Has anyone tried 2400 in their 10MM? I see Alliant has data for it with 180gr bullets. I'm just curious, I have a lot of 2400 that I shoot in my 221 Fireball and 410, any comments would be appreciated

Haven't tried it. That powder is usually reserved for my 44's and 357's. It does not produce top velocity in the 10 (at least for their 155 gr loads) but would be good enough.
Looks like it does better with the higher end weights in the 10, like the 180, and gets close to many of the top velocities
If one was to stock up on powder and you could use 2400 in a few more cartridges, so much the better.
If you try some, be sure to post your results.

Peashooter, to 10mmTalk!

The reason I didn't try 2400, was because Blue Dot was shown to provide more velocity using less powder. This was confirmed in actual test from my pistols using Blue Dot matching & even exceeding the data from other sources. The accuracy I achieved using Blue Dot in the S&W 1006 and 1076 led me to keep using it.

Since I got the Glock 29, I have started working with Power Pistol which has provided a little bit better performance than the Blue Dot in the short barrel pistol.

Please post your data if you do some testing with the 2400, we can all learn something.

Definitely let us know. I am excited to hear about what kind of velocities you are getting.

Unfortunately, Alliant doesn't provide the psi rating for its 10mm loads (at least on the website). This would make it much easier to experiment.

The 180 grain load calls for 12.8 grains, with a velocity of 1214 fps. There are published data for two or three powders that will exceed this velocity by at least 100 fps. Thus, you may have to try using magnum primers with a slightly larger charge weight. 2400 is slower than any other powder for which there are currently published data in the 10mm. So you are quite likely to run out of space before pressures get out of hand.

Old Alliant load data states 12.9gr of 2400 runs at 36,000psi.

OK, I loaded up a few rounds with 180gr Zero JHP and 2400, here is what I came up with.
11.9gr 1149 1107 1097fps

12.2gr 1155 1109 1129fps

12.5gr 1185 1193 1185fps

12.8gr 1201 1226 1212fps

Recoil for my start load of 11.9 seemed a little heavy for a load this slow. After I fired this group I fired 3 rounds loaded with 13.5gr of #9 for comparison. The #9 load chronyed at 1210 avg and seemed to have equal or less recoil than the 11.9gr of 2400. At 12.8gr of 2400 recoil was noticably more than my #9 load.

I tested all these rounds shooting off a bench at 25 yards. Accuracy was about average for my EAA, not bad and not great either.

It was fun, but I found no reason to continue testing 2400 in my EAA.

Hey thanks for the post! Yes you have gotten the same results as published with the 2400 as others.

Blue Dot to me seems to be better in that you use less by weight and cost and get more velocity. I like the balance of accuracy, clean burn, pressure and velocity I get from Blue Dot with a wide selection of bullets.

That being said Power Pistol is also getting me some great results across the wide bullet spectrum for 10mm & 40 S&W especially in the shorter barrels < 4" like the Glock 29.

Just remember there are limits to everthing, and we should take a step back from those limits. I aire on the side of safety first!

Best regards

Well just add my 2 cents 11.6 grs of 2400 gave me tight groups with a 180 Gr FMJ from my EEA Wittness vel was around 1088 fps,and that was 10% from rthe max load of 12.9 in the Alliant Manual. Got to try this load from my Glock 20

I tried it a while ago, and it just did not perform as i would have liked. Not enought velocity for powder weight. I have read of guys using magnum primers and doing well with the 200 grain bullets, thouhg. Its not that useful for the lighter bullets.

Give it a whirl, your gun may like it.
