Aftermarket stock

[aam]

G’day fellas,
I’ve got a Remington 700 long action that is chambered in 375 H&H.
Being now in my 60’s I find the recoil more to my disliking.

So now I’m looking at an aftermarket stock which I can use for hunting and target shooting.
This rifle will be a switch barrel job, 375 H7H and 300 Win mag. The barrels will have Muzzle breaks.

The stock I’m looking at is from GCPD Arms, https://www.gcpdarms.com/msp-m700-la-tac-1-ub-remington

Now the mag well in this stock takes Accurate Mags in CIP length which will be great for the 300 WM.

But now I’ve got this crazy thing going in my head, will a 6.5 PRC, load and feed in an Accurate Mag made for 300 WM/375 H&H in CIP length?

Appreciate your thoughts.

aam
