I've got a Browning Hells Canyon Speed in 26 Nosler. Mainly my mounting hunting rig. Seems to shoot good with Factory Nosler trophy grade 140 grain Accubonds. Not so much with factory 142 grain accubonds. I am up in Canada. Getting harder to find factory ammo for the 26 so figured I better start reloading. Went with the Barnes LRX and US869. Found a few people on here that had good success with it. Results were sub par. 2" groups at best. Tried a number of powder weights. Did not change the bullet depth yet. I don't get a lot of time to work up loads so wondering what I should do next? Powder and bullets are sometimes hard to come by and far from cheep. so I am hoping to just change one thing. Powder or Bullet. Any suggestions?
