[QUOTE="Guest, post: 12095"] Jaeger476: First off, I use both the IMR 4831 and the Hodgdon 4831SC in my .300 win mag. The IMR is a hotter, snappier, and quicker burner, by about 5%. The Hodgdon is smoother burning and takes three – five grains more powder to achieve the same velocity as the IMR. I am utilizing the IMR because I have so much of it, however I prefer the Hodgdon. My loads for my .300 win mag utilizing Remington Cases is 66.8 grains of IMR 4831 and the Fed 215m primers and Berger VLD 210’s. If I were to charge Winchester cases it would be 67.8 grains, because different manufactured cases in general create different pressures. I have found Winchester brass to produce the slowest results (probably the least desired brass), where Remington cases produce faster results and Federal cases even faster. This is because of the thickness of the casing wall, the different parts of the cases that have different hardness (neck and head) and it’s overall tempering/annealing. Remington Brass is alright but Norma or Lapua is best. [/QUOTE]
