Re: Bevel base wadcutter
DLM, that load sounds a little stout to me. It exceeds most of the max recommended loads I found after a quick check of my manuals. I found one loading using a Lyman #35891 BBWC (Linotype) that lists 3.8grs start and 5.3grs max which pushes that bullet at 1013fps., CUP of 16,700 Pretty fast for a target bullet. Your load is right at that one. It lists OAL at 1.317 for that bullet. When at max loading seating depth can have critical effects on pressures so proceed carefully.
It is not uncommon for BBWC bullets to have a crimp groove that when used would give the results you are showing.
Other loads I found for Wad Cutter Bullets are:
150gr. Lyman #385091, Unique, 3.7start, 4.2max, 1.317 OAL
148gr Hornady #10108, Unique, 2.4start, 3.5max, 1.180 OAL
Alliant Powders lists Unigue with 148gr WC with a 3.2gr. max.
That 148 gr. Wad Cutter is normally loaded as a target round at velocities in the +/-700fps. and CUP Pressures around 1000. Why are you loading that normally low speed target bullet so hot?
