I personally have never owned that rifle, but I find very few T/C rifles low quality. Their barrels are top of the line, and while (from what I have read) the Z5 had some stock issues with being not as good as the other rifles in the T/C line, for the price it was not meant to be. It was produced to be a low end high quality hunting rifle. It looks like a great shooter from your targets. I make my judgement on any rifle, one they are in my hand and I have a chance to range test them. It looks like you have a good rifle.
