Why does magnum movement matter for rifle accuracy?

[Funzy0798]

I've been thinking about this some recently in regards to barrel whip and recoil as a function of accuracy before the bullet leaves the barrel. Also the fact that a muzzle brake doesn't actually do anything for the primary recoil until the bullet exits and gasses can interact with the brake. Makes me lean away from the whole ultralight rifle trend

But if all things are consistent, accuracy is a product of all those things.

If the rifle does all those things reliably consistent n you dope the rifle, all things being repeatsble, it doesn’t effect accuracy

Reality check time: In terms of how any of this affects the mechanical accuracy of a gun, virtually nothing at this level is going to be of consequence to a hunter. F-class shooter? Maybe. Developing a flinch from heavier recoil? Certainly. But in terms of what's actually happening mechanically, unless someone's hunting squirrels past 500yds, it's just bench-racing ad infinitum. It doesn't matter.

Regardless of anyone’s claim in either direction, if you can show your work it cuts thru all arguments and theory. Rather than talk about it and make claims, I think everyone here should actually try it and show results. Timed circle drill at 100 yards done twice with similar-weight and configuration hunting rifles, one with sub-10ft/lb recoil, and one with more than 20ft/lb recoil. Shoot the drill a couple times so the excercise itself isnt “cold” , repeat, then compare scores. I challenge anyone here to show they can consistently equal their little gun scores with a heavier recoiling gun. Remember, time counts. THIS^^ is the claim when people say its harder to shoot a bigger recoiling gun. It includes follow up shots and it assumes a time-limit and it assumes getting into multiple positions on the clock so any errors in form are most-likely.

The drill: target has 4 separate circles on it, 7moa, 5moa, 3moa and 2moa. Each circle is shot twice for string of fire 1 and 2, and once for #3. Each “drill” is shot on the same target sheet in 3 strings of fire. Every target circle starts standing with all of your gear carried/stowed exactly as you walk around while hunting—ie pack on, empty chamber, etc if thats how you hunt. String 1 has no time limit. String 2 is the same, but each pair of shots has a 20-second time limit. String 3 is one timed medley of 1 shot at each position/target in 60 seconds. I do the drill in this order:
7MOA circle = 2 shots offhand
5MOA circle = 2 shots sitting unsupported
3MOA = 2 shots sitting or keeling with sticks or backpack
2MOA = 2 shots prone
(All 1 shot in the third string)

A hit in the correct circle is 1 point. Outside the circle its 0. The score for a drill is your number of hits, with a max of 20 points. In this case score is 15/20, and I clearly need to work on my offhand.

You mean there's other ways to shoot for practice besides benchrest?

But I'm 1/2 moa all day with my lead sled........
