Another shameless plug for the 625JM here as a better choice for 'major' power factor, if that is your desire. A 230gr FMJ .45 ACP round just has to make 718 fps to exceed 165 pf - that's pretty mild. Nothing loads faster - even in my stumbling mitts - than moonclipped RN .45 ACPs in a 625JM - as if they were magnetically attracted. On the other end of the spectrum - X8 moonclipped .357M's in a 627 - as if they were magnetically repulsed - trying to align the spindly wigglers is fun under 'the clock', too.
Years ago I was plinking away with my 696 and some 240gr LSWC's that barely made 700 fps from some Titegroup in Starline .44 Russian cases (It makes a 'cute' round...). A range friend came out with his 9mm 'race gun' and his latest 127gr +P+ load in an attempt to make major pf. After a couple of jams, he looked at me and said it must be nice to just plink away with 'poof' loads. I let him shoot a few - he commented on it's low recoil, but easy dropping of the steel plates. He was shocked to learn that it made major pf. Sometimes being big, heavy, and slow has it's merits!
Of course, it's overkill if minor pf is all you need.
