hey guys buckman again. i am loading min charge in this load the start load with 60 vmax with varget is 33 gr i started with 32.5 three shts. by the third shot could hardly get bolt open when i did it had blew primer out i dont get it. should i try another powder thinking 4350 or4320? this gun has always shot 60 gr bullets the best

I don't know. That should be a safe load. I think you'd have to look at other factors. Is it a custom or factory barrel? Had the cartridge been in the sun for a period? How long was the round in the chamber before firing?

Check your powder scale.
