2400 for .308

[rustybayonet]

Wondering if anyone has tried using 2400 powder in a .308 round? I'm shooting it in a FN K98 bolt. I have found data on the round. 20 - 25 gr under a 150 cast. Can I keep the powder the same under an fmj?

I would start with the "UNIVERSAL LOAD" which is 16.0 grs. of Alliant 2400 it's a tried and true tested load in many 30 cal. military cartridges that just works. I shoot this load in my 300 Sav. & 7.62 x 54r and you can cover 5 shot with a nickel at 50 yds. all day long with my 150 to 170 gr. gas check cast bullets sized to .311" for the Sav. and .314" for the Mosin. A good read http://castboolits.gunloads.com/showthread.php?13425-Cast-Bullet-Loads-for-Military-Rifles-Article

Although the Lyman cast bullet manual list a max charge weight of 24 grs. of 2400 with 150 gr. gas check cast bullets I doubt that you will be happy with the results. A velocity range of 1600 to 1800 fps. with long heavy bullet generally give best results. Be very careful with what load data you use as you can go overpressure with 2400 very easy if you go over known published data.

With a FMJ bullet you also going to generate more pressure with an equal charge weight due to the added resistance of the jacketed bullet vs. the softer lead bullet. For J bullets in military cartridges I would recommend "The Load" http://members.shaw.ca/cronhelm/TheLoad.html

for reduced loads you are going to be fine. If you can find a load in a factory book it SHOULD be safe. I don't think that load will cycle a gas gun. Just don't try to get rifle velocity with 2400.
