I picked up a TC Triumph over the winter and finally got a chance to shoot it over the weekend, it was pretty cool. I started out with some ball ammo and 80 G of Blackthorne and found I was on the paper at 50 yards, not a great group and maybe thats normal for ball ammo. Then switched to some Hornady 250 SST low drag and immediately got a 1.5" group.....I was stoked....!
Then moved the target out to 100 yards and was ~ 16" low (still using 80g), I bumped the charge up to 110g and POI came up 10"...cool...!
Then used 120g and POI raised another couple of inches.... I was still ~3" low...
Then the wind blew my target backstop down and I was done for the day...
I think I will sight in for 100yds and experiment with some different bullets/charges.... The choices are considerable.. wondering what others have done here. What works? what doesn't? is every gun a little different?
Anyone have any experience with THOR bullets?
