had a blast. I shot in light open with my 10lb 9oz 7 saum. Hand loaded of course. Had an absolute blast.
I have to read more up on the competition as far as scheduling. But I’d love to shoot a .308 or 300 WSM! In my factor Savage 10 or a Browning if I can find one chambered in 300 WSM.
I realize 30 cal will probably produce a lot of recoil relative to the required power factor. Very interesting!
Thanks,
Isaac
I don't comment enough on this channel, so here it is.
Have you guys done a video on that NRL rifle? We’d love to see how you build that one up!
Would have loved to see you guys use a 25 creedmoor and some 131 grain black jack bullets.
The guy that won the ANTI Social NRL in Great falls ran a 25 creed. Not sure of bullet weight.
It’s all about the U 🙌🏼
Thank you for sharing your research
Great job, guys!
I don't know what other weight you might be required to carry, so I'm thinking a much lighter rifle with a better brake... Good and interesting info though. Good luck Travis!
NRL Hunter also has a max 3200 fps rule. So that means you have to have a 120 gr projectile or larger. So pretty much 25 caliber and up.
Power factor is interesting. Looks like they made a cut off at 6.5mm calibers
It does seem like that's what they tried, but I just checked, According To Nosler data, a .25-06 with a 24" Barrel can push a 125 @ 3150fps with spicy loads. If you can get it to 3200fps, it's at a PF of 384 000.. the .257 Weathery Mag can push a 125 @ 3400+, meaning it gets well over 400 000.... but .25 cal is unfortunately not available enough to make it worth it imo.
6.5x47 Lapua it is :)
@@marcmoore4115 yes, there are a few less common cartridges that make the cut.
i think it has to do with ethical hunting, making sure the animal is killed.
In USPSA pistol this is an issue. There are Power Factor requirements there as well because someone shooting super low recoil 9mm loads will naturally have the advantage.
I’m a loyalist to your channel and enjoy the vast majority of your content but, can’t picture you as a fan of electronic music (intro music). I’m a dinosaur so probably over my head. Keep up the great content!
Those speeds seem slow, I've always been over 2800 with 140 ELDm on four different barrels without going over 42 grains of H4350. Had 147's over 2800 using under 43 grains.
The power factor exemption for factory sealed ammo is limited. Must be 6.5mm and 130gr or above. See Rule 3.1.
Not familiar with N555, but have burned some H4350 and 6.5 StaBall in a few different chamberings including 6.5 CM. I'm curious how you came on those charge weights with both powders. Using Hornady data, you're 2 gr over max with your H4350 loads and 147gr ELDs, while being more than 1 gr under max for Staball and the same bullet. Similar situation for the 140gr, except you're only 1 gr over max for H4350, but still more than 1 gr under max for Staball. Wondering if you tried higher loads in StaBall? In my experience with a variety of bullet weights, it likes top loads.
@Travis Fox Interesting, you've certainly got to read the signs and load to your individual rifle. I wound up around 43.6gr StaBall under 143gr in Starline brass, didn't see pressure until around 44gr. I'm running 140gr Gold Dots a little higher, and in lower capacity Peterson brass (51.7gr measured capacity vs 53gr for H and S). The other thing I've noticed with StaBall is that it seems to be more sensitive to humidity than some other powders, I dried out a batch and saw pressure spike pretty significantly, brought it back to ~50% rh and it started acting right again. So if you're in a dry area, maybe that could contribute to some of the difference.
Primer choice can also change the velocity.
Good luck Travis. You better show good! 😂
They should also chronograph the factory ammo at the matches
6.5 cm Tikka action KRG bravo Leopold mk5 ckye pod single pull. Lapua brass h4350 cci450 berger 153.5 at 2700 gave me a power factor of like 414.000 ish. Last year I ran a 130 Norma golden target at 2950 with rl16 because that's all I had.
gavin.... kinda suprised you didn't catch the easy, very accurate solution, with less recoil then any you mentioned above...
Great info, thanks.
Man I complain about a 10 pound rifle when I'm hunting. I can't imagine hunting with a 16lb rifle. My 270 with scope, sling, and 5 rounds in the mag is right around 9 lbs, and I wish it was lighter
My 6.5CM Savage is 8lbs plus the scope. I don't even like to add the bipod for a trip to the range. I'd rather use sandbags.
Tikka 300 winmag 230 atip 2800 fps 644,000 PF. velocity maybe more depending how warm i can load
Will you be able to use a moderator
Didn't want to try and make the 25 Creedmoor work for this?
Why didn’t you push staBall more? Hornady reloading manual has the grains higher then what you guys shot.
What about the factory "reduced recoil" ammo? Is that legal for use in NRL Hunter competition?
I would imagine by now the 25 creed would be the go to round. 135gr berger vld or hornady 134gr eld match at 2900fps or a lttle higher.
I think it sucks that there is a weight penalty
if you can win a tie with a higher power factor, they should just enforce a maximum ratio of weight to power, sliding scale
more power allowing more weight otherwise, is this really Hunter?
sometimes you need a win mag or a 300 prc and you're not going to take a light rifle to make it work
Great video had no education on power factor. Bill O
I have a 16 lb 6.5 Creedmoor that I hunt with and love it ..... but I really want to learn how to reload for all of my rifles and pistols because I have a lot of brass that is just setting .......
Shooting PRS with 6.5 PRC, Bergara HMR,Hornady eld-m 147 gr, 2975 fps, PF 437.325 🔨🔨🔨💣💣
💪💪💪
Good channel bro
So you're saying I need to buy factory 224 valkyrie?
Great video. Do they trust you at the matches or will they run your load over a chronograph if you handload, especially if there is a tie? Also, what if someone handloads but doesn’t have a chronograph? I realize they can estimate the velocity from books and software, but they can’t be sure exactly what the muzzle velocity is for their particular rifle.
its ran over a chronograh for everyone who is in serious competition before the match
How do they verify the bullet weight?
16 lb rifle is for PRS/NRL guys to shoot a comp gun and not feel left out of the sport.
If I were competing, I'd use my own rifle and say (Expletive Deleted) the equipment race. I built mine with a 03-A3 barreled action fitted to a Fajan stock. Chambered in. .30-06. I doubt that I would need 220 grain bear loads to comfortably meet your power factor. I don't know what your course of fire looks like or at what range you'd be shooting at. You should have included this information. Perhaps handloads duplicating MILSURP M2 ball might be better if some shots are taken at 500 yards. You failed to mention if full patch bullets are okay or if you require softpoints.
Where do these matches take place? As an Army veteran, I am interested in anything that involves shooting.
@Andy Breglia:
Forgot to ask, how about MILSURP factory cartridges?
M2 spec ball comes in with a power factor of 420000 so it easily exceeds what is needed. It would be cool to see someone run something unique like that, although personally I'd load up some 175 grain SMKs for competition. That bullet at a mild 2650fps actually has a higher power factor than the M2 load and will be very easy on both your old rifle and your shoulder, as well as giving you a much better BC
Rifles shall be any caliber between 223 Remington to 300 Winchester Magnum and not
to exceed 3200 FPS
Average target distance is listed as 450 yards but it will vary from one match to another. 100-1000 yards
The StaBall loads listed seem to be contrary to physics, in that, with the exact same powder charge, and 7grs heavier projectile, it achieves 40 fps greater velocity.
While 40 fps and 7 grs are not in themselves huge differences, in this type of comparison, they are, and not only that, the difference is in the wrong direction, so there has to be another factor not listed.
The friction between the different projectiles, if the same diameter, couldn’t produce this, and would have to be well over .001” greater with the 140 gr projectile and easily noticeable. Was the temperature during these tests enough different to cause this? Is the projectile length with the 147 gr example enough to decrease internal volume and increase cartridge pressure?
Whatever the cause, it’s significant, because both increased mass and increased velocity increase inertia that must be overcome.
the higher grain bullet is heavier and larger, specifically length. the overall cartridge length stays the same (magazine and chamber parameters) so the lager bullet is set deeper into the brass, compressing the space the powder burns in, causing more gas to push the bullet.
@@RangerCaptain11A That was my second guess. I just wasn’t sure if the increase in burn efficiency would be enough to bump the bmep that much.
Thanks
Who hunts with a 16 lb rifle?
I do sometimes
Tradeoffs, I guess.
But 16? That's a little much for anything I would call hunting
@@bigald9560 dont get me wrong it's a chore and you have to condition for it lol but i like to have it on certain hunts.
That’s nearly the same weight as my old M249 and I wouldn’t consider that light.
@@ntsnow2000 lol is it a 6.5 creedmoor?
good luck
I really support a hunting class type shooting decipline, have been competing in one for years here in Namibia. Just don't agree that a 90gn 243 round will not be making a hunting power factor when it's widely used in real world hunting.
no matter what the class,reloads will out perform factory specs ammo and practice is a must for any class you shoot...Rifleman34...long live the reloader.....
Question.. with me being suck a 300 win mag fan and yes I k own about the Weatherby and the PRC rounds but has anyone seen,shot,built or have a 300 win mag A,I ?? Have I missed it am I late to the show?
I quite honestly don't think that exists.. I very well could be wrong though, but I just don't see a reason why anyone would AI it, considering that it already is pretty close to what an AI version of it would be.
@Marc Moore look at the 280 Rem... the case on the 280 AI is VERY different. The angle of the shoulder one of the biggest differences. The performance is s real nice step up. I don't have the tools or the knowledge to create such a idea. Was hoping I am not the only one who was thinking like that.
Still drooling at the mouth for the progressive press shootout😃
We are trying to publish on Friday
Can we get a year in that comment? Lol jk I'm excited too.
Its been hyped more than Top gun 2. " I feel the need, the need to reload.
10 pound 223 with optic 70gr 3100-3150
Nowhere near power factor
It’s supposed to mimic hunting yet, you build a PRS gun??it defeats the whole purpose and turns a sport that was meant for people that can’t afford to build these 10k guns to to be able to paticipate in a competition, and you turn it into a sport that you can’t compete unless you build one of these guns. Can’t believe people can ruin a sport so fast
Gavin, you have spamers making comments about winning product.
Thanks for letting me know- we are handling it, see: ua-cam.com/users/postUgkx9C-rN3NV1eYtPsw1C4IGZNg9XsFZtGqk
When’s the progressive press shootout going to premiere?
We are hoping to publish this coming Friday
If I understand the math, it is impossible to handload 6mm and smaller diameter bullets while meeting the power factor. But, I can take a factory box of 103 grain 6 ARC bullets and shoot them. #strange.
The smart guys are probably shooting factory ammo and adjusting the seating depth lol 😆
@@clapton924 You mean the cheating guys,
Power factor is a NO GO for me. A nice HUGE number that someone pulled out of their ass. Probably the same people that think no one should be allowed to hunt with anything less than a 6.5 creedmoor. Basically it locks you into a 6.5mm round as a minimum size to start. Screw that!
It's also interesting how many of these gun-tuber channel/infomercials seem to be able to get powder whenever they need it while the rest of us have to wait and fight over the scraps at PREMIUM prices.
Come hunting in New Zealand for a week & you wont be toting a 16lb rifle for very long!! Unless you are the lazy kind, and don't hike in to your hunting block.
Please stop saying grain weight. It is the same as asking how many pound weight something is. Grains are a unit of weight. Adding the word weight is redundant and not even english.
So basically, NRL hunter is explicitly designed to exclude 6mm shooters.
yep 100%
That and design a new “race gun” that costs just as much if not more then a prs gun
