Triumph will most likely like 100 gr BH 209, CCI mag primers, TC superglide sabots/250 gr shockwave bullets. This is a tight load in the TC but pretty accurate combination. FG suggests lapping the bore to polish out any areas in-order to ease up the loading pressure required. Congrats on the purchase of the best production line of ML rifles out there! While the Leupold rifleman scope that I installed on my Triumph is not a ML scope I had it and it was new and I think I will get many years of service from it. Time will tell. I still think a 3x9x40 scope is more than ever fully justified for the new long range shooting ML rifles. Again congrats!
