Thanks guys for the comments. I realize the 15-22 isn't a target rifle. I have three target rifles which are very accurate. The 15-22 is basically a trainer for my AR for manual of arms. I thought it unusually accurate at 25 yds (one hole round groups) but I knew the test of accuracy would show at 50 yards. I was a bit surprised that it shot worse with match ammo than higher grade non-match-ammo. I will compare the Aguila with the Norma TAC and CCI 40gr MM. One inch at 50 yards for 10 rounds is certainty acceptable for a non-match rifle.
