    i have a pound of 4831sc and was going to reload some 280 for my brother. Gonna use 150 gr ELDX in once fired brass. Question is I have found load info for h4831 but not h4831sc ? Use same grain and what about primer? Regular 210 or 215? Anyone have good mixture to start with? This will be a whitetail rifle for 0-500 yds. Thanks

    H4831 and H4831sc , is the same powder , use the same load info . the "sc" stands for short cut . "sc" will be shorter kernels of powder .

    H4831sc packs denser than H4831, so compressed charges might be a little lower for max on H4831.

    I am running 59 gr of H4831sc behind 140 gr Nosler Accubonds out of two .280s. Both Browning X-bolts. Sub 1/2" groups in both at 3040 fps. This is over BOOK max but the book loads were for the Remmy semi auto and pumps (742, 762) back in the day, which had to be anemic due to weak actions. You can load to 270 pressures according to most .280 loaders.
    Btw: I just came off a 10 day hunt in WY and took five antelope with this load. All five dropped in their footprints.

    I only shoot the162 Amax in my 26" custom 280. H-4831 was a bit too fast burn rate, so I tried IMR-7828 with the heavier bullets. With bare bullets, accuracy load was 56.9/57.0 at 2,800 fps. With HBN coating, the 162 was hitting 2,875 fps over 57.8/58.0 grs.
    Accuracy is in .1-.2" to 200 yds. In good conditions, it will group 3 shots under 1" @ 400. To my way of thinking, the 162 Amax is the ideal bullet for antelope and deer in the straight 280. My only game with this rifle was a goat @ 605 yds and both lungs were destroyed, never took a step. IMG_20181031_213032206.jpg
