 Anyone out there doing powder coat bullets. I just started and hope to get out to the range this week to test some. I was using the Hi-Tech coated bullets from Chey Cast and they worked well. Normally I shot slightly oversized lead in my .45 and 9mm, .452 in my .45 and .358 in my 9mm.. Is this still a good idea with powder coated or should I lean more to actual barrel slugged diameter. |

Baking it on or using a tumbler? Baking, 20 minutes, pretty easy process actually. Going to try and hit the range tomorrow, anxious to try them out. I sure don’t miss lubing bullets. |

I am not an expert in this area. I have been using a .357 Lee sizer die, that is actually .3575, with both Hi-Teck style and regular automotive type powder coating. Same bullet size I used with old lube groove style as well. I don't see any reason to drop down in size. My opinion is that the powder coat bullets cause less friction than traditional lube. This is based on amount of pressure it took to push them through the sizer die.

Had a chance to play at the range this week with some test loads in 9mm and .45 acp. Powder coated .45 sized to .451, exact bore of my 1911. Accuracy was great, velocity was almost exactly the same with a load of WW231. 9mm load using .358 sized 125 gr with my auto comp powder was a disaster. 30 rounds shot in 5 round groups spread out to 8” with two keyholed rounds. Changed OAL out a bit and sized bullets down to .3565, same powder charge, groups improved to just under 2.5” at 20 yards. Satisfied with these 9mm results, still not quite as good as load with extreme plated bullets but good enough. Powder coated .45 loads good enough for matches. Sure like the absence of lube..
