Buffalo Bore does have some competition besides Garrett. There's Grizzly Ammo (hardcast only) and Doubletap. In my view neither are quite as good but they're not at all bad.
I blew up a bowling ball with a Doubletap-loaded Gold Dot 125gr high speed variant slug in 357Magnum. Split it in half, turned out to be about 1" thick plastic surrounding concrete, or what looked a lot like it. Sent fist-size pieces of the core back past my feet and I was a good 20 paces out.
The guy who owned the ex-ball said he'd never seen that sort of action out of a handgun on one of those things.
Doubletap is cheaper but some of their advertised speeds HAVE come up short in tests. Not as often, but they don't have the same rep Tim at Buffbore does (or Garrett, the only other small ammo house I know of that exceeds BuffBore in some loads - they have a much narrower product line though).
