Not a heavy bullet, but it is 45 AR...
Sierra manual shows an Auto Rim load for 185gr Winchester JHP (I hope this crosses over to the XTP) over Unique at 1050-1100fps. Doesn't show pressures, and there is no warning/suggestion/admonition to not use the load in an M1917 New Service revolver.
It is not my intention to use this load for punching paper, just the occasional critter.
Thoughts? Hints? Suggestions?
