I’ve been long planning a broad test of various budget 22LR ammo to see which groups best in my factory CZ457 rifle. Aguila Super Extra comes in two varieties: High Velocity a Copper Plate version and Standard a lead round nose. Likewise, CCI comes in Mini-Mag, a copper-plated, high-velocity round, and Standard, which is a sub-sonic lead round nose. Both of these rimfire bullets have a light wax coating.
I expected CCI to group better at 100 yards. Because Aguila’s stated muzzle velocity is slighly faster than the speed of sound, common wisdom states that it should be slightly unstable as the round slows down below the speed of sound. Overall CCI Standard had slightly tighter groups, but at the start of my testing, that wasn’t the case. Aguila wasn’t too far behind CCI in performance but where it does excel is in price, at 30%-50% less than CCI Standard.
