Snider loads

[Claven2]

I have shot plenty of smokeless in my Snider as have many others. True, you can't be as brainless as you can with blackpowder (where full cases are generally safe), but if you are competent to reload smokeless in 30/06 (where mistakes can be costly), you can reload smokless for the Snider.

I posted a ton of info over on http://p223.ezboard.com/fbritishmilitariaforumsfrm2

I find that either a very few grains of a moderately fast pistol powder like Unique, or about 30.0 grs of a slow pistol powder like H4227 worked well for me.

Did you use a filled for the hollow space left in the case, or are the powders you're advocating reasonably resistant to positional sensitivity to not matter much?

This could become a very long discussion (and maybe it should).

I worked up four loads that I have employed in 24 ga Fiocchi shotgun hulls (some with a shot wad acting as a sabot), and in the brass Magtech 24 ga shell. All loads were under a 480 gr custom cast bullet, and are quite mild, my objective being 1100-1200 fps. None used filler, except the shot wad which took up all empty space, and only the Unique load was seemingly unaffected by position. I found H4227 the slowest powder that would burn consistently at the low pressures I employed (~12,000 psi) - slower powders tended to just spit out the bullet along with mostly unburned powder.

Unique - 18.0 grs - 1150 fps
SR4759 - 35.0 grs - 1100 fps
AA5744 - 35.0 grs - 1100 fps
H4227 - 35.0 grs - 1100 fps

I intend to try some IMR Trail Boss (15.0 grs) this winter. Trail Boss is VERY "fluffy" - 15.0 grs would consume as much space as 30 grs of Unique and 40-45 grs of the others and might be the perfect powder. I'll report back.
