After reloading for the 45 Auto for 50+ years, without a checker of any sort, 1st on a RCBS Jr single stage, then since 1987 on a Dillon 550B, no problems to speak of*. Until WB came along, I'd only loaded two bullets in the 45 Auto. A H&G 68 for target work and Speers 4477 HP for SD. They simply worked in all 4 of my 1911s, a Gold Cup, surplus Navy issue Colt, a parts gun I built and a Combat Commander. This entire time I loaded using the same RCBS die set until I got the Dillon. So... in 1987 I began using a Dillon Carbide sizer, but the kept using RCBS seat/crimp die. Frankly, the 45 Auto is so easy to load for, it surprises me when folks have problems. Cases don't grow in length like a rifle cartridge, if anything, they get beat a little shorter, but that's never seemed to become a problem. I've never encountered a split case. When I put my Combat Commander on my "duty gun" list in 1982, the department armorer found an issue I'd been totally unaware of... Something he called "ramping"... Now, all of a sudden my carry gun could feed full wadcutters. I still somewhat haphazardly load my 45 Auto rounds... a 200 grain RFN in front of 4.3 grains of TiteGroup and a Winchester WLP yield ~800 fps for a PF of around 160. This load works a treat in my two Taylor's Tactical 1911s, a Rock Island, and the 4 mentioned above. They've all been "ramped", had the rails polished and run with oil. Most issues with the 1911 platform are with the magazines and operator. You simply cannot "limp wrist" one. While Tripp Research & Wilson Combat mags are probably the best, my CMC Shooting Star mags have served me well.** The worst issue with the 45 Auto is small primer cases.
* Besides... ain't an occasional bump with the palm part of the standard "manual of arms" for the 1911? š
** I don't care who the maker is... when folks walk on 'em... they're pretty much toast! So watch where you put your clodhoppers! Learn how to keep your magazines clean, follower straight and lips bent. I'm still using some military mags issued in the early '70s. With proper maintenance, they can last a lifetime. (Theirs, not yours, metal does fatigue).
