Xpert stuff is crap !!
I tried a box of those Xpert .22s as a possible rplacement for the Dynapoints. The Xperts produced more of a "pattern" than a "group". At first, I thought my scope took a jolt, because at 40 yards, shooting at an 11" X 14" target, only 2 of 10 shots were on the paper !!!! After checking out the scope, I ran a few Dynapoints through the gun, and then tried the target again - all ten were well within the 1.5" center dot.
I have not found a gun yet that the Xpert stuff shoots well from, whereas, the Dynapoints shot well in everything I tried them in.
I thought this might have been a fluke, but in comparing notes at a recent gun show, other shooters shared similar experiences with the Xpert ammo. I guess I'll have to try the Federal bulk stuff eventually.
