Looks like we're allmissing something here. If this is a 1950 Target or 50 Military in 45 Colt, then that is one scarce and expensive gun. Not sure that I would be using loads in the upper end with Unique. One of the aggravating things about Unique is the consistency of the chrges thrown by a powder measure Although I keep my powder measures very cleann and static free, the Unique can vary by .5 grains and when you are up at the upper end, then the margin fro error decreases. I would be very judicious in the use of upper end loads in a gun that scarce. If I haver misunderstood your post about the gun, let us know and we may find that as interesting as the original question. Take care.

P.S. I have a 50 Target in 45 Colt and I hand weigh each charge when I load for that one. No hurry, I want it right and keep it to factory levels.
