Yes, it is worth every penny.
Crack, BOOM. One 1lb'er in front of a steel silloutte target at 300 yards sounds just like a lightning strike.
Just don't put it too close to a target stand unless you are finished using it. Not because it will be knocked down, but because it will obliterate it. One OSB stand met its demise that way.
It will be missed. However, it saved us having the throw it away because there was nothing left of it or the targets that were on it.
A friend arrived late, so we told him his target was all setup and he should just start shooting. He didn't know that there was a jar set right behind the target on a cross support. 3 shots into it, his target and entire stand were no more. "What the fuck was that?!"
Lesson, don't shoot at targets other people setup for you.
