My first use of these were in .22 caliber in a different rifle (break barrel, spring piston) and I found terrible accuracy. Now, in .177 caliber and a different rifle (semi-auto, fixed barrel, CO2 fired), I am starting to think clover leaf results at 10M might just be in my future! It took over 30 rounds to get there but after the first 30 round mag the shots came on target nicely. I can't explain why but maybe I would find better accuracy in the .22 version after more shots fired too.
ProsLegal for California hunting or clearing property of nuisance, non-game animals, i.e. ground squirrels.
ConsI don't see that there is much surface contact with the rifling with this design. Maybe that's why it took over 30 shots to show some accuracy.
Best UsesTarget shooting. The head design leaves perfectly round holes in paper. Looks like I took a paper hole punch to the range with me.

.177 GTO - best lead-free to date
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.
