Is gamo spinner targets to much for our rifles? I just picked up some thinking it would be alright for my avenger at 30yards or should I build a box around it because I do have neighbors on both sides?
That helps a great deal. After seen your photos sorry for saying gamo but the ones you use are what I got from Walmart for 11 bucks. I was thinking of placing logs on each side to prevent fragments flying off behind it is a field. Even though the would have to come off prefect to get a neighbors house because they are forward some n would not be at the sides of the targetNot sure I understand what you're asking about a spinner target being too much? If you are referring to this spinner Target from Gamo, I think you got it the other way around - these targets are fairly lightweight and I have found that a powerful air gun will damage them. In other words, the energy from the pellet is too much for this particular target unless you are using a lower powered 177 or 22 caliber. A 22 caliber air gun making 25 to 30 ft lb will damage this target. You can see in the picture how lightweight and thin the steel paddles are. I have noticed damage on the one that I tried.
And if you shoot at the top horizontal plane spinner, it is very possible for paddles that are at an angle to you, to throw a ricochet off to the side. This can also happen if you hit part of the spindle. This is one reason why steel targets are not allowed on many ranges. So yes you do have to have a backstop of some sort and maybe something enclosed on three sides to be absolutely sure you don't send something toward the neighbors.

My favorite targets are these inexpensive Crosman steel spinners. They are much heavier steel and they hold up to 25 caliber and 40 foot pounds no problem:

I have multiple sets and place them at whatever range I want to practice at or collect trajectory information for my range card and use cheap white spray paint to renew the surfaces. When I want to confirm the trajectory for a new setup, I have a set of four or five and I place them at every 5 yards to collect my trajectory / holdover data and coordinate that with results from my ballistics app such as Strelok Pro.
Warning: Steel spinner targets such as these that use a paddle that has a half twist to allow it to hang on a cross rod WILL cause sideways ricochets if a shot hits the twisted area and gets redirected!
I like to place mine at the base of a tree that is wider than the spinner set, to intercept misses or ricochets.
Hope this helps. GL,
