Interesting comparison. Do you see any differences in Joules between the HP68s and the Canada Riotballs? You should definitely try the Grimburg JULv2 vs. Canada Riotballs for Joule output and accuracy, round ball vs. round ball.
Well I kind of did the best I could, if you piece everything together, lol. But, it's kind of not a fair comparison. I can't put a 683 barrel on the vks so there's no way to accurately do it without Canada being at a disadvantage. But I got 52 out of them and 53 out of the V2s the same night.
I hope that makes sense I mean I can definitely shoot all three of them through the vks and see how they do which I have done just not all at one time in the same video. But like I say it's not really fair on the Canada rounds because they're designed to be shot out of a smaller barrel
