For many years, I water dropped every thing. A couple of years ago, I started air
cooling hand gun bullets, and at around 12-14BH or less, have found that to be
more than adequate. For little rifle bullets 22-24's, I want hard, and always water
drop, for BH not less than 22, and higher is better. For big 45-70 Bullets, I want
them fairly soft, and normally air cool. For those inbetween, I am comfortable
water dropping and at some place between 16-18 BH. That works for me, but
may not be the best for other folks.
