Without it start at beginning loads and be careful. Just make sure your rifle has the considerable freebore that was done on the Schultz and Larsen rifles, the first commercial rifles after Norma released the specs and ammo. (I have a 22-250 that is a 98 action and it has a bunch of pitting just below the wood "near" the ring, not an issue as far as I can see) ( Upon obtaining this rifle it had the worst fouled barrel I have ever encountered.3 weeks of daily cleaning till it finally ran out of green) I am not a metallurgist, A concerned owner YES. Crest had been ground off but not completely, since these receivers were "surface" hardened it was mentioned that this is not a good thing due to grinding thru the case hardening. Other cautions were about the feasibility of reheat treating a "pitted" receiver and suggested it not be done.as cost wise not a good choice due to the pitting.which are NOT present on this action. It was suggested this Model was Manufactured between 19 and some question as to metallurgy and resulting possible set back of the locking lug area. Gunclbprez I got a "suggestion" from another forum whom I contacted first before this one. Stupid is as stupid does.I ain't stupid! When I fire the first shot from this gun.it will be with the heaviest load using the heaviest bullet.rifle stuck in a rubber tire and using a LONG string! Thanks for your reply s, Yeah I know, don't EVER trust others reloads. Brass.you name it, he had it! More than 50% loaded ammo. But when I go back to his house (after a reasonable time after his passing) I will look to see if he managed to make casings. I did not see any 7&61 brass in the previous owners stock.and believe me he had a bunch of different brass. So to answer your question, yes I am going to use 7mm Mag brass. I just happen to have the dies and casing to do just that. which can be made from the 7MM Mag brass. I know that the 7mm Mag spelled doom for the 7&61 S&H. I have more photos and can take others if needed. I need more information and the experience of others with more knowledge on this subject.
I had queried on another forum but did not get the answers I was hoping for. Not sure when this action was manufactured, but have seen instances of 95, 96's action destructed tested which took way more than the 50,000+ psi of say a 257 Roberts +P loading. I have some pictures to show and will try to attach if allowable. I did not see any tooling at his place that suggested he put this action together himself, he did have a lathe however, I did not see a vice strong enough to use for barrel work. Even if he was still with us he didn't have complete control of his memory. The rifle appears not to have been fired and I cannot ask the previous owner as he just passed this week.
I am not able to tell what size the shank is. The action is large ring, 7 7/8 attachment bolt spacing. My question is is this action of sufficient strength to use this chambering. I acquired a 1910 Chilean Mauser chambered in 7X61 S&H in the white with a Belgium bolt fitted (or so I am told).
