So, my Triumph loved the 250gr TEz over 100grs BH209. Excellent groups (1" or less ), but I'm out so I've switched to the 300gr, .430 xtp's, cause i have them and if I load them with 100-110grs of Bh209 I can get those same groups. But, dropping down to 80grs only sacrifices 1/2" at 100yds. Dead dear regardless. Also along time since i've shot a deer past 100yds, 75 for that matter.

so, why so much powder?
