I've been shooting the same 5.5grn of Unique/200grn LSWC load for over 20years now. It should be a shade over 800fps even out of my short barreled Para P12. When I used to have a match type Gov't Model it would make 1 ragged hole outta 7 rounds at 25 yards off of sandbags.
230gr Powerbond plated, 4.5gr of Titegroup... will get you right at power factor for major. If it's warm out.Mixed case, CCI LG Primer.I actually prefer Universal for the 45, very soft shooting powder at major power factor, but since I load 9mm, Titegroup proved to be a one stop powder for both. One 8lb jug will last you for around 12,000 rounds.Not bad
What kind of accuracy are you getting with the Powerbond bullets? I use WST and switched from the Powerbonds to Missouri Bullets 230gr "softballs" and have achieved the accuracy I was after. I could not get the Powerbonds to do better that 4" rested off a sandbag. Thanks.
