There are some rifle bullets I will stand up and the hardware cloth does the trick for the smaller diameter, 32 caliber and smaller. The larger rifle bullets really don't need much help. But handgun slugs get layout and spread in a single layer. As I said I use the same baskets as CW, which make it easy to do the shake in your plastic tub and dump into a basket which is over a cookie sheet and just shake the basket for the excess powder to fall through onto the cookie sheet. Next I just make sure the bullets are not on top of another bullet. Some don't care, just dump them in and shake off the excess powder and bake the pile. Any of it works if you immediately dump your bullets onto a towel for AC, or into water for quenched bullets.
As far as quenching goes so far I am not finding the need for it. The old, 30 to 40 year old COWW I have age harden up to 18. Most of what I'm doing rifle wise, is better no harder than about 12. Handguns at 6 to 7ish under 800, and about 9 to 10 for magnum handguns. Still working out the blend, all of which is on hold till freeze up.
