Just been loading for this caliber for a short time.
Currently have tried the Nosler 250gr partition over 83 and 85 grains of IMR 7828. With my rifle the 83gr I'm pushing 285X -2900FPS and the 85gr 301X 3050FPS. The load data I work from states, "the high load in the data for this powder was 89gr", I HAVE NOT TRIED that. SIDE NOTE: max is around 105gr for the 338LM for powder it can hold, MAX Capacity. It also stated that the 83gr load shot most accurate. I have been happy with the 83gr load thus far, much more to try.
I have some lapua Scenar 250 bullets to try next on the list, haven't picked the powders yet.
Custom Loading Information... Be Careful, start with a low(er) powder load and work up.
