Hi I have the leshiy in 22 it was very accurate , I then got the longer barrel and huma regulator for higher shot count and more power if I need it as it .I love the way it shoots now ,I did a trigger mod and put wood grips , I can say i have about 15,000 pellets threw mine and I never even had so much as a breech seal go ,I can take it apart to clean in minutes and it is very rugged , as far as accuracy I found with mine My most accuracy with jsb pellets is 27fpe and i run my regulator at 91 bar . ok If I wanted to I can set reg at 150 bar and crank up hst and get prob 40s fpe , but with me anyway , I cant get groups as tight as the harmonics play a roll in it .
As far as noise , when it is set like mine is all I hear is the hammer hit the valve so quiet , and it is repeatable I know from 300 bar to 90 bar , I can hold dead on at 50 yards and 100 yards is 4.6 mils and this caliber is accurate at 100 yards , at 150 yards the drop is like almost 12 mils so it becomes a bit more difficult .
I have not tried any other calibers , I did buy an adapter for a moderator I was going to make a slug barrel in a different caliber but never got around to do it with the other guns I been shooting at the time .
