Stock length of pull?

[coyotewillie]

How much is stock length of pull going to affect me on a LR rifle? Specifically...I've got a .338 LM RPR and 6.5 CM RPR. I've always wanted to try a Magpul PRS on one of them. But looking at some of my other rifles, they all seem to be "comfortable" at approx 14.5" LOP. I've always felt the PRS stock would increase that too much. But, nothing to do today so I decided to give it a try. Used the Lapua. Shortened up all the way my LOP is 16". I've never minded the OEM stock, but I really like the feel of the PRS. But boy, adding 1.5" LOP is different! Of course on bags, which is how I always shoot, it will work allright to get a hold of. But I'll have to move the scope rings back a couple of notches and maybe slide the scope back in the rings to get a decent scope window just to try it. If it fits me now, and I don't really mind the OEM stock, is it worth it. Sure, all it takes is a little time, move everything, re-sight it in, not really a big deal.

But, what does changing the LOP an 1.5" longer affect shooting? I'm sure it would be a lot more significant on a hunting rifle, but is it going to make much difference on bench/LR type rifle? Will this affect the felt recoil, especially on the .338? I won't have time to try it till next week, figure I'll shoot it like it's set up just see if I can see any problems before I change the scope at all.

You need to determine your actual LOP. If a rifle doesn't fit you, you'll never shoot it well. It instill flaws in your fundamentals that you can not physically correct without a lot of effort. Even then, your mount on the rifle will change every time you get on it. That will affect your shooting period. Too short and you're bunched up on the gun, too long and your reaching to pull the trigger and no longer have optimal contact with it . The stock needs to fit you.

The biggest issue I've seen, with a stock too long, is the inability to get leverage on the bolt and run the bolt. If you have to lift your elbow to run the bolt, your LOP if way to long. Other issues are grip and grip angle that relate the trigger finger placement. Your shooting hand elbow will be moved way forward in the prone position and not provide good skeletal structure to support your shooting position.

at the same token, It never hurts to try. Show us before and after groups and report back with your findings on comfort.

I was able to take off close to an inch if I remember right from the front of the PRS mounting spacer.

Mostly it’s about the consistency of where you cheek goes. Most of use use some type of cheek rest/weld/crane. You (I) would generally want my face to be centered on that CONSISTENTLY before setting eye relief on the scope. So basically it adds to the consistency of how you set up behind the rifle. It’s hard to keep the same head placement behind the scope if you have to move your body around a bunch to find “the sweet spot” and there’s no guarantee that even if you did it was the same spot last time. That’s without the extremes into too short and too long.
