I just had a NEI mold rebored for a SSK 330gr.GC .429 bullet for my 44mag Contender. Now that I have the mold and have cast some with it the bullet with the lube and GC is close to weighing 349GRS with WW and alittle lino to sweeten the pot. Now do I use data for a 330gr. bullet or a 350gr. bullet??? Some would say this is to heavy for a 44mag and better for a 444,ect. Any help, opinions ,or insights on this would be greatly appreciated. I know I'm probably up against the wall with this weight bullet but would like to hear of anyones thoughts on this. Thanks!
