I cast 59 sample bullet from the RCBS Keith mold in a scrap alloy that tests about 10-11 on the LBT hardness tester and does not age harden much more than a point in two weeks. They weigh 269 grains on average.. Kinda heavy for a 250 grn mold. They run 0.429" on one side of the parting line and 0.431 on the other.
Other than powder choice, charge weight, primer choice and maybe degree of crimp, I am not sure what else I can adjust that will produce an accurate load from just another load, by that, meaning the "the also ran's".
I am going with a few load levels of BE and RedDot to start with, Wolf LPP primers and, a light crimp. It will be a few days until I can get past the deep snow that just arrived to know much on the target.
I'm not sure the Chrono numbers mean much so I will leave that at home. The target will say.
