Is this a typo ?
My Lymans 48th says on page 334 OAL for a 38 special 146 gr hp 1.408...all the others are 1.480 or1.470...I'm just wondering...but got some 140 grain hp and noticed the oal difference...

I believe that the 146 grain bullet is the old Speer half jacket bullet which doesn't have a crimp groove. the case is crimped over the front edge of the bullet. with bullets that have a crimp groove the oal length is determined by the crimp groove
