I've used 20/28 in place of Unique by weight and it works great but I can't find 20/28 now either.

I have found several containers of 410, and a couple of times that is all that was available.... So I Am happy to have a few lbs of it....

I think the secret on 20/28 is out. Oh well...

I have not noticed any 410, but I know some folks have had luck with steel in 44 mag, so when it became available, I picked up several pounds just in case I NEVER see 2400 again. lol
Back when powder was hard to come by I bought 2 pounds of 410 because I heard it was close to 2400 and I also load 410. Last night I swaged up some 38 caliber 158gr and thought what the heck I have 2 pounds of this stuff may as well see what it does. Note that it has been said here that this powder is almost the same as 2400 but gets spikey in extreme cold. Here in southern Missouri it never gets extremely cold and if it does I’m staying in the house. So I loaded up 12 357mag using 12gr of 410 a Tula spp and my 158go home swaged JHP. My results were what I believe Alliant was worried about. While I didn’t experience anything near spikey pressures I did experience inconstant ignition. I did not set up my chronograph so I can’t tell you velocities but by presceved recoil some went pop and some went bang. I don’t think a small pistol primer is hot enough to ensure consistent ignition. Perhaps a mag primer? I don’t really care enough to find out as I have pounds of 2400 and H110 I don’t see the necessity of chasing it further. I see why Alliant probably doesn’t publish anything but 410 shotgun loads for it
is this powder close to accurate 4100? I found loads for it in the 44 mag on accurates load data
