lead bullets getting shaved while seating

[russt]

ive been reloading for my 30-30 for years with gas checked lead bullets, i recently bought a 1000 lead bullets that werent gas checked and i keep shaving them as i seat them. they are sized at .309 which is the same as my previous gas checked bullets, i cant find any adjustment on my seating die
(RCBS)to expand case mouth a little more to stop this. i reload 357 and 44 mag with lead as well but never had an issue since i bell case mouths. is there a way to bell or expand the mouth more on bottleneck cases? please help!

Lee makes a universal expander die that might help. It's just a inverted cone, so you'd need to have your brass all trimmed to the same length or some might bell more than others.

Thr RCBS Cowboy 30-30 die set is designed specifically for loading lead bullets. The second die is an expander die designed to bell the mouth of the case to prevent shaving lead. I believe that it is available separately.

Just run your chamfer tool on the inside of the brass a little more. This should solve the problem.

Could it be the seater plug is screwed in too deep and crimping to early?

Cast bullets for 30-30 WCF are normally .309 to .311. The re-sizing die's expander plug only expands the neck of the cartridge .307, I believe. Shaving lead with standard dies is inevitable. The neck needs to be flared. The previously mentioned RCBS Cowboy expander die or the Lyman M-die are designed specifically for use with cast bullets.

thanks for the advice i will look into getting an expander die. and i know its not crimping too early as i had seater die about 1 turn out from even touching top of case.
