Hey bjp
in my barrel the 90 xtp was poa/poi @ 50m with your brew of 4.50 grain AS50N powder [ scope set to zero @ 75m with the Hornady 190grain sub-x]
Very pleased with that outcome Mate .have loaded some of the same projectile with 5.00 grain AS50N just to see what happens at the longer range
Cheers to all
