Just for myself, the SST/SW series is way down the list of my bullets of choice, but if you are going to try to extend your range as far as you indicate they might be OK. I am hoping that if you are hoping to shoot accurately @200 and beyond you get a lot of practice in. There are a lot of varibles in shooting a ML and as you extend the range the varible get a whole lot bigger.
I would think if you want to shoot that type range you might look into a 200 grain SW, assuming you are after whitetail. We have a shooter on this board Spaniel - that does a lot of this type shooting (actual hunting at these ranges) and has spent a lot of hours working the kinks out. Another shooter Lemoyne shoots a lot at those ranges but I don't not think he hunts at those ranges. Those two are probably your best resource for shoot consistenty at 200 and beyond. I'd drop either one of them a PM - they both love to help.
Most of the rest of use a just regular shooter/hunters - bet my average shot is 60 yards and my long shots 150 with my max limitation set by me is @ the 200 yard mark - well at least with a ML.
I see no need for pointy bullets with my max range set @ 200 so I still use regular old fashioned Noslers for hunting - although this year I am making a switch to the Lehigh line of bullets 200 grain for witetail and .458/277 grain for elk.
Your biggest search right now will not really be which bullet to shoot but which sabot you can shoot. TC bores can come very tight to very normal. When I first got my Triumph - I could not get anything to load well (smoothly). It did take some elbow grease and work on the bore - but now I am able to shoot what I call the normal sabots, MMP HPH-24, Harvester Short Blacks, even the MMP Blue 40/50 and the Orange .4587-.458/50.
Good luck with your new gun - you got a goot one....
