I decided to get out rifles I have not shot in awhile, make sure they are sighted in (the current social malaise is getting to me, I suppose). This is one of them - haven’t shot it since 2013. It has a weaver K10 on it. Lyman 224646 55 gr GC with 10 gr Blue Dot hit point of aim at 100 yd. I didn’t shoot a group with that, wanted to see the sight correction needed to hit with jacketed bullets. The 60 gr JSPs and HPs were 6” high, requiring adjustment of down 16 clicks.
A Hornady 60 gr HP with 42.5 gr 4350 put 5 into 1.5” , and a (bulk buy) 60 gr PSP with 38.8 gr AA2700 put 5 into 1.9”,100 yd wrist rest. The Hornadys were loaded in 1993, the PSPs in 2013.
A friend had one of these, and reported many groups less than an inch, but I never could - maybe he had a solid rest. He has since passed to his reward, and his collection dispersed.
In any event, I could never get this rifle to feed more than three rounds from the magazine. The taper of the cartridge is more than the taper of the magazine box, so if I put in 4 or 5 rounds they seem to cross at the shoulder and jam.
