I am using, the regular AccuBond's, the 140 grain at, 3,140 FPS, in my .270 WSM and they shoot real good (easily, sub MOA) BUT watch, the Bullets OAL from, Lot to Lot, as they VARY as much as .025 ( Mine were .020 short from first batch, to 2nd !) Not a big problem, just be just be aware and set your OAL accordingly ! I called Nosler and they actually varified that they could be off that, much ( .025) from each "set up" and Run ! If you find a good load, buy several boxes of, SAME Lot # ! The AccuBond bullet, has a Tangent Ogive design, so they shoot well, "Jumped" in long Freebore Rifles like the Tikka's ! The .270 AB's, are supposed to expand, down to 1,800 FPS that gets me out to about, 750 Yards, on Game, if needed. After doing a lot of research and now shooting them,.. I LIKE them !
