So the Triumph is pretty darn close to the Pro Hunter. Cause I was using 115grains of BH209 and it was giving me 1.5'' group at hundred. I still might try 100grains and just work my way up. Shoot a group of three every 5 grain increment and see what works. I want to stick with the 300 grain XTP, I know that its a heavy bullet. But once it hits a deer, its game over. I use to hunt with a .450 Marlin lever action(Guide Gun). I love that gun, nothing like hear the loud "THWACK" on a deer. Still have the gun, but liking muzzleloading more and more. Wanna buy a flintlock sometime next year. Sorry got of topic. Well I will let you guys know what I find out this weekend.
