Tons of folks, me included, ditched some rather valuable small Scope Ring 7.62 Nato milsurps like the much more rare FR-7 companion to the Spanish FR-8 I have over all the bad advice on this. That’s not to say an improperly done conversion, or a receiver with bad metallurgy/heat treat/whatever… couldn’t fail. But the same is true for a large-ring Mauser action in 7.62 Nato/.308 too. Any links to the tests? I have a rifle, that has the Kimber name on it , that is a conversion of an M96 swede to .308 with a heavy barrel. Shot it for years without a problem. BTW… it’s H.P. White Labs… “Price Waterhouse”… WTF was I smoking for breakfast this morning. Samco had a big thing up on their site about it a few years back. Now it’s mostly message board archive references to it like this: http://www.thehighroad.org/archive/index.php/t-40448.html http://forums.gunboards.com/showthread.php?151928-The-dead-Horse-and-the-93-95-Mauser-converisons This of course isn’t to say someone couldn’t fark up a .308 conversion of a small Scope Ring Mauser into something unsafe, just that there’s been a lot of folks who like to act knowledgeable and say ANY small Scope Ring Mauser rebarreled in .308 is inherently unsafe are full of it.How big is the 10 Scope Ring on a target for CMP type shooting (20/10 prone, 10 sitting, 10 offhand) on a reduced course of fire conducted at 200 yards? How about the X ring? I would like to make some steel gongs of the same size. Thanks 30calshooter
