.458 bulging Starline

[laowho]

No specific reason other than that I've read that OE likes lighter compression--until Don of course! But I wanna cover as wide a range as possible. Still have another 140 bullets.
For foulin have heard that OE maybe fouls a lil softer and is more amenable to blow tube which I'd like to do if possible. Figure it mite be sumthin of an art? Am equally prepared to wipe of course. Guess just water for that, and if lite enuf no dry wipe behind it?
The bullets are from Chey Cast Bullets, 20:1 @ 11BHN. They look Postell-like?.

oops...530 gr, and they are Postell

I'm an idiot. What I thought were 415 gr RN are actually 512 Gr. Well good for me. Keep hearin that the 45-70 prefers such. They measure .458 on the nose and received them in 3 days.
