I did some ammo testing recently as I was finding the Eley subs had become inconsistent.
As above I found cci’s printing fantastic groups at 50 yards. But when I pushed the range to 80 yards the target would look like it had been hit with a 410.
I settled on Eley Edge as they were printing consistent 1 inch groups at 100 yards.
This is through a Weihrauch HW60j with a 14 inch barrel.
