In an apples to apples comparison with heavy bullets a 45super covers any thing the 10mm can manage even from underwood and BB can manage and go heavier too .In an apples-to-apples comparison, full-power .45 is significantly less powerful than full-power 10mm, so I'm not sure what you're getting at.
I've already addressed the point about experimenting with different/lighter ammo a couple of times, so I'll leave that be.
Apples to apples - hum You compare how you want to and so will I . I know 10mm can't deal with 255gr loads and know how it works on hogs thru the front plate 30 years an and 180gr or most 200gr are hp for the 10mm and are ammo or black bear load and you can get 1300fps and 676lb fts
The 185gr 45super those a 185gr bullet at 1300fps too and 694 ftlbs . Yea the 200gr 10mm slighter better but are the chambers in YOU pistol up tho the higher pressure of the hot maybe not so SAAMI rated underwood ammo . Now granted hornady helped developed those loads so the tend to be same in a proper chamber and with enough recoil spring .
The 45super 255gr is a nice factory load and will push threw a lot of tissue if in dangerous game country compared to a 200 and do it with a easy to fire low pressure load even at 45 super spec of only 28,000psi . Recoil not bad from a 22ox 4" pistol .
BUt at this point I don't care what you do . I offered some real advise to check the mags and mag release but that you seemed to blow over that so good luck with what ever you do . Now it you live near asheville nc . I might buy your problems pistol .
