OK - First and formost. Semi - good news - the bullets you sent me shot terribly. 3" group at 25 yds was the best I could do using 30, 40 and 50 gr of FFFg.
However, the 47 gr RB with a .005" patch and 30 gr of FFFg produced the groups below. The first 3 shots were the ones about 3" low. The next hole at 5:00 in the bull was the next 3 after a sight adjustment. Now this is a new barrel and the range is only 25 yds. But this is a plinker/small game rifle. And it does show a lot of potential.
