I found a very nice looking reduced load for my 458. It was in the MEC manual that came with our shotshell reloader. It called for 35 grains of 2400 powder, 300 grain HP, and a Winchester 8 1/2-120 primer.

I loaded one with 35 grains of 2400, a 300 grain Barnes-X, and a Winchester LMR primer.

The powder did not fill up the case all the way. It only filled it about half way. After seating the bullet, I could hear the powder inside as I gently shook it.

Is this load safe to shoot, or will it cause detonation (Secondary Explosion?) problems? Is the primer I used alright? I coudl find no 8 1/2-120 at the shop...only LMR, LR, SR. I am a little nervous about shooting this load....
