Impressive groups. Looks like you've got the right recipe.👍
My Ruger #1A is particularly fond of 165 Hornady SP's (flat base), seated .03" short of the lands, with 58 gr. of H4350 stuffed into Rem. brass & sparked by Fed. 210 match primers. Velocity from the 22" barrel averages 2838 fps. and (3-shot) groups average about 1" at 100 m. (sometimes a bit more - sometimes a bit less - depending on my 70 yr. old diabetic eyes). I've used this rifle/load combo for years and have killed a few truck loads of white tails and muleys with it.
What man, on his death bed, ever lamented, "God, I wish I had spent more time at the office."
