Finally have the time to start casting. Started with the Lyman 429421. One side was .427 the other .428. Good thing I only cast 600 before miking them. I was getting 247 grn though. Sent that one back and replaced with RCBS 44-250-K. Diameter is good but am getting 262 grn. Thats ok with me the more the merrier. Where should I start with 2400 and where should I stop? Need to get a chrono after I explain the cost of casting equip to the wife. Also casting for my 460 Guns and Ammo 535 grn Rcbs mould. Thanks Don
