Annealed some 3-4x fired 284 brass. 6.5 - 7 sec in single flame gas torch, all cases on next firing came out with split necks ? Too much heat ? Or not enough ?
Cases not annealed no cracks or splits.
Have annealed plenty of other brass using something around 6 - 7 sec in flame & have not seen thus before ?
Wot ya reckon ?
