Brass was older still- W.R.A. 25-20SS brass. Lost several during this shooting session. One or two drop out each time due to splits,cracks, etc. Small supply of new .25-20SS Jamison brass on its way here. More to follow as I can afford them. (Once, a few years ago I spent $100 on a minty boxful of Rem-UMC .25-20SS cartridges- quite the collectors item. I then proceeded to pull the bullets and turn them into R-2 Lovells.)

I have always had good luck with 50gr. Blitzes. They were my bullet of choice in my last HiWall R-2, and so far they do well for me in this one. I'll agree with you re: old Sisks and W-M's. I too shot away a boat load of them over the years, but it was more of a nostalgic experience than one of precision shooting. The tiny group was fluke-ish, if you recall the rest of that paragraph. I would say the gun is a solid sub-MOA performer, and quite probably will do even better with some higher quality bullets. But for now I'm satisfied.
