I am finalizing my build with GAP for a 300 WM.

This rifle would be used for long range large game hunting as well as well as general target shooting.

Here are the spec so far. I would appreciate some pro/cons to the build and any modifications that would be suggested.

REM 700 LA MAG action with Fluted Bartlein 24'' PSS/Varmit countor 11.25 twist. Stock is Manners MCS TA - 90% carbon fiber with spacer system. Badger thruster muzzle break an 20 MOA rail.

The main question I have with the carbon fiber stock. Will recoil be unbearable?

Thanks





Thanks
 
Re: GAP 300 WM build.

The recoil should be fine with the brake.

What trigger guard / Bottom Metal are you going with?
 
Re: GAP 300 WM build.

If you're getting all that adjustable junk in the back then you're wasting your money on carbon fiber IMO. Take a look at the weight difference between the adjustable and non-adjustable stock, that is where weight savings are. If you get yourself a non adjustable stock, then opt for a carbon fiber to save on weight, as it will have a meaningful difference.

You can always raise your comb height with a Triad Tactical or Eagle stock pad, which have adjustable shims and provide a professional looking means to give you a natural sight picture with your scope. Also, the stock pack will cost you quite a bit less than getting all of that adjustable hardware put in the back, which I believe is only useful if the same rifle is going to be shared between multiple people.

A 1/10 twist barrel will give you better performance with heavy bullets, such as Hornady's 225 BTHP or SMKs 230gr MK.

I would go with the Badger FTE brake as well. I've used one with a 300 WM and a 300 WSM. Very effective, feels like a 243 win and you can see downrange impact with no problem.
 
Re: GAP 300 WM build.


Forget the 1-11 twist barrel , thats for 308 weight bullets , ie 175gr etc .

Go for a 1-10 so you can use the 208 , 210 , 220 & 225gr bullets
 
Re: GAP 300 WM build.

Some really great input. I will change a lot of the specs. Your input has been much appreciated.
 
Re: GAP 300 WM build.

Could also consider going with a 7 Rem Mag. That will cut down the recoil!

Re: GAP 300 WM build.

Any opinions on the Kampfeld Custom muzzle break versus the Badger? I was told to go w/ Kampfeld on a build I am having done presently. Any thoughts??? That would be my only seggestion and only based upon my builders suggestion.
 
Re: GAP 300 WM build.

I would lean towards a 1-10" twist instead of the 11.25, so you can shoot the heavies if you ever would want.

If I was lucky enough to have Karl doing a build for me, I would definitely have him install one of his brakes because he does such an incredible job. Since I already own a Badger FTE, it's easier for me to swap it between rifles. It's extremely effective and muscular looking, but some prefer a brake that looks more elegant. If you are having a hunting rifle built, I would go for a more traditional omnidirectional brake; if tactical, hard to beat the FTE.
 
Re: GAP 300 WM build.

I have a 1-8" twist Rock in my 300. I love it, I can run everything from 180, up to 240.
With that said, I would go with a 1-10" for sure.

Also, I run a McRees 3 port muzzle brake. I can shoot all day long, recoil is nothing.
 
Re: GAP 300 WM build.

put a brake on it. agree go with 1 in 10" twist to stabilize a the heavier bullets.
 
Re: GAP 300 WM build.

Not sure if it matters on a 300 WM as much as say a 308 but i don't generally care for brakes on hunting rifles if that is your intended use. I'd also go 1/10 twist for heavier (190-220 grain)bullets which is where the 300 WM really shines.
