I haven't bought any new Auto Match in seven or eight years, but have a few thousand stashed away. I've found it to be quite good in a semis custom 10-22, a 541-T, and a repro 52. It seems to shoot as well as anything costing less than $8 per box at fifty yards with the exception of the occasional flier. When I happen to get five good ones in a row, groups will often be less that a half inch.
I've avoided buying any of the new stuff because I already have plenty, because the price is often too high, and because of the rumored drop in quality.
