I have the stock bedded (the stock dug out and completely rebedded) every time the barrel is changed. He bedded the McMillan with Bisonite and Marinetex (bed with one, skim with another). I'm not sure what you're talking about by 'old style national match bedding', but the guy that built my M25 (and others) is also the guy that is in one of those vans you're referring to - he's the Navy's NM armorer. That's unmodified in an old USGI synthetic stock.ġ18SB, just a few comments on your post. It doesn't shoot little ragged holes but it never really gets beyond a couple MOA which was good enough for me. I've got a Smith Enterprises forgery M14 style shooter. Tank's Rifle Shop (down the road from me) does a neat steel liner and modifies the receiver legs. There are a couple of methods like you're saying to ensure the barrel stays solid and most involve bedding the action at a slight angle so the handguard ferrule on the gas system pulls it all down together tightly. The old team armorer vans that went to all the big matches even had the tools to do it on-site! The lugged receivers were an attempt to make it sturdier at the cost of weight and bulk. The service armorers used to skim bed every several hundred rounds and totally mill out and re-bed the entire rifle after about a thousand rounds. The old style 'national match' bedding shoots loose too easy to be of any practical use outside of the range.
