Went out yesterday to shoot the Cutting Edge .375, 350grain at 3050 fps with the GS Customs 414 at 3130 fps. The Cutting Edge were shot out of a 375 Terminator, this barrel has always been problematic, always badly fouled after 25-30 rounds. I have tried everything I can think of but it still does it With two bullets remaining from yesterdays shoot, I went the range to check it's zero this afternoon. It was as it should be & put the two in the same hole less than 1/8 moa group, with plenty of copper clearly visible in the muzzle...... The end result was .25 moa difference in elevation, 4.5 moa in windage, some small sub moa groups & a broken rock I'm not entirely sure why there was such a big difference in windage ? The elevation difference was about what I expected, in my rifles at that distance the 350 does appear to have a higher BC than the 414, especially when you take into account the speed difference. Here is the video at 2050 yards the rock is a different one to last time & slightly bigger, under 1/4 moa, 3-4".
