If your twist is around 14 then i would suggest working up a load using 40 gr Vmax
But I have a 10 and it loves the 50-53gr Vmax.
I like the 53gr Vmax (hard to find) but shoots flatter and tighter groups for me.
I used to try and Zip them up and load for speed. A few blown off legs and a bobcat that was almost cut in half, made me rethink that.
I slowed them down and got really picky and started to load for the best accuracy i could, using the slowest load i could. I ended up below 3700fps and shooting .3moa groups with a factory stock light weight hunting gun. I get a lot less blowouts, but when i do it's my fault and hit a bone of something, not the bullets fault. Better yet, I only had one runner this last season, and it only went 30yrds in a half circle. (death run)
