What is so super about the 38 Super?????

I don’t really know, but I’ve gotten so attached to the 38 Super over the years. It’s a somewhat difficult cartridge to hand load. Its supposed to take a .356 bullet; but people have used .355 and .357 bullets in it. The biggest problem with the 38 Super is bullet setback in hand loads. Neck tension has to be tight. The bullet hits the feed ramp with considerable force. The can force the bullet back into the case and create very high pressures and a case head blow out.

My own 38 Super Colt Model 1911 started out as an ugly well worn project gun. With a trashed barrel, poor refinish and buggered trigger, it appeared beyond hope. It’s serial number placed production in 1958. However, the slide and frame and internals were in good shape, well worth the bargain basement price.


A set of Millet sights, Bar-Sto barrel and bushing, new trigger and parkerized finish put this gun right. The interest of the 38 Super is that it started live as the mild mannered 38 Automatic Colt Pistol cartridge in the elderly colt Model 1902 Pistol. Loaded to +P pressures in 1929 and chambered in the reliable and strong Model 1911 the super should have been an instant winner. It was not. The head spacing on the tiny cartridge rim ruined the accuracy potential of the cartridge. Its power was soon eclipsed by the much more powerful 357 Magnum in 1935.
For decades the 38 Super was a minor player; an unpopular second chambering in the popular model 1911.

In the 1980s the 38 Super was rediscovered action shooters, it could be hot loaded with fully supported barrels, to make the “major” power factor. New barrels that head spaced on the case mouth and solved the accuracy problems of earlier barrels. Since then, action pistol has moved on to 40 caliber guns. The 38 Super is now a modestly popular cartridge with a few enthusiasts. Personally, I think it’s great!!

  1. Nice blog and some really cool stuff. I recently started an ammo collection and was wondering if anyone else is into this. I am trying to collect one each of as many calibers and variations as I can. I also collect vintage firearms advertising and cartridge boxes, etc. I also started a blog here. http://ammocollector.blogspot.com/

  2. The .357 magnum is only marginally superior in ballistics to the .38 super auto or super comp. Some revolver loads in the old Speer manual suggest velocities of only 1075 fps from a 4" barreled .357 158 gr. so flash gaps play a big role in velocity. You can get a 140-147 grain bullet rolling at over 1200 fps from a .38 super auto and having quickly reloading clips makes it superior to the .357 magnum with only 5, or 6, or 7 rounds in new Ruger revolver.
