2400 test in 308

Have been meaning to do a test of 2400 with cast for a long time, and finally got around to doing same yesterday, at 50 yds with NOE Hunter bullets, BR/Bll, Al GC, .310, bullets not weighed and separated, close visual however. Starting with 17.5 gr. and working up a half grain at a time. Loaded ten of each, shot 5ea at 50, will shoot 5 ea at 100 next time out.

17.5 gr-1.7",/ 18 gr 1.85",/ 18.5gr-1.4",/ 19gr- .1.525",/ 19.5gr.-.94",/ 20gr-1.4"

16gr of 2400, 5 shot groups in this rifle will stay under an inch with weighed bullets pretty much all day at 50 yds, with some approaching one fairly large hole. Somebody on this forum recommended 17gr. which is why I used that as a starting point. With the weather getting better, and less mud to contend with, will be hopefully hitting the range at least once a week for the next few months.

The 19.5gr loaf shot really well. I would say you are starting to get some pretty good velocity at the charge too.

After I do a comparison of loads at 100 will do a comparison of groups
at 50 and 100, and then settle on (I hope) the most accurate 2400 load
with this bullet (but with weighed and segregated bullets). Think that
word is still in the dictionary.

I haven't done a lot with 2400 but it's an "easy" powder most of the time. Just tweak seating depth, charge weight, or add Dacron until it starts burning consistently and you got it made.

Thanks Ian. After the 100 yd test, will start tweeking as you
recommend. I haven't added dacron to 2400 loads in a long
time now, but that will be one of the tweeks when the time
comes.

2400 is one of my favorite powders in 30 cal. rifles using cast bullets, the Ed Harris Universal Load is one I use in 300 Sav. and 7.62 x 54r on a regular basis for general purpose shooting. I get slightly better velocity using 150 & 160 gr. bullets in those rifles then Ed's listed velocity for 170 to 180 gr. bullets. I don't use a filler with any of my 2400 loads and I didn't weigh any of the bullets I use either.

a couple 5 shot groups, bullets gas checked and lubed with Lee Alox/JPW lube.

I've gone up as high as 19.0 grs. of 2400 in the 7.62 x 54r using the Lee 185 gr. RN bullets. Gas checked and lubed with LARS 2500+. I have a little room to go but for backyard shooting with low recoil these loads are fine.

2400 has also been a standard powder using 14.5 to 15.0 grs. with gas check 155 or 160 gr. bullets in my SKS rifles for many years. I always keep a good supply of 2400 around, I have a couple 357 Mags to feed as well.

if you position it in the case and the groups suddenly get real consistent, that's an indicator.
I really like the 19gr area in the 0-6 but I do keep the powder on top of the primer.
rifle and pistol primers will show enough difference that I know the load is on the edge, but it shoots well enough fr ground squirrels out to 100yds or so in the field.


edit.
I'm startin to like that guy above me.:)

That a smoker I see there Waco?

300 Savage is a good cartridge. With cast it does tend to favor bullets with not much bullet in the neck. As if the case has a neck.

Nice. Looks like it has seen some use too. May be doing a brisket this weekend.

That 300 Savage needs to get a good workout with cast.

Discussion of working with 2400 in medium rifle cartridges to bbq in three posts flat. Dang. Now I'm hungry and I want to shoot that 300 Savage of Walter's real bad.

You want to shoot his rifle or fire it?

And yes, the drift was fast. Unlike good BBQ.
