For .223 it had been among my least most loved powders even though as my 3031 supply was all more mature and I have read the new things is shorter. It wasnt unheard of at all for spilled powder thanks to bridging challenges at the case mouth.

For OP’s purpose I'd throw fifty or so charges and weigh each one to find out what sorry of statistical spread I could hope.  Then try out to find a load in which that standard of dispersion can be Risk-free and after that evaluate precision.

that is a compressed billed (just about anything more than 25gr with 3031 inside of a 223 Rem situation might be a compressed cost) and needs to have a slight crimp in website it. I have shot these loads crimped and un-crimped plus the crimped shot much better than the un-crimped for a few explanation.
