Thread: Issues Seating Cast Bullets

I bough the Lee Universal expanding die.
Turns out if you flare too much the case mouths are very very tight to chamber...

Hardly need any flaring at all, I just set it so the flare was the diameter of the brass diameter after seating and it worked well.
Had a few marks from the seating stem on the projectiles but nothing major, I doubt enough to have an effect on the projectiles external ballistics.

Excellent result.

If you flare to much they also are tight going into the seating die.
I usually crimp as well using Lee's crimp die and this makes nice fitting ammo.

Nope, you flare, seat the bullet then use a crimp die to at least straighten the flare back to level, or, if a crimp is needed, to produce that crimp. You never try and chamber a cartridge with the flare still present. Or yes, you will get chambering issues
