CenterX may well be the best bang for the buck.
After getting my CZ455 Varmint bedded I tried Eley TEAM, MATCH and TENEX. The best group at 50 yards was .70.
Next time out I used CenterX from a clean cold barrel and the first group was 0.26. Since then I have shot a 0.45 at 100 yards and today shot two different lots that were under 1" at 100.
Also today with the CZ455 American, CCI MiniMags were about 6". Blazers about 3". CenterX first shot was about 3" low and left. Using a hold on the opposite side of the first shot . . . 4 shots in the ten ring at 100 yards.
I think I will get the American Bedded and Pillared too at least then the torque on the action screws will be consistent. I guess the gophers will have to learn to digest CenterX's.
Keep in mind that Donna at HIRSCH will put together boxes of ammo for testing, and will be able to keep enough set aside that you can order a few bricks or a case. Just don't waste any time getting your testing done.
Buying TENEX at $20+ for 50 rounds is a good deal if it works in your rifle versus paying $50 for a brick that doesn't and may never work. Buying CenterX at $12 for 50 is a better deal. There is still some TEAM to be had, and the new EDGE has shown promise out of my BSA. with velocities from 1066 - 1081.
