    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

    Bingo!

    If recoil is equal the bullet that spends longest in the barrel will hit higher on the target since that gives the recoil impulse longer to lift the muzzle before the bullet exits the barrel.

    So if you're comparing loads that recoil about the same amount the heavier bullet will be going slower, will spend more time in the barrel and will hit higher on the target at typical pistol ranges.

    If one of the loads recoils MARKEDLY more than the other load it will probably print higher on the target. The much harder recoiling load bumps the muzzle upward much harder as the gun recoils and will result in the muzzle being higher when the bullet exits.
    "

    This suggests a lower velocity load than produced by 13.5 gr of 2400 stated by wallnutt. For same boolit weight, this usually makes sense...unless there is an extreme difference in powder charge weight which contributes substantially to greater recoil.

    Some interested threads have come up over the past year or so about people experimenting with this powder in metallic cartridges...most of those threads never really concluded.

    Any of you prior experimenters care to share? Marlinjunky, Lar45? I know you guys considered it, but your last reports to me were that it fell by the wayside to other powders
    This!

    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 Iím 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 didnít experience anything near spikey pressures I did experience inconstant ignition. I did not set up my chronograph so I canít tell you velocities but by presceved recoil some went pop and some went bang. I donít think a small pistol primer is hot enough to ensure consistent ignition. Perhaps a mag primer? I donít really care enough to find out as I have pounds of 2400 and H110 I donít see the necessity of chasing it further. I see why Alliant probably doesnít 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
