45 cal Ruger pistols and accuracy with Monometal bullets.
Looking for advice here. I've got a Ruger RH in 45 colt/45 ACP (with moon clips) and a SRH in 454. I load for both and using the XTP bullets (240 and 250gn versions) , I find them acceptably accurate at ~ 50 yards with either red-dots or scopes (minute of deer or better) . For personal/family reasons I'm using mono-metal bullets for hunting with a lot of (basically all) my experience with Barnes (mostly hand loads with a few factory loads thrown in). While the terminal effects are awesome in either platform, the accuracy I am able to achieve in either platform with the Barnes bullets leaves me wanting more. I wouldn't consider them minute of deer at 50 yards with either hand loads or factory loads. (Barnes, or Buffalo Bore). I check the cylinder diameters by dropping a Barnes bullet through them and they all fell through easily, nearly with out slowing down. The XTP bullets seemed to be ever so slightly tighter but they still fell cleanly through the cylinder. Can folks offer some opinion and insight on steps I can take to try to get mono-metal loads that will group at longer distances in these guns? In general, I'm using H110 for 45+p and a lighter 454 load. Thanks in advance.
From an accuracy standpoint you might be better off with a slightly faster powder like 2400, No9, or VV-N110 with those less than full power loads.
I have personally felt that my accuracy with swifts and Barnes in the 454 got better as I went up the ladder into the 40-45k psi range. Single digit ES and 0.5” groups at 50 yards are where I landed with the FA454. The BFR was closer to 1”
