So far I have only used the load that I found that works best in my Sig P 210's and tried it today in my 952-1. My first 40 round group at 88 yards measured a little over 7 inches. It must be about the same as the man who used her last used because they were center hold and about 4 inches to the right, but the sun was far to the left which could account for the windage.

3.4 grains of 700 X
Rim Rock 122 grain TC lead bullets
Over All Length of cartridge, 1.34.

I found that the TC 122 grain lead bullets were much more accurate at long range than the 115 grain lead round nose.

I like to judge accuracy on groups of at least 50 shots, it is easy to shoot a smaller group with 5 or 10 shots but I feel the more you shoot the better your prediction of accuracy.

SR 7625 proved very accurate, but I did not have enough to shoot it a lot, that powder is very scarce here.

After shooting I always run a brush filled with bore butter through the bore.

I find mine an absolute joy to shoot, hope you do also.
