There are several bullets that hold up to WSM speeds that don't cost an arm and a leg. Gamekings are not expensive at all, I just bought a box of 100 for $26. I have yet to see or even hear about one of them coming apart, Midway USA has them at 5 stars in almost every weight and every caliber. My accubonds are really nice but cost twice as much, and partitions are $31 for 50!
