Is anyone loading 303 cases for 410 shotgun? Seen a little info on it and I would like to try it,so method, load, primer to be used and what is the advantage to do so , besides just to try it , my bud has a 45-70 lever, shoots 2.5 in 410, but has a problem eject the hulls, so I think load some 45-70 cases with a shot load?Any info would be great.

Use the 444 marlin. They are a perfect fit. I checked .303 and they are a loose fit.

Your only problem and that is what I am currently trying to figure out, it how to reload.

I think you need a set of 444 marlin die and then a roll crimper to crimp the brass. Unless it is for single shots and then you just need to glue the over shot card in with a hot melt glue gun. I do that for my magtech 12 gauge.

Don't fudd up your 45/70. There are postings here and on the net that are not in favour of using shot out of the 45/70. I think it messes up the rifling and you get a hole in the center of the pattern
 
I use 444 brass with no problem.

But I shoot mainly slugs and cast bullets with my .410. I shoot .380 wadcutters, .40 caliber semi-wads, .395 lead balls, plus buckshot.

Buy a lee universal decapper for $12 to deprime ANY brass you have. Use large pistol primers, an oversize overpowder wad and an oversize fiber filler wad(.430), then use an oversize(.450) overhot wad over your shot. You can buy oversize wads cheap from 'Track of the Wolf' in the States.

When I use slugs I just put a drop of Elmers glue on the top wad and drop my projectile on top, then spin them around to spread the glue. They usually stay stuck.

I use 15grs. of 4227 and have had good results IF you get a good seal in your .444 cartridge with your oversize wads. I find I get a good seal if I stagger overpowder wads and fiber wads.

I've put a .40 caliber cast bullet through 6 inches of firewood with this load. It might go sideways, but it still goes through. The most accurate loads are the .395 round balls, but shooting big cast bullets out of a .410 is like having a mini-45-70.

In case your wondering, I'm shooting all of these loads out of a 70 year old, full choke, single shot, 'Bay State' H&R shotgun.

My friends love shooting it too. It's light, doesn't kick much, and is fun.

Don't see how it would mess up your rifling at all. It is true though that you do get a hole in the middle of the pattern - this makes sense as the shot comes out, via the rifling, in a spiraling circular pattern.
