While looking for very soft-shooting 45 ACP loads, I saw “The Geezer Load” recommended a few times.
“So, here’s the scoop on the Geezer Load. Using mixed cases, with Winchester large pistol primers, and
Berry’ 185gr. HBRN bullet, a charge of 4.3-4.4 grains of Hodgdon’s Clays gives a velocity 758fps. The finished
rounds are loaded to an OAL of 1.250” and are crimped to .468”. The load is as close to 100% reliable
as it can be in my full size 1911 Government model pistols when they are run with 16lb. recoil springs.”
I double-checked a second source for safety. Hodgdon says that a Fed 150 Primer + Winchester brass + 185 GR. HDY JSWC + COL 1.135″ gives:
4.5gr Clays 855fps @ 14,500 CUP
4.9gr Clays 981 @ 17,000 CUP
I did: Mixed “Brass Guys” brass, Winchester WLP, 4.3 grains of Clays (first individually weighed, then #45 on the Redding 3BR), Berry’ 185gr. HBRN, OAL of 1.2650″, to match the OAL of Magtech 230 grain hardball. I used a lighter crimp. I figured that I could always seat deeper or add more crimp later if needed.
Firearm: Les Baer 5″ 1911

LabRadar Series: 92
Velocity: 755 fps avg (777, 713, 742, 776, 755, 739, 691, 797, 762, 733, 808, 773)
Spread: 808 – 691 = 117fps
StdDev:33.9 (12 shots)
Notes: Did cycle the the firearm, although I may try a shorter OAL next time, since with some magazines the feel of letting the slide down could have been smoother. Somewhat dirty — I will consider upping the charge for a better chamber-seal if there is gas blow-back. Power-factor looks about equal to 9mm. The spread is unfortunate. Pretty neat that my average speed was so close to Markwell’s figure.
