Cool! - vertical grouping in this case, shows a wide velocity spread, shot to shot of some rounds, while the round Ely groups, shows good close velocity readings.

I suspect the Ely ammo will shoot nicely at 50 meters from that rifle.

Burris makes rifle scopes for 22's that have stadia marks or wires that give zeros to 500 yards with particular 22LR ammo. A windless day is advisable for longer than 50 yard shooting with .22's. The width of the above groups shows good wind reading or a lack of wind.
