I shoot my cast lead bullets first followed by my jacketed bullets at all my handgun range sessions. Done this for about 35 years with no problems and have little to no lead to clean out of the chambers or barrels.

Many disagree with doing this since they believe pressures will build abnormally high if you shoot jacketed bullets into a bore fouled with leading.

My opinion is, and it is only an opinion, that this is a carryover from shooting high powered rifle calibers; shooting jacketed bullets in a lead fouled rifle barrel may boost pressures; but not in handgun calibers like .38 through .45.

I know of no official tests that were done to prove or disprove the thoughts or theorys about all this.

If anyone knows of tests, please, I'd sure like to hear about them.
