I was looking around for some lower recoil ammo options in .45 and found this. After a quick look at DocGKR’s recommended ammo list, it does have a 185gr solid copper HP on there (not sure if the one used by PNW is Barnes, though). But what speed should they be going at? The PNW Arms lists their load as going at 965 FPS. That sound about right, or is that too slow?
I believe Barnes’ non-+P loadings are running around 900-950 FPS. Most of the +P loads it between 1050 and 1100.
Personally, i would stick to higher velocity stuff, but I don’t find the +P loads’ recoil to be objectionable.
