Well you hear good and bad about just about every firearm. In our sport we treat our firearms in ways that they were not designed. I've used the Thunderbolt for 3 years as my main match rifle, it had a few hicc-ups when I first got it, mainly me learning what it wants as far as how to work it. I've taken speed rifle with it a few times, and not just at dump targets. I could just be one of the lucky ones, or it could be that I shoot factory type loads and 250 grn. bullits.
