I just finished my first case and have just received 2 more cases (my yearly allotment). My CZ455 absolutely loves it. A couple of friends who shoot Ruger Precision Rimfires also have gotten very good results from it. Every 80-100 rounds or so, you may get an odd round that is a little bit hot or cold in relation to the rest. But overall, it seems to consistently produce a single digit SD and remain relatively accurate out to 400 yards. If you are expecting Eley TENEX consistency and performance, you might be disappointed. But for 7 cents a round (as opposed to 35-40 cents per round), it is really good ammo, provided that your rifle likes it.
