Many moons ago I purchased 1,000 RCBS 165 Sil bullets, cast, lubed and GC. Trouble is they are 0.309" and do not shoot well in my 30 caliber Springfields, M1917, Garand etc. The lube is blue. The question is can these be powder coated in the hope of gaining an additional 0.001-0.002"? My gut tells me the I would have to remove the lube first then try PC.

Thanks,

Dave

Dave: Your gut feeling is correct. Any trace of the bullet lube will destroy any chance of  the coating adhering to the bullet. Another problem you will encounter is that the bullets are gas checked and any solvent used to clean off the lube will seep under the check and when the bullets are placed in the four hundred degree over it will sound like popcorn as the checks blow off. (please don't ask how I know) even steam from water will do this if you heat treat the bullets to harden them before coating. I would say the best bet is to find another rifle to shoot these bullets up. A rifle that they fit. Gp

Probably would not get the flying GC's past Winewoman so that's out. I do have a couple of 308's (Ishapore 2A and a re-bareled Kar98) that could be tight enough but I have not tried them yet.

I tried that over some LLA coated bullets on something like my third or fourth attempt at PCing.  First I tried boiling the lube off and that just didn't work very well.  I figured  maybe it was good enough though and coated about 200.  When they were done they were just ugly.  Lumpy and bumpy and you could scrape the coatings off in places with your fingernail.  Simply turned them back into melting pot material.  However, laquer thinner turned out to be real good at removing the alox prior to coating.

For cleaning bullets before coating, I think acetone works the best but be careful and wear quality gloves. That stuff is hard on your liver.  Gp
