I don't believe everything I read. That's why I asked the question here. Your answers are more likely to be based on opinions developed from experience.
Guess I'll give it a try in the .223 and Garand. This is for full length cas checks only (jacketed bullets). I don't have most of the calibers suggested above. I have a bunch of handguns but only a few centerfire rifles that get shot regularly. The Garand loads are loaded on a Rock Chucker but I prefer to load .223 on my 650. I'll see how the logs meter. The Dillon measure is very good with Varget so maybe it will be OK with 3031.
I'll eventually be shooting cast boolits in a .375H&H (as soon as I find a nice stock at a price I like) but 3031 may be too fast even for cast loads in that huge case.
The input is appreciated!
