The .357 magnum is new to me. I know that it will shoot .38 spl. too. I've read that there would be a problem firing .357's in the gun after firing the .38 spl. rounds due to the shorter length. My question is, how many rounds of .38 spl. would I have to shoot for there to be a problem? And, shouldn't a normal cleaning remove any fouling or build-up in the end of the cylinders? Any help in understanding this, and proper maintenance information would be appreciated.

What you heard is right, or at least it is with my Ruger GP100.
Tooh it to the range a few weeks ago, fired 50 rounds of .38 special and then switched to .357. I had a tough time getting the .357 rounds into the cylinder all the way due to the ridge that formed in the cylinders. I ran a brush through the cylinders and it helped but when I started cleaning it I could still feel and see a ridge. It came out with a good cleaning, brushing it pretty briskly.
If you're going to fire both rounds, just fire the .357 first, and you shouldn't have a problem.

You should clean your chambers well after practicing with 38Spls. I use a chamber brush which you can get at Midway or Brownells. I've shot 38s in 357 Magnum revolvers for some 40 years without any problems.

just clean it before you change to 357mag.

not a big deal...just keep it clean. I've never had an issue with mine and there have been times when I've shot a couple hundred rounds of .38 before switching to .357.

As long as the revolver is cleaned after each shooting session, it should not be a problem. Heat will be a problem before fouling buildup.

Is there a difference between a bore brush and a chamber brush?

wmhawth

Just the size, the chamber brush being a bit larger. Actually I have used 40 cal bore brushes in the 357 chamber for lack of a chamber brush.

I think the type of bullet will make a difference,a lead bullet will create more buildup quicker than a jacketed bullet
