Tin Star powder 1st reload .30-40 results not bad

[Baltimoreed]

I experimented with 3 different 170 gr bullets the other day out of my PC rifle. I had been using my NRA but I did the repair on the PC stock. Same 10.0 gr Tin Star, 40 yd off a bag. Two were .308 (lead and jacketed) and one was .310 ( lead gc). I got a 1 inch, one hole group with the .310 and a 2 in+ with the.308. Guess I know what the PCs bbl likes. This week I'll shot the PC against the NRA? Carbine and see what I get.
