Reasonable Expectations

"Puss" in boots!

Nah, too heavy for my fragile physique ……. I wear Nike Max Air LTD's! memtb

I try to keep all moa or under. It all depends on the rifle and bullets. I have some hammers I've been dialing in at 200 yards that are getting there.

I think most guys won't make it minute of pie plate with that recoil, it's an acquired taste!! I've shot a lot of heavy big stuff for fun and you learn to shoot it well, I have no different expectations than I would any other rifle as long as the shoulder held out.

Using Litz TOP gun theory - which is not a perfect thing but a general formula made from correlation regression of tested rifles precision. Not how I prefer to see the term theory used as a scientist myself but I digress..

Anyway.. there are rifles that will beat this. It's not a guarantee.

(FT LBS @Muzzle)/(weight(lb)/200

(5500?/9)/200 = 3 moa - 5 shots

60% of groups within 2.1 and 3.9 moa

95% of groups within 1.2 and 4.9 moa


Your rifle has got to be brutal to shoot repeatedly and with no variation. I've always been impressed by people that can actually shoot rifles like that repeatably

Using that formula……I'm start'n to feel a bit better! I may just have a 600 yard rifle!

Well, it's a 600 yard rifle, if I'm a 600 yard shooter …..that's the question! memtb

The possibility is there to shoot some nice small groups, but that much recoil is tiring. I have a 7 1/2 pound 33 nosler, no brake, a 225gr at 3050, that should be high 40's -50ish pounds of recoil. It's difficult to shoot small groups with a light gun and high recoil. I have shot some stellar groups, and it will normally hold 10 shots into 3" at 300y. But after 6-7 shots the recoil is tiring, you take a beating with fast recoil.
Its not out of the question to shoot some under 1/2 moa 5 shot groups, but thats gonna be tough with that much recoil.

I still shoot 1 1/4 oz slugs off bench at 1500fps. Great recoil training.! Boy do they knock the snot out of deer....and you.

Does rifle recoil factor in at all into your 1 moa or am I just a "puss"? memtb

" Can I get a price check in Isle 5 on Cat Litter Please....that's Isle 5".
My theory @memtb is recoil has no effect on the accuracy of the rifle...but can produce a dramatic negative effect on the shooter.
In my younger years with my 460 bee I was capable of shooting 3/4" - 1 1/4" three shot groups. Hadn't fired my bad boy for about 20 years so I took it out a few months ago....now....after double rotator cuff surgeries....that first shot was a banner dead nuts bullseye...the next 2....hmmmmm...let's just say that by the time the tears went away...I saw a beautiful 2.5" group. But to answer your question...
Hunting Rifle....and you stated 100 yards...3 moa would still get the job done on a heavy hitter! Just me

#51 - TOP Gun Theory - The Science of Accuracy

Theory of Precision for Guns or the TOP Gun Theory characterizes the precision potential of any rifle based on a few accessible variables.

thescienceofaccuracy.com

Worth listening to, documented deviation in rifle muzzle location before bullet exit that increases and gets more variable with increase in cartridge size

I highly doubt a light barreled 375 isn't full on noodling during the ignition/bullet movement event. That's setting aside recoil movement changing the point of aim because the whole system moves, which also happens (and why there's a push for flat bag riders)

Put simply the gun moves before the bullet exits. The more movement the harder it is to have consistency over large sample sizes, and the more things have to go perfect everytime.

What the heck are you shooting that makes 59 ft/lbs recoil and you want to use out to 600 yards? Why?

For "big game" elk, mule deer, bear, I stick with the 30-06, 375 H&H, 7mm Rem Mag. Even the heaviest 375 H&H loads only churn up about half of your 59 ft/lbs recoil...

I've shot 458 Win Mag, 450 Ackley and of course 50 BMG, but dang... Whatever you're shooting sure has some suds!

With hunting rifles I like the cold bore, and three shot group standards. Never needed a 10 - 20 shot group from a sporter rifle. Competition was different with 20 round strings of fire.

Cool subject and discussion!

Regards, Guy

It depends on the rifle weight... My 375 calculates to 55 ft-lbs recoil and over 21 fps recoil speed... It'll get your attention. She's around 8# scoped.
My 300wsm pistol only generates 42 ft-lbs recoil but 23 fps recoil speed,
Both are entirely manageable recoil wise.

A pick of my kid rocking the 375 the summer of '23...

I think I could shoot it. I shoot a 458 Lott.

That said, I think I could get to 1.5-2.5 MOA at 100 yards. I don't think I could get very good beyond 300 yards as it requires a lot of practice setting up rests, etc. Maybe 4 MOA at 600 yards. If you have a similar practice rifle in a shoot able caliber, maybe 3 MOA.

How many rounds can you shoot in a session prone, tripod or similar field positions before the tears start?

I'm a weakling, 6 rounds of 375 Ruger off the bench and my headache kicks in. That being said, I'm getting ready to chamber a 416 Taylor barrel. Guess I like an occasional beating.

There can be different standards. The shot that really matters for hunting generally is the first one, and ideally the only one. Right?

A barrel that is saving weight can't be a 26 inch MTU barrel. Often you're going to have a smaller profile barrel, so right away, you're going to have issues related to heat dissipation if you're shooting it like a PRS rifle. Groups will open up.

If you're carrying a bigger bore magnum, then recoil mitigation might be a problem for some.

Other than that, if fundamentals are there, and rifle is capable, it should shoot what it's going to shoot in general. In other words, if you're a 1/4 moa shooter, and your rifle is a 1/4 moa shooter, there shouldn't be a reason why you can hit a half moa target cold barrel.

Or dead of exhaustion after 20 feet!...but there is a bright side here...just have to roll the tops up a bit more and you you're already contained in a water proof and insulated....coffin!
