I have heard some good things about Center - X for a mid priced product. Has anyone on the board used it?
Have shot a lot of it, both off the shelf in training and competition and testing with Lapua themselves. It can be really, really good. It can also be really, really poor. If you're buying blind, it's a lottery. I had a batch my club got in. Was shooting fairly decently with it. Managed a 589, which is solid for me, but when I tested with Lapua, it grouped 18.4mm for ten shots. Tight central group with radiating fliers. I tested a bunch of different batches of Centre-X that gave tighter and more regular groups, and some Midas+ that did better too. There was a lot of overlap between the better Centre-X groups and the weaker Midas+ groups. In the end I got a batch of Midas+ that shot 12.3mm and 13.7mm from the test rig. My scores have been shooting up since. It may not be feasible to test from a specially built rig, or get to the factories to do it, but if you're good enough to use even mid-priced ammo and benefit noticeably from it, you're good enough to want to test reasonably extensively, in my opinion, whether that's at a factory or from prone off sandbags with a scope or whatever your preference is. You certainly can't just buy more expensive ammo and hope to be competitive. I got batches of both Centre-X and Midas+ that would not hold the ten ring from my gun. They could shoot like a house on fire for you, but for me, they weren't worth dirt.
