[QUOTE="rettrpjch, post: 503430, member: 32981"] Been shooting 300RUM since '99, first year of the ultra. Killed dozens of big game. Used IMR, RL, and Hodgdon powders. Tried sierra, barnes, hornady,and nosler. Up until this year my combo for speed, accuracy and energy was Imr-4350 and 180 nosler partition-a deadly combination. But my newest, best and favorite load is as follows: Remington brass trimmed to 2.840,180gr.Nosler Accubond bullet seated at 3.668",just enough to fit in the mag., CCI-250 primer(primers are less important than the rest as long as you get a good seal) and 98gr. Retumbo powder. Most sites recommend starting a certain percentage less than max and working up. I start at max, watch for pressure signs, and work down. Maybe not the best way of doing things but get the absolute most out of a round. This load was decided upon after MANY rounds of trial and error, using a variety of all of the above. As you have probably read, all guns like a certain amount of this or that. Just saying that this may work for you. Chrono showed average of 3450fps at 10 ft. Energy is 4750 ft.lbs. I enjoy long range-so this combo is still packs a whallop, even at 500 yds. the bullet only drops 26" with +2" at 100yds. And the energy is still 2475 ft.lbs.
