I had Lone Wolf build a carbon fiber stock back in 98. Took the gun from 1 1/2 to 7/16.
With the new 87 Bergers I am putting a lot of them in 1 hole @ 300. Been shooting 1000
with that bullet as well.
Lone wolf has sold, but they are still local up here. http://www.lonewolfriflestocks.com/
I think the buyer is one of the Google investors so it's a well backed company. Proof Research.
