9mm bullets going sideways through the target!

i do not trust a Lee sizer to be where I paid for it to be. Although usually good

Trust, but verify. As they say…

I resize with a Lee punch to .357 after powder coating.

My melt is SN 1% SB 2.57% PB 96.4% @ 11.3 BHN. I use SOWW + Hardball.

I reload with RCBS carbide dies and use a very slight bell; just enough where the base will sit in the brass. I apply a slight crimp whereby the loaded cartridge, when bullet end is pressed hard against the bench, will not set back into the case. COAL 1.080.

Powder coated boolits yield 124.6gr - 125.2gr. and .3575 - .358.

I shoot WSF powder on the upper side yielding 1055fps - 1095fps in different barrel lengths. All Glock pistols.

No leading or tumbling with acceptable accuracy to 15 yards. Shots are off-hand on clay targets.

I would slug the barrel and check sizing.
