I just traded away a bunch of my good 30 rounders for another safe and sold the rest or traded for 20 rounders.
The bandoleers that came with the 5.56 ammo from Vietnam holds the 20 round mags. I just fell more comfortable with them, and besides, it's getting damn expensive to feed 20 rounders, never mind 30s and 40s.
When I want to do shooting for accuracy, not for bang and boom, I use the neutered Mass 10 round mags from Bushmaster and take my time. Stopping to refill the mags and shoooting the crap with someone is part of the fun.
