I've shot Precision Rifle's "Dead Center" bullets - they are similar to the "QT's" you are looking at, but not identical. My impression is that they are very well-made bullets and extremely accurate, at least out of my ML. Personally, after shooting them at a couple range sessions I came away with a very high opinion of them. I never had a chance to test them out on game, though. I don't shoot them now because they are too expensive - there are other good bullets out there for less money. However, if I could find a really good deal on some, I probably would pick them up.
