[QUOTE="Diamondback, post: 803256, member: 29413"] [URL="http://www.longrangehunting.com/forums/members/magnummaniac-10755/"]MagnumManiac[/URL] hit the nail on the head. Every once in a while a rifle will like a fast burning powder pressure wave with less case fill. I experienced this with a 270 Win shooting 150gr SPBT's. It liked Varget over H4831, H4350, or Hybrid 100. Every rifle is different on what powder it likes for what bullet you are using. The Varget also gave a much faster softer recoil and I could tell the difference. I do the powder ladder with a specific bullet I pick for what it designed to do / game I will be hunting, then the seating depths starting with SAAMI OAL till I capture the special powder for the bullet off groups and then move on to seating depth based off the Rifle's mag length capacity past SAAMI spec. SAAMI bullet depth to find the most smallest groups off the powder ladder. Dial them in, and then play with the seating. Usually 0.010 off the lands works on the majority of 700's I have shot. Each rifle is different on what it likes and pressure increased closer to the lands or slower back off them. That can change my powder loads to back off a little to tweak the combination where they meet for the best accuracy fps recipe for that round / barrel harmonics / pressure / timing. If I get 0.75-0.50 MOA in a SAAMI spec length powder group load, I'm happy- Factory T3 Tikka's come to mind.
