Slow powder/excellent choice for a overbore caliber
4831 is my prefered powder for 270, high loading density (well above 80%), highest velocity of the powders listed for both the 130 & 150gr projectiles with excellent accuracy. I consider this number the best option available for 270 caliber, 4831 works well in a 280Rem, 25/06, 243, etc! William
