For obvious reasons (though I have handloaded primed .22 WMR hulls).
.38 Special -
I've gone through 50 rounds in 2 years...
Crankylove gave me some old RCBS dies, and I have brass and bullets. But, I don't shoot it enough to really care.
A 25-50% case loss rate pretty much negates any "savings" achieved by handloading. (SKS + forward/vertical ejection + grass/gravel/sagebrush = bye bye brass)
