Therein lies the mystery between the bolt face and the muzzle. What works in one rifle will be different in another. I'm a Hodgdon guy for sure. I just tried Alliant powders because it was listed as the most accurate powder for a 270 win project. I tried it and it worked. Now I give both Hodgdon and Alliant an equal test when working up other loads. RE23 worked best in my new 280AI rifle project. Hoping the OP finds goodness out of all this info.I didnt have a problem with accuracy either with r26. It was just better with H4831SC.
