@ 245winxb ... I guess I can smooth out the fins. I'm using a Lee 4 hole turret press.
@ reloader28......not the oal , using 1.107 to 1.112 oal .
@ Edward 429451....Im using a case gauge and yes the barrel comes a little closer with the plunk test but not completely. The gun is a Ruger Sr9c.
@Chris in va......... I'm using a Lee factory crimp die .
@ All of you ........Do you all think gradually increasing the FCD will do it? I am using the minimum crimp. I thought to much crimp will deformed or cut into the bullet , sacrificing accuracy. The bullets are from "Missouri bullet CO" THEY ARE # 18 HARDNESS. THANKS
