I had 25 cases left and did 5 rounds each every .2 grains. For whatever reason I also had it in my mind that I was pushing the upper end of published #'s there, but see now that I had some more room to play with. If I had to guess, there's another node somewhere in the mid-upper 75gr range. I'll probably explore that in the future, also. Still just kinda playing around and letting the barrel settle in and getting a feel for things. Now that my cases are all fire formed I'm going to do just a little more testing to verify, then take it live at longer range.
Even at 2915fps Avg, though, if it continues to group and ES/SD stays in that ballpark, I will probably run it. Solidly supersonic to almost 2000yd with 225's, would be over 2000yd with the 230 A-tip. I can leave well enough alone. Another 85fps at the muzzle doesn't add up to much way out there. That being said, I think the barrel will speed up a little over the next 100 rounds, too.
The first 5 rounds nearly copper plated the bore. After cleaning, the next 5 also heavily coppered, though not as bad. The following 15 were better, and these last 25 barely left anything. So things are starting to smooth out a little. I'll see if I can borrow a bore-scope next week and check the throat out.
