When I get lined out on the boolit alloy for the 270 I want to try some loads over 2500f/s
Ill powder coat the boolits and work up from about 2000f/s. Lyman 3rd edition list 2 powders Imr 3031,WW748. for the boolits, I cast 280412 and 280473 136grGC and 126grGC
Has anyone tried to push the rifle cast boolits that fast?
What hardness would you recommend for the rifle boolits?
