May I suggest dropin' 'em in the chamber before you full length size. Set the dies up so you only size the top 1/2" or so of the case. Ain't no need to full length size the brass, after being fired once it just ain't gonna streach that much any more, unless you full length size it again. That Starline brass is good stuff, I've been shooting the same hundred cases I bought for my 44 2 years ago. Mind you I ain't pushing full house loads, but 40 + loadings without losing a case is not bad at all.
