You will like your Triumph. Mine shoots good with everthing I've put through it. I settled on 300gn bullets and 110gnv Blackhorn 209. I like the .458 Remington HP, BCR sabots.... .458 Barnes Originals, BCR sabots.... .452 XTP, RCR sabots, all 300 gns. With 110 gnv BH they chrono about 1875fps. When I first got my Triumph I shot a couple 200yd groups right at 1 1/2" with the Remingtons and 110 gnv BH. Good luck and have fun.

You'll like that 2-7x 32 Bushnell also . My son has one on his Optima. It's as clear as it gets.
