I shot the TK 2000 today. It is pretty cool for here in hillbilly heaven but I just wanted to shoot it. I loaded up some loads recommended by someone here on HNI. The 110 gr load was an opener or I could say an eye closer. This sucker packs a punch!! The recommended load was using 80 -90 gr of Pyro. I have a 458 Winchester and it ain't got nothing on the TK. I am going to love this sucker.
