Under cooked PC


Staff member
Has anyone had experience with shooting bullets with under cooked PC?

What are the signs? Did you notice a specific fouling? How did you remove the fouling?

While shooting at the indoor range I occasionally got a hint of a burnt plastic odor. The barrel was leaded a bit and had some fouling that was a real bear to remove.

Bullets were baked for 30 min at 400 F. Oven has a PID and was already at temp when bullets were placed inside. This is with powder from Smoke.

Leading was somewhat my fault. I loaded this ammo and didn’t realize until I tried to load it in a magazine that the seating was too long. I repeated deeper but this scraped the sides of the bullets a little.

the cut in it may have been your problem.
you still have to play by the cast bullet rules.

I figured that cut would give me grief.
And I have another 100 rounds of them....

Might try wiping the front band with BLL (or alox). I just remove the bell, no crimp in anything, seating deeper sometimes does break the PC - leading is minor (for me) and shooting a couple jax usually removes any 'stuff' in the barrel.

Having been interested in PC a read the first 3600 posts in the HTC thread over there ..........
The under done HiTek will wash a barrel and require efforts rivaling lapping to get it out or a $40 AU/litre solvent will wipe it out with a nominal soak/wipe/soak/wipe thing .
I don't know about the rest of the PC stuff . If paint won't stick PC shouldn't but I don't know really .

If you indeed cooked @ 400 degrees for 30 minutes, I can't see how it was undercooked. I cook for 20 min @400 and thought I might drop back to 15 min. They pass the smash test and that means they're good to go in my book.

Somewhere the other day I read a post where a guy was testing this with MEK on a rag and wiping bullet testing for color transfer. Smash test seems to be the most acceptable way of testing. Looking for a definitive source of information about PC but still haven't seemed to find it yet.

Cured PC is removed with MEK or acetone, possibly others. HiTek may wash some color off even when cooked correctly - just use the smash test.
