I've shot 200 rounds of Starline and had no issues......but because it drives me nuts, I've gone back and done more brass prep work on the LC brass, I haven't shot it yet, but I did find I wasn't seating/crushing primers and my primers were basically flush (.000) below the case, which was .007ish away from the primer pocket bottom.
Another thing I found was the brass that I had FTF's on, the shoulders were also pushed back .007-.010, after at least two attempts of getting them to ignite. I would not have believed a firing pin would do that, but I've got 15 pieces of brass that all started at .000 and ended at the numbers noted above, which indicates the force of the firing pin went into seating the primers and not setting them off. Hard to believe, but I did dig up a couple of threads where others saw this same thing.
I did a bit a primer pocket uniforming (that is so fun) and bought a FA hand primer that has adjustable depth and I'm now crushing about .006, which should be fully seated. I've got 200 LC prepped in this manner and will load in the next couple weeks and shoot them. The only thing I can fall back on is "stacked tolerances" of a tight chamber, not fully seated primers.....but I don't know. If I shoot and have any FTF, I don't know what to do and will move back to just Starline brass, which makes no sense.
I've stuck with this barrel and Starline because it shoots so damn good, basically .75" groups of whatever bullet throw down it for 10-15 shots, it's a great barrel.
More to follow after I shoot.
