Just received this today Gamo Shadow Maxxim Tactical .22. Unboxed it, quick function test, scoped it up ( I always use Locktite wicking grade thread locker on all of the mount screws) and off to the range.
This thing is absolutely phenomenal. I was only able to get about 75 shots in today and it sighted beautifully and hit everything I was aiming at. The Gamo scope is pretty good and the trigger is nice as well.
There's a lot more work to be done but this may very well be a new favorite.
PS I was using Benjamin 14.3 gr pellets.
PPS the pellet tin the photo was shot three times consecutively at thirty yards. The soupcan dot at 15, just for fun.
A great little rifle. Nice job Gamo!
