I had a buddy back in the early 80's with an old Colt 1911 match pistol. He didn't "know" he should be buying 230 grain LRN or FMJ bullets when he started reloading and bought a box of the big/heavy Keith style .45 Colt semi wadcutters and loaded some up with Unique.
His 1911 ate them like candy and shot nice groups with them. That was the bullet he stuck with over the next few years of shooting.
If your pistol "likes" that load, no reason not to feed it what works. Works=reliable and accurate.
