Hi guys,
yesterday I went shooting my 300 PRC B14 HMR Bergara for final tweaks of the load with tuner brake....it was the very same indoor range as always, same distance, same temp., logically no wind, same shooting position, scope, optics...I'm quite confident that like nothing regarding rifle and environment has changed. I was shooting batch of handloads with exactly the same specs as the load before. I compared those two batches and everything seems to be the same (CBTO/COAL, primer depth, whole procedure totally similar, same powder and batch of bullets, primers), but didn't have the time to try previous load again. To my surprise, some fine tuning with EC tuner brake (which previously gave me good results) wasn't at the table as the groups totally scattered from I'd say decent ones to this failure. I put pics of the previous (working) load target and this failure. Any ideas what could have cause this? I'm even more nervous about it as I have some local comp. next week
Thanks a lot in advace and have a nice day.
Best,
T.
