I know Dick Thompson and Jeff Hoover have been trying this pretty extensively over the last year or so and have had similar experiences. According to them they have found no real draw backs to it beyond getting over the nonlead looking bullets. Hoover has even run them in his rifles fairly fast, 2200fps ish will no ill effects beyond smaller groups and faster velocities. Hoover has offered to coat a batch of bullets for me and then to return them for testing but I don't have enough unsized bullets that I want to test to try it yet so I need to get the pot heated up I guess.

So far I know of no real draw back to doing this but it will be interesting to see if any come to the surface over the next couple of years. The closest thing I have been told to a negative issue is that in the baking process the bullets all soften to about 10-12 hardness no matter how hard they were when you start. But since hey are powder coated they don't lead he barrels at all so is this really an issue?

Or 'Slowhand' anyway. He had a peanut butter jar full of colorful cartridges last October. I expect he'll be along shortly. If not, I can ping him for his input.

Admittedly an unreasonable bias, but the colors turn me off. If we could come up with a dull silver or a golden copper, I'd give them a whirl. I even have a bit of trouble with the red FTX tips looking like a rack of lipsticks. There's probably a name for this and I'd bet it's hard to pronounce...

do you mean something similar to what these folks make?

I've been buying coated bullets for a year and a half from a commercial seller. Up until recently they were a blue grey, maybe even purple color (of course I'm colorblind) .

I knew at a glance from a distance what they were. Recently they switched to a copper-ish color, now at a glance or from across the room I can't tell what they are, jacketed? Plated? Nope, coated.

Another bother was the chronograph. When I tried the new color I was also trying a new powder. I ran 45 in a row through the chrono of the blue ones and all 45 read. Then I switched to the new color and only about 60% read. ???

I have tried it in a couple of caliber. So far I not really that impressed. The accuracy in my Baer was about 50% larger with the PC bullets over the same bullet lubed normally. One advantage is you can cast a soft plain base HP and not have to worry about leading.

If I ever get some free time I plan on testing them in the 9mm. I have been able to get my 9mm s to shoot with cast but it takes work and some playing around . I am hoping I will see better results with the PC in that platform.
