I've always used a charge of 58.5 grains of Re 15 under the Hornady 250 grain Spire Point. Never noticed a problem, until I stared using a new 5 lb keg. Compared the new loads with a few of the old lot of Re15 and saw definite pressure indications with new stuff. Ejector marks were obvious on cases loaded with the new powder, but nothing on the old. I'll be backing off a grain or grain or two if I buy another box or two of the Horns.
Right now I'm loading the 250 grain Nosler Partition on top of 55 grains of Re 15. I know it is 2 grains over the book max, but the velocity is below the book (about 2460) and I see no sign of pressure either on the cases or by recoil level as compared to the Horn load. I'll probably use this load for elk in couple of weeks.
