Jacketed bullet velocity

. . . shooting cast bullets in my 92 and they shot fine un-till I leaded the barrel . . .

You would need to clean the lead out before switching to jacketed bullets. Honestly, I don't know how many years its been since I cleaned 45 Colt's barrel. It does need it.

I shoot nothing but cast bullets in my .38/357 R92, .44 mag B92, and .44/40 Chiappa 92. Some are coated; most are conventionally lubricated. I also shoot the same in my handguns. I've never experienced leading.

Perhaps I have had good luck because I shoot relatively mild loads and always clean the barrels after shooting. I also shoot more than ten thousand lead .22s (mostly CCI Blazers) each year and my .22 barrels don't lead up either.

The trick is using a bullet that fits the throat like a glove and an alloy that matches the intended pressure. If you are trying to push a cast bullet a these higher pressures, for starters, it needs a gas check.
