I have a 26" encore rifle barrel in 500 S&W. I'd like to load up some 700's over rifle powders and treat it like a rifle cartridge rather than a pistol. I can seat the big 700 from the recent group buy so that only the gas check and 1 drive band are in the case. That gives me A LOT of powder space.
I've seen in a few places say, "fill up the available space with a slow powder and you'll be fine", but how much boolit can I put on top and how much space can I use before this rule doesn't apply?
Question is, just how much Reloader 7-4198-H322-3031 can I drop in there and still be safe?
