Shot the replacements in a two gun at Holton last weekend. Had around 12 rnds of load development prior to match. First two groups were a .184 and .130 From there on, I had a hard time keeping my head from sliding up my a**....you get the point. Like a friend once told me "I managed to snatch defeat from the jaws of victory".
At no time during the two days, did I go to the line, or see on the target, the inability that I couldn't win the match. I am going to do some more testing under a little better conditions but as of right now, I believe they are a competitive bullet.
As far as staying in tune....same as very good other bullets I have.
Wind drift....normal.
I could say a lot more about them but want to double check my opinion before I post it (like anyone would be interested anyway). Like the window of seating depth. I do know that one time (due to a distraction) I went to the line with two different loads mixed together and shot a .3XX at 200 yds with a whole click difference in the loads. I didn't realize it until I went to reload and seen the different setting on my measurer. Maybe I just got lucky...maybe not but these are a couple of things I want to test.
