A small drop of hydrochloric acid will fizzel on ingots containing zinc. Nasty stuff, use protection but a sure way to separate the contaminated ingots.

Look, the .50 cal. ML has approximately .44 mag balistics right? I shoot a .300 weatherby mag over a chrono regularly at 15'. My chrono does have a shield, but it was installed for the higher likelihood of errant handgun bullets. As stated I have shot thousands of rounds from muzzel loaders...
There is no ballistic advantage of pellets vs. loose powder or the substitutes. There is no more risk shooting a muzzel loader over a chrono than any other gun. Gas checks can come loose from cast bullets, you can clip a chrono with a misplaced .22. The chances of a sabot comming loose from a...
15' from the muzzel is pretty much standard for most rifles of heavy caliber due to muzzel blast. Been chronographing muzzel loaders of all types since the early eighties. You can kill a chrono with a .22 or a pellet rifle if you're stupid, I have examlpes.
Proper alloy of the cast bullets and fit are important. Bullets should be at least .001" over groove dimension. Totally remove any traces of copper from your bore an keep loads in line with the alloy of the bullets and all should be fine.

Pure or near pure lead is much desired by the black powder crowd and worth more that antimony alloys. I would be swaping the stuff and ending up with more casting material.
I see alot about keeping velocity low for cast in .357...Truth is if the dimensions in the gun are right, a proper sized 15 bhn air cooled, gas checked cast bullet can be pushed to jacketed velocities with no leading.
The key is proper bullet hardness, size and lube.
Ha!! I got two all expenses paid vacations there once, back to back. Didn't even have to pay the airfare. Enjoy the trip, but if want to keep something don't take your eyes off it.
That is impressive, to get a working knowledge of all the princibles, the quirks of each caliber and a total understanding of balistics and all the information in the balistic tables from reading one book.
I'm not that quick, only been at it for thirty years and only load 24 calibers. I can't...
To be clear, a cast bullet the proper alloy and the proper size with a proper load will not lead in any gun, even rifle. An undersized bullet or to hard a bullet, or the wrong load will lead any gun, even a 1911.
Copper or more correctly gliding metal bullets do indeed foul a barrel, that is...
More consistant than the Bullseye crowd are getting with cast? Or the shooters in the USPSA, Steel Cup, Masters or Bianchi Cup?
With a properly tuned load you do have to clean the powder/primer residue from tha action of the gun every thousand rounds or so, but a good cast load leaves no lead...
