Home Forums Reloading Big Game Rifles 162 ELD M in 280ai

For those that run this bullet, what powder are you finding to work the best? Mine will be a 1:9 @25".

A little different, but I am using IMR 7828 in my .280 Rem with 160 gr. Sierra Game kings. I don’t know why that same powder wouldn’t work in the .280 AI.

Ramshot Magnum, RL-26, H4831sc, IMR 7828ssc

I use H4831sc with 168 bergers.

6.5 Staball was good for velocity.

Anyone have experience with IMR or H4350 powders?

Charge weight, velocity, with the 162?

IMR 7828. R23

With the 162gn ELDX and a 1:875" twist in 22" tube;
Fed 210M primer for all loads.

60.5gn IMR 4831 for 2916fps
61gn Rel 22 for 2845fps
63gn IMR 7977 for 2821fps

These loads shot between .311" and .646"

I used H4350 with the 160gn Accubond with 57gn for 2821fps but tended to use slower powders when I got to these heavier weights. Rel 17 for example and 57gn generated 2920fps with that same 160gn Accubond so that general 4350 burning rate looks like it has a lot to offer with the 160's.

IMR 4831 was a very good powder with 160gn pushing the accubond to 2948fps and under .5MOA.

I've shot a fair amount of the 162 eldx, which should be similar.

Best of bread summary, all sub MOA, 24":
~60.5 gn of IMR7828 @ 2,960fps
~58.5 gn of RL23 @ 2,890fps
~60.0 gn of RL22 @ 2,950fps
~57.5 gn of Hunter @ 2,880fps
~65.0 gn of Magnum @ 2,950fps

RL-23 is probably my favorite; works very well with 140-175 pills. I also shoot a decent amount of 7828 w/ 160 and 175, as the accuracy and velocity are very good!

Work up; I don't have pressure testing equipment, and cannot validate these are safe.
