I've had a TI Tracker in 41 Mag for about 7 years, and I'll share my experiences with you.
The best combo I found for my gun was the 210 XTP and H110. This bullet shot well, performed well on the small game (rabits, porcupines, and raccoons) I shot with it, and is a good all round load. The 170 Sierra is a beautiful deffensive load for 2 legged predators, but not so good for anything you want to eat. It expands a little too well. The 250gr Cast Core factory ammo DOES jump crimp after 2 shots. The same bullet in comparable hand loads doesn't move as much, but you still want to keep an eye on them. I couldn't get the accuracy I wanted from the heavy bullets out of my gun. You might have better luck. The heavier bullets don't fit in the cylinder, so I just didn't bother. The load I shoot the most of is a 215gr cast bullet and 5.7gr of Trail Boss. It works great on small game, and is just plain fun to shoot.
As for the gun itself, I have always had a love/hate relationship with it. It has never shot as well as I would like it to, but that was offset by the light weight. The fit and finish of the gun isn't bad, but it also isn't great. There are some rough spots, and the chambers need to be polished. Mine gives sticky extraction with almost any load, even the super light loads with Trail Boss powder. It's not like I need to force the brass out of the cylinder, they just don't slide out like they do on my other revolvers. It's also hard/expensive to find replacement grips for them. I wanted to get some wood grips to use the gun for CC, but I'm not sure that the gun is worth a $150 set of grips to me. My biggest complaint is the porting. With lead bullets it's just a pain to clean them after a day of shooting.
At this point, I'm selling TI Tracker as soon as my buddy gets his tax return. I like the gun, but I just don't love the gun. If S&W had offered the Scandium 357PD (the scandium 41 mag) at the time, I probably would have bought that gun instead.
Good luck with yours. They are a dream to carry in the woods. I have actually forgotten I had mine on before.
