TC Triumph?
 

Does anyone have A TC Triumph? If so what powder and round is giving you the most consistant accuracy? Thanks

110 to 120 of BH209 by volume. The harvester sabots (short black) work best for me as well.

90-100 gr Blackhorn or 100 up to 130 gr 777. Barnes T-EZ 250 gr or Scorpion PT Gold 300 gr crush rib sabot

Barnes 250gr TEZ or Hornady FPB, with 90-100 gr of Blackhorn.

I LOVE my TC Triumph! I got my first ML deer last week, a 3 pointer. I've only started ML hunting last year. I have a 3-9X40 Nikon Omega ML scope (Nikoplex reticle) that is awesome as well.

I use:
TC Shockwave 250 gr
Harvester Short Black Sabot
130gr 777 pellets (2x 50gr + 1x30gr)
CCI primers

I could get even greater accuracy if I switch to BlackHorn powder....but she's nearly a tack driver like it is! You'll love your triumph.
One tip---I think I'll start storing mine with the breech plug removed as some rusty junk makes it impossible to remove the breech plug by hand when you go to it the following season. I always clean my gun before storage too!---Dr Asus

Thanks for the input everyone there seems to be a general agreement here on the powder and sabot choice. I'm currently using the shockwave 250gr and 777 50gr.pellets and geting fair results so far but will consider all your input for a change.Thanks again.
