Now take it out to 50m. Good shooting. I'm not familier with 4451 as a powder?
A double, I assume?

Got to be a shoulder full. I tested a 20 round batch of 500 plus grain cast in my .458 Win Mag. Normally, I'd get some takers on trying it. Had to finish the whole box myself./beagle

I usually test fire my heavies at 40 yds. This past Sunday I went through 60 .458's with the 462550 ahead of 68 grs. 3031. I can feel your pain...

IMR Enduron 4451, meant to be equivalent to H4350.

Rifle weighs 12 pounds. That helps a lot.
