"already we are seeing "match" or "target" ammo that is the same crap they were selling, but with less powder to slow it down to "target velocity" and no improvement to the shot-to-shot quality control".
I'm curious, what ammo would that be?
Last year I was doing
lots of weighing and measuring of ammo. (Busman's holiday - SPC was a big part of my career at Zeiss.)
I rate any ammo as "good" if I can get 45 out of 50 in a box to be +/- 0.1 grains weight on a Pact BBKII digital scale. (i.e., say, 53.0 grains to 53.2 grains. I'm offering weight as a proxy for overall process control, since it's easy to measure.
My considered answer to the question is: Every American brand except Federal UM22 and 922a, and that may not actually be American.
The only US made "match" ammo I've had that was ever
really good was the Federal UM1, now long out of print. Federal 922a and UM22 tested about the same statistically (weight variance) as Wolf Match. (I've read a rumor that it actually is made on the same mfg. lines in Germany.) Typically only one or two out of 50 would exceed 0.1 grains variance from average.
Winchester T-22 "Target" I quit even measuring. No better than their bulk ammo. Ditto Federal 711 "Gold Medal".
Three lots of CCI standard velocity looked OK, but I found two more lots that were less than. But it's not marketed as "match" ammo, although I see some folks using it.
Interestingly CCI MinMags had pretty fair numbers for bulk ammo, as did Auto Match. (Better than 45 pieces within +/-0.2 grains for a whole box.) Not really "match grade" by any means, but a whole lot better than Remington Thunderduds. (+/- 1.5 grains, sometimes more!)
By comparison. the high grade Eley I can't get
any weight variance at all - my scale only resolves to 0.1 grains. 100% of five boxes from two lots were all dead on.
