Fastest you've pushed powder coat

[nhyrum]

What's the fastest any of you have pushed a POWDER COATED 180 grain lead bullet? Do you think 1400/1500 fps would be attainable? I'm not looking for data,  but a starting place would be nice.

There are guys running PC bullets through rifles over those velocities...

Do you think it would be possible with 5" pistol in the nuclear zone?

Nothing about powder coating enables higher velocities at safe pressures.  Can't do it with a 180 grain with a safe load.

Sure. But I've noticed PC is faster than traditional lube(by a little, PC was about 15-20 fps faster, same bullet, same load) but, could it be pushed to jacketed velocities(pressure is more important than velocity really) I would think so, I've run pc'd in my 454 without a check and they seem to do OK. But those, I usually check, PC and lube.

I will say I have shot my plain cast bullets over those speeds but the 180 grain cast and lubed 10mm I shoot them at 1275 and the 200 grain at 1200 with out issues.
From the 9x25 I see 1750 - 1800 fps from my cast bullets lubed with Carnauba Red lube from White Label...

PC will do well, if done right, but the velocity from standard 10mm 4.5" of 5" barrels would be about the same where as longer barrels could yield higher velocities with the same loads.

Slight deviation, but relevant: Does powder coating change velocities significantly compared to lube if the round is shot through a longer barrel? Would a PCC benefit from powder coated bullets more significantly than a pistol?

I would think so. The bullet is more slippery so it would accelerate faster. It's got more time in the barrel so the acceleration curves have more time to deviate. I don't have a pcc, or cast for rifle, so I've got no way to test.

I've thought about using cast in my 9x25, but the comp leading up worries me with traditional lube. PC should help. Now go get a 115 grain mould for it

WE plink with just about everything. From a 22LR to the 458 Win Mag(makes a hellava turtle gun). I've been loading a light weight lead bullet the 30-30s for decades. I bought some Acme coated bullets from Graf thinking clean up would be a lot easier, I was right. No grease, wax, crap to gum up the works. I'm loading 35grs H335 under a 135gr coated bullet and that gets me right at 2500'ps. Barrels after several hundred rounds in an afternoon are near spotless. I'll never shoot another bare lead bullet again. I have coated bullets for the 10mm, 180gr from Missouri Bullet Co. that I've loaded to 1300'ps. They shoot as good as any jacketed bullet and leave the gun clean. The best news, no smoke like you get from a bare lead bullet. Can't be real dandy breathing in the smoke from the lead bullets. There's a reason indoor shooting ranges do not allow lead bullets and it's called air pollution from microscopic lead in the air.

I haven't really pushed my 180 PC bullets that hard, but my 203 gr WFN plain base go up to 1250 fps from the 4.6" barrel. No leading. I have a 209 gr WFNGC that pushes 1215 fps.

Very good groups and no leading. Many people are running rifle velocities with PC.

A properly cured and fitted PC bullet might or might not need a GC at 14-1500 fps. Fit is king. I'd try it and see how it goes. Best case is no GC is needed since they cost more and take more steps to make.

I have pushed 190 grain GC cast bullets in excess of 1400 fps out of a 6" KKM barrel. Using Longshot powder, no issues.
