Re: New Brass, .243 Cracked neck
I would vote for a dose of case annealing too. It certainly can't hurt. I bought an older BDL that came with 1,000 or so mixed headstamp brass and a goodly number of it was split at the neck. All of the brass benefitted from annealing.
Just an FYI: I started using the new Hodgdon Superformance powder behind an 80 gr. Barnes TTSX which brought the velocity of that bullet up to just over 3,600 fps with good accuracy (1/2"). Monday night I shot a good boar hog at 165 yards with it and got a complete pass-through, with good expansion and a huge amount of internal damage. I was frankly impressed with how well it performed. The picture shows the exit wound.
