I’m working with 143 grain eld-x with cci 200 primers. I’m hoping somewhat used superformance powder in the last year or so that could tell me how the combo is doing for them. I’m working with a 22 inch barrel and trying to increase velocity over factory 143’s
 
I got a decent boost over factory Precision Hunter using Superformance, about 100fps.

Accuracy was fantastic in both my 6.5s, My Fieldcraft loved it and shot under an inch at 2650fps in the 18" barrel. My 24" MPR would run 2800 with similar accuracy.
 
I found a unicorn load at 2900 FPS with 46.9 grains of Superformance and the new 140 grain Sierra Gamechanger. Turned my 24" barrel Tikka T3x 6.5 Creedmoor into a PRC light. No signs of over pressure.
