Just to show how fickle some rifles can be, got finished wringing out the Triumph for my step sister
Ended up with the green hornady sabots, hornady 240 XTPS and 2 pellet 777 (100 gr) with 777 primers. All into one hole repeatedly at 100 (4x at least). Had to swab between shots too and then fire a primer before loading.
Tried at least 10 other bullets/sbots and all of the MMP sabots, CCI, Win and Rem primers and best other group was about 1.5 inches with the 240 XTP and black MMP sabots for tight bores and loose 777 powder with 777 primer.
If did not like white hots, blackhorn, pyrodex powders at all.
Honestly was amazed that the gun like the pellets over Blackhorn or loose 777 but it did.
