Can I shoot two boxes of Winchester RA45TP 230 through my 1911? According to Winchester, this round is 990 fps and 501 ft lbs at the muzzle.
Pistol is a Springfield Armory Garrison, 5", .45 ACP. It is a range gun. It currently has a 19# Hammer spring and Wilson flat-wire 17# recoil spring. I replaced the SA FPS with a slightly-radiused Wilson square bottom Firing Pin Stop. It runs both Federal American Eagle 230 FMJ normal pressure 230 HST fine. Magazines are Wilson ETM HD/+p, sku #500C-HD, 8 rounds.
Gun is at 1,699 rounds, including a small jewel box of 20 rounds of Hornady XTP+p (950 fps). My recollection of the Hornady was that while it was a bit spicy, nothing out of the ordinary happened when I shot it. Popped my hand a bit more, perhaps.
The reason for the question is I bought 100 rounds of this Winchester to use at next year's Pin Shoot at Central Lake Michigan, and would like to run it at that match. I want to shoot a couple mags before hand, to confirm it cycles, and maybe the plate rack at the practice area when I get there, but I'm not going to shoot a steady diet of this stuff. Once I get done with the match, I'll go back to regular loads.
My option, if this plan it not advisable, is to put a 23 lb hammer spring in, and install a Wilson 18.5 recoil spring. But I'd rather not take the gun apart, just to shoot this small number of rounds, if I don't really need to.
Ammo for reference.
