I have not used the TTSX, but have shot a lot of 210 TSX with 75 gr of RL19 for 2930 fps in my old FN actioned rifle. I have shot caribou, bear, etc. with it and you can't recover a bullet. It will quite often (if the shooter is having a good day) group into an inch at 200 yards.
A shot not taken is always a miss

Everyone praises RL19 in the 338. I have been loading for a friends 338 and the best group I have found for it so far was with IMR4350. That was with 215 grain Sierra's. I am done trying any more powders myself as the trigger time with that caliber is brutal . I figure 3/4" groups at 100 yard is more than adequate for it anyway since he will only be shooting 80 pound whitetails with it .
I am a 338 win Mag nut and own 3 rifle in that cal. I have found that 77 gr Rl 19 with a 210 Barnes TSX workes awesome...I use a 210primer..This combo produces .50-.75 groups all day long for me.
