I and several of my friends have tried and use this ammo. All of the friends are master Smallbore competitors and one is a three time olympian shooter. We have found that the CMP ammo WHEN IT IS SEGREGATED BY WEIGHT, is excellent practice ammo. We segregate by groups of 0.2 grains. That is, the variations of that ammo run from (with some anomalies) about 51.2 grains through, 54.3 grains, with the majority running in the 51.8 ~ 52.9 range. When segregated in groups such as 51.2 ~ 51.3 gr or 52.6 ~ 52.7 etc and the segregated lots are used together, the results are excellent. Some rifles will like the groups of a certain range, but overall, the results are quite good. Do I use it for matches? NO, there will be within the segregated lots an occasional flyer just like is gotten with SK or Eley higher grade ammo. But at less than half the cost. Overall the stuff WHEN SEGREGATED BY WEIGHT shoots extremely well and well beyond its price point.
