I'm using Unique powder and a batch of 220 grain flat point Berry's bullets. The Berry's website says to use the powder manufacturer's data, but Alliant has no data for the 220 grain.
They have data for 225 grain: 11 grains Unique.
I want light charges because the revolvers are 29-2 Smith and Wesson revolvers.
My favorite bullet for these guns is the 240 grain SWC plated with 7 grains Unique. That gives an indication of what kind of rounds/recoil I like in these guns.
I'm thinking 7.5 grains/8 grains Unique for the 220 plated. The closest bullet in the Alliant data is a 225 grain cast with 11 grains Unique. That's stronger than I want for these guns.
Thoughts?
