Here's another question brought up by my quest to load L-FP 122 for 9mm Luger.
The Lyman load for L-FP 121 iis 3.7-4.4 gr of Unique, OAL 1.110". But with my bullets, that OAL causes the lube groove to be partially exposed, with the case mouth sitting on wax instead of lead.
I will need to seat about 0.075" deeper, for an OAL of 1.035", to reliably get the lube groove entirely within the case.
It it alright to expose the lube groove? My gut says no, because the lube can get knocked off in handling, loading, or chambering the round, and because I don't know what hot gasses in the chamber will do to the lube before the round is thrust into the barrel, and because I will wonder if the case can hold the bullet securely with the case mouth on wax. I think I should seat it enough to cover the lube groove, but be very cautious of the increased pressure I'll cause. Is that the correct approach here?
