I have the same problem on 2 different rifles bought in 1995. Both were sub moa rifles after working up reloads. Both have light weight plastic stocks. Both started spreading the groups out to 2". Both Leupold Scopes & mounts passed the physical & rectangle sight in test. Both stocks have warped enough that they are touching the barrel on one side. Both were completely cleaned & copper removed till the patches were clean.

The rifles are:

Winchester 70 Classic Stainless 7remmag

Browning A Bolt Stalker 243

I had the Winchester stock reamed by a gunsmith and it went back to one hole groups.

I have not done the Browning yet as both stocks have aged enough that they need to be replaced.

Any clue where I could find a hunting size stock to fit these rifles? I would prefer a laminated stock, but most of those are benchrest size.
Both these guns are keepers, so I don't mind spending the one on a quality polymer stock with aluminum bedding.
I have also thought about finding a wooden stock and having them glass bedded if I can't find the above. If the wood is properly sealed I think they will out live me.

Both rifles are hunting machines, so light weight & soundness of the stock are a must.

Looking forward to hear your ideas

Thanks! I just found out Boyds can make a laminated stock for both rifles too. I have one on a 204 Model 70 & love it. Not but $89. Sounds like I might have choices now

Just a bit of caution here..I've had laminates warp on me too.....

McMillan is worth the money IMO

I wouldn't buy anything from Bell & Carlson. It seems that many custom gun makers use McMillan.

HS Precision makes a nice replacement stock. The barrel is completely free floating and it has a full aluminum bedding block.
