Thread: Issues Seating Cast Bullets

Need to use a die such as Lymans M die to create a .308 clearance step in the case mouth. I think Lee may do something that will do a similar job.

New brass can be hard to load with the first loading. I run an expander die thru them.

Biggest issue though is probably your seating stem. How well does it fit the tip of the very flat nosed projectile? Not very well I would say.

If you expand your case mouths with something like a M die (I usually go 20 thou deep) you can usually push the projectile in and align it reasonably well before seating. Your seating stems will not align the projectiles say like a spitzer is aligned with a standard seating stem.

Gas checks should be easier to start than straight lead based projectiles.
