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.
