I'm reloading some 115gn Berry's round nose 9mm in a lee single stage press. I noticed in about seven out of ten of my test loads I can spin the projectile in the case. I can not squeeze the bullet into the case and can't pull it out...it just spins. All I can think of is it may be crimping befits fully seated creating little Groove for it to spin in. Is this somthing anyone here has run across? Is it a dumb idea to just run them? Like I said zero movement in or out no matter how hard i squeeze or pull so it seems to be crimping tight.
