It is well known that shiney brass shoots better than grimey brass
Well maybe not, but it looks better
One Distinguished HM, he never cleaned his 308 brass, and never removed the lube. He picked up his M1a brass, rolled the things in a RCBS water soluble saturated towel, added 22 drops of RCBS water soluble, sized the stuff, only trimmed if it felt too long in the die !EEK! I really doubt he ever cleaned his primer pockets. He took his brass an entire shooting season and he won every medal that could be won in CMP competition.
