Testing was done from a rest at 10 yards. From a Umarex Fusion 10-shot groups have gone to just over 3/8" CTC. Best lead-free pellet tried to date, but not the best pellet for that rifle. Today the test was the first 10 pellets out of a Crosman 2250 with 18" barrel. Last pellets used in the 2250 before today's test were Air Arms Diabolo Heavy. Did not clean the barrel first. Did not condition the barrel with preliminary shots with the GTO. Just sat down and fired 10 shots. First 10-shot group just over 1/4" CTC. Comparable to the Air Arms Heavy. Very surprised and pleased by the performance of the GTO. Did not think it was possible with lead-free.
ProsNo lead. Surprisingly good accuracy at 10 yards. Better than any lead wadcutter I have tried.
