I purchased two cases of the CMP Eley Standard ammo. ($352.00 shipped each) I and three of my fellow smallbore prone shooters have been trying it. Lets start out with the test people. Three active NRA Smallbore prone masters, one Expert about to be reclassified master.
The ammo when weighed, varies between 51.6 grains to 53.1 grains (over 200 weighed) with the majority running 52.3 ~ 52.8. At the range, it shoots quite well with occasional flyers, left, right & low. No misfires thus far with over 1000 fired. As practice ammo for serious prone shooters it is excellent and very reasonably priced. When segregated by weight + / - 0.2 grains it will hold the X ring at 50 meters almost all the time but it will yield an occasional 9. When not segregated by weight, it will hold the 10 ring with occasional loose 9. Overall, It is very worthwhile ammo when used as practice.
