I have cast and shot a bunch of these, and I like the boolit, but settling on an OAL has been a bane.
I use the ammo in revolvers, so crimping over the front edge is how I have been doing it. One conundrum has been how far past the front band to crimp. I've looked in older Lyman manuals and interpolated 44-40 OAL and that would work if it were not for the uneven leading edge of the front band. I have an issue with my sizing die, or my technique, that is sizing my somewhat oversize boolits a bit more on one side, leaving the boolit's band leading edge a little uneven or proud of the boolit ogive on one side.
When seating these boolits, I'd adjust OAL and the odd boolit would crimp and have a small sliver of lead above the crimp. I was a bit annoyed and just started to crimp in the middle of the front driving band. The finished cartridge looks good, shoots good, and I just don't see a downside to crimping my ammunition like this.
A quick investigation online and in my books, did nothing to enlighten me on this practice.
Is crimping in the band an acceptable practice? or not?
