What factory loads are you guys having the best luck with in terms of reliability? By this I meen what ammo cycles best without sticking issues. I am asking this question for a friend that had to have one because he wanted to get into long range shooting. He bought three boxes of PPU 250 gr and three boxes of HSM 300 gr. He told me he has put six rounds through the rifle just to shoot it using the ppu and had one round fail to fire. He said it looked like the firing pin struck the primer light. Do the PPU rounds have hard primers or is this most likely a problem with the rifle.
