Definitely Starline Brass, with-out a doubt, absolutely bestest available... (This has nothing to do with the fact that Starline is made in Missouri and the more they sell, the more they pay in taxes, and the more they pay in taxes, the less the governor will want from me.
)
The only brass I have had any trouble with is some very old nickle plated brass. I am in the process of reloading some .357 Mag now and just a quick peek of a few pieces show Winchester, R-P, W-W Super, Starline, Federal and PMG.
All of this batch of brass is only on the eighth reloading and I expect to get at least eight more out of them before I start seeing problems with the occasional cracked pieces.
