I kind of like the tens. I have 2 610s a 4" and a 3", both have great actions. I also have a 1026 and a 1076, both of which are quite accurate. I think that the 10mm may be the only semi auto round that is up to large animal defense. I say this primarily because I can get really great penetration with some of the botique rounds, particularly from Buffalo Bore and Georgia Arms. With a 200-220 hard cast flat point you are getting the same or better penetration as a 41 or 44 magnum, and for large animals penetration is the name of the game. I would say the same of a jacketed flat point moving a the same velocity. I know that if one uses an expanding slug you are not going to compete with the big slugs from the magnums, but I am not talking about hunting, I am talking defense which means a central nervous system hit, which means penetration into the brain pan or the spine.
I will probably start packing it in the woods after I perfect my small point hit ability with probably the 1026, I kind of like the longer barrel.
