Anyone Tried Alliant 410 in Rifle or Pistol Loads Yet?

[35 Whelen]

Well, we're back at that point again where most powders are unobtainium. I've been using lots of AL 2400 in my M1 Carbines, but can't find it anywhere. A local gun shop was all but sold out of powder except for 4 ea. 1 lb. containers of AL 410. Since I've used 2400 to load .410 shotshell, I figured 410 must be close in burning rate to 2400 and snagged a can. I started load development using a minimum charge from 2400 data. Long story short, according to my chronograph results it burns a bit faster than 2400, but accuracy results have been wonderful. I tried it with one jacketed load but got wide velocities spreads and put that on the back shelf.

Anyone else tried this powder?

35W

I’ve got a can on the shelf from when I was loading 410 shells and every few months I google this similar question. I’ve yet to come up with anything compelling enough for me to try it yet.

I tried some in a 9mm carbine. Filled the case most of the way up with about 10gr, only got like 1,000 fps and a bunch of unburnt A410.
In small primer metallic cartridges A410 appears to want to burn slower than AA9.
So I'm thinking in something like 30 carbine, A410 would burn slower, more like H110 or 2400.
I have an M1 carbine and loading rounds with A410 does interest me.
But in accuracy contests with 30 carbine with 110gr bullets, H110 always wins.

I think AL410 would be way too slow for a small case such as a 9mm, hence the unburned powder.

Using identical components, I've found AL410 to be slightly faster burning than 2400, which of course is slightly faster burning than H110/W296. When loading a 118 gr. cast RN from an RCBS 30-115-SP mold, 13.0 grs. of 2400 and 12.0 grs of 410 give all but identical velocities (1900 fps). As far as accuracy is concerned, I've never given much credence to "accurate" powders, especially when loaded and fired from military arms such as an M1 Carbine. But 410 has been great for me so far. I shot this group this evening at 100 yds. with the aforementioned load of 12.0 grs. I blame the vertical stringing on the fact that it was cloudy and really too late to be shooting, but still not a bad group at just a smidge over 3".

Hey I found a "A410 in a 44mag" post on another forum and they're saying A410 loads a lot like 2400, but subtract at least 1gr. Supposedly burns cleaner than 2400 too.

3 MOA in 30 carbine is perfectly acceptable, especially if you're only burning up 12gr of powder and getting full 30 carbine power.

There is an alliant support guy on this forum. I had the same ideas with alliant steel and the guy all but squashed my plans. There were several guys working up 357 mag loads using it. I never got any as this was pre rona and I just bought 2400.

The reason why A410 burns so much differently in a small case vs as shotgun ahell may come down to the primer.
A small primer is typically loaded with 0.3 grains of stuff. A typical shotgun primer is loaded with more like 1.2 grains of stuff.
