MontanaMan, what year is your FC LC brass marked?
I would load some warmer loads and see if it retains the primers. I'll admit my run in with FC brass was 10 years ago. I bought some new LC brass marked 09 I think and it has been fine.
The stuff that has FC LC on it is 16 & I haven't used it yet but I will be shortly loaded as you've mentioned..........already got around 1,000 rounds of it loaded.
Got a fair amount of 09 too & it does not have FC marking on it & it's been fine for me in both bolt guns & AR's.
After I get in to the 16 stuff here in the next 2-3 months I let you know how it holds up.
