38 super, accuracy is anything but super.

    I have a '50s Colt 38 Super. I've shot a variety of handloads through it, but everthing goes 3-4" low with about a 6-7" spread. The only thing I can possibly accout for the lack of accuary is all the bullets I've used are 9mm. I can't imagine .001 will make that much difference.

    A thousandth can make a huge difference. It's worth a try...

    Most of the older .38 Supers were not that accurate at all. It was only into the 80's-90's that Colt and other makers started making a true .38 Super barrel and throating it correctly. I would be looking into getting a newer barrel for it, myself.

    The older 38 Super barrels headspaced on the rim, as opposed to the neck of the case as in newer barrels, poor accuracy was pretty common in the old barrels.

    If you can find a more accurate .38 Super than this one, you can have it. :cool:

    I don't suppose 1911 barrels swap as easily as GLocks. Where's a good place to go looking?

    Service cartridges headspace off the extractor all the time, even though they're meant to headspace off the case mouth. Shouldn't make that big of a difference.

    Lot cheaper to try a .356 bullet first.

    This .38 Super is a as accurate as any Baer, Brown, Wesson or Wilson I own.

    You might be surprised. My SV Race gun has 50K+ .356 rounds through it. I tried running .355 and the group was pretty wide. However, with .356 it is insanely accurate. :dunno:

    It can make a pretty big difference, old 38 Supers are notorious for inaccuracy, the fact that Colt changed the design of their Super barrels in the 80s says quite a bit. That said, I agree, a change of bullets is definately worth a try.

    I don't know about old Colt .38 Super (love to get one of those), but the new Colt .38 Supers are plenty accurate.

    Keep in mind that the winners of Bianchi cup typically shoot .38 super. Bianchi cup is one of the most (likely the most) accuracy intensive of the handgun sports. Winners shoot nothing below the 10 ring, and the winner is determined by the number of X hits. Those guns need to (and do) shoot 1" or less at 25 yards.

    I can't remember which of the early great 1911 gunsmiths started making barrels with the headspace off the case mouth, but a solution is a barrel away, with some fitting. My low end Rock Island is awesome.

    I ordered a box of .356s from Grafs, should know in about a week if that fixes things.

    As others have mentioned, some older 38 Super barrels were not so good.

    As BAC, 38 Super Fan and others have mentioned - older .38 Supers headspaced on the semi-rim - a poor design. Modern pistols using the .38 Super cartridge headspace by allowing the case mouth to [FONT=Verdana, Arial]headspace against a shoulder in the chamber. A new barrel will fix your accuracy problem.

    Can I buy a simple drop in barrel, like I did for my GLock? Where is a good place to shop for barrels?

    There's no such thing as a "drop in" barrel for a 1911.
