I don't know about the 200 but I load the 180 TSX with 73.5 grain of IMR 7828 on Winchester Brass and Federal 215M primer. I'm averaging 3,000 fps from my Model 70 Laredo LRH. Accuracy is 3/4" @ 100 yards 3 shot group. I haven't really tested this load on games (been having a ball with my 308 lately)and field shooting were limited to 250 yards. What I like about TSX is that, I can attain 3000 fps with only 73.5 grain of IMR 7828 and to top it off, I gain 3 MOA of elevation from my scope when compared with 180 grain Hornady BTSP, the old standby load for this rifle. Not that I needed it - my Leupold Tactical has ample elevation to get me to 1200 yards - but it's comforting to know that I got that extra MOA. I have read that Factory published BC on the TSX were overated. I have a friend who use this bullet on his 308 and swears by them. I believed he use the 168 and he told me that the BC is right on the money. I will find out for myself. RJ
