I have shot about 10K rounds of Norma “range and training” 124 9mm ball in the past 10 months- it is generally very good, reasonably priced, and reasonably clean with an average amount of carbon in the cases and in the pistol after an average USPSA or SCSA match.
However, I’ve never seen anything quite like this- the last two cases of Norma 124 “Range and Training” I’ve shot have been producing practically zero residue in my pistols, and the cases literally look like they came out of a tumbler. 2” groups off the bench at 25 yards, no change to zero from previous lots, and practically no flash. Just super-clean.
I would love to know what powder is doing this, or what they changed- I’ve never found any other ammo with this characteristic.
