Anybody using 2400 in 300 blk?

[asmith80]

I know H110 and 4227 seem to be the defaults for 300 blackout, but I've got 8lbs. of 2400 that I use for the rest of my cast rifle loads and was wondering if anybody has experimented with it in 300 blk?

whoops, wrong section. Mods could you move to the correct place?

I've tested a few with 2400.
It cycles fine, has reasonable velocity averages, basically the only thing I did not like was the slightly lower velocities it produced.
In a 16" barrel 135gr jacketed stuff was averaging 1866fps and 150gr jacketed stuff was averaging 1657fps.
It also did fine with 220gr jacketed but I don't remember the data or velocity averages.

Like most powders, your mileage may vary. It is a good powder for the 300BO, but may not meet your needs. You need to give it a try and see how it works for you.
