Today, I put the BR-Ai to a real test at our monthly 600 yard match. I can't say that it let me down, but I may have let it down. The morning started with fog and ended with heavy mirage. I did manage a second place finish with a 183/2x score. I should have scored higher under today's conditions....especially matches one and two. My load was 31.0 gr of H4895/ Fed. 205 primer/ and seated .020 off jam. The Ezell tuner was set at zero for the first 2 matches (I shot 45/50 in both). For the third match, I moved the tuner in 1 mark (.001) and shot a nice tight group that scored 49/2X. The final match brought a lot of challenges to all competitors. The temperature reached 90 degrees and the wind got to be real switchy. I tried to go into a survival mode, but I lost a couple of shots and finished with a 44. I will be better prepared for the October match....I think??? Good shooting....James
