I have a M1A1 Thompson and I always looked for boxes of 50 rd GI, 45 acp ammo to run through in the past and which usually ran much cheaper then commercial ammo and I used to buy it for $8-10 a box, then it went to $15-$20 a box or so. I haven't shot the Thompson for a good number of years so I haven't been looking to buy any ammo for it and what I already accumulated I shoot in my 1911 pistol once in a while.
The last time I happen to notice some boxes of 45acp ammo for sale at a shows they were priced at $35 and even $40 a box. Funny how your mind works, even though I haven't bought the ammo for a long while, but because of past habit, I would still would focus on those boxes of GI ammo at shows.
Anyway the question, I spotted this box of box of 1990 Match ammo all by it self on a table at a show priced at $25 which I though was a decent price from what I've been seeing, and which I was able to buy for $20.
Ok, having said all this, my question is, is there a big different in between the match 45 acp ammo over the regular ammo? I imagine closer tolerances. Do they do a special more closer watched run of them? Just curious, Ray

Most uniform brass they have and the powder that develops the best accuracy with the bullet being used. Pretty much the same in Israel as here.

There is very little difference between match and ball. In ball ammo the primer is crimped match ball is not. From the line drawing it appears the extractor cut is different and the weight listed for ball is 331gr where the match is listed as 334gr. See 8-13 on page 98 and 8-15 on page 100 of TM43-0001-27.

The match ammo was like the NM pistols in that it was in a constant state of improvement. Bullets were tested, and the lots that showed the best accuracy were chosen as were the lots of powder. In one run they produced 750,000 rounds of match ammunition in one continuous run.
