Bullet coating?

[laowho]

Thanks Bruce,

I had thought that for the riding noses I'd use 18:1 to help compensate for bumping up so that's what I used, 20:1 for the others. But good for the lube on the nose then, understanding that BP prefers animal and veggie fats. Thx. As for the sizing, well I'd thought the Shilohs are a bit tight (.450-.457), and that as long as I was .001-.002 over groove dia. I'd be ok, so I got the .458 sizing die. And if I hadn't, dunno that they woulda fit the S'line even after annealing. Figured I'm still getting an obturated seal and not bulging the cases as I had in the beginning when I seat. Moreover, as for the seating die, that's absolutely necessary. Otherwise I'm misunderstanding you and should be using a .457 mould, but that just sounds contrary to everything I've read, maybe b/c others aren't giving the obturation effect its full due? And my casting temps are correct acc. to the finish of the bullet, neither frosting nor shining, if that has any effect on the final bullet dia. Cheers, Doug
