Strobes, outside temp was around 90 degrees and humid. I did not do the round robin which i should have, but shot a string of 4 loads ( 12 ) at once before cooling. Barrel was not smoking hot though, it was just the temp that needed to be cooled down. I don't like shooting long strings in hot weather. First group was unofficial due to a clean bore and that clueless flyer on 2nd group, must have hit a mosquito on the way to the target, lol. Kidding aside, the H4350 performed better and more consistent than the H414, Hybrid100V and RL17. It's my first test with H4350. I still have lots more room to increase charge weight, the velocity is almost reaching 2900 fps with just 40.3 grains. But I'll sacrifice speed for accuracy. I have pushed the 130 Berger at 3,075 fps with just 43 grains of RL17 without case or bolt pressure signs while I was searching for H4350 several weeks ago.
