Have any one fire formed a 303 bras casing in a 410 to reload it. I see that it is possible but I would love to have the reloading data if I want to do this. They say that you bring the cost of ammo down by a lot. There are a few YouTube videos on how to do this but no reloading data. If there is anyone out there that done this pleases give some advice.

Well since 303 ammo is even more expensive than 410 ammo..... why not just reload 410?

Some years ago, I owned a Saiga .410 bore shotgun (which was a semi-auto, based on the AK-47). I since sold it, but kept a bunch of the ammo for it. I later determined the slugs were incompatible with my tightly bored Mdl 24, but the buck shot was OK (there's a long treatise on this site somewhere where I felt it necessary to share my new knowledge  ). The Saiga ammo is in all-metal cases 2.75" long, but alas, Berdan-primed. I've kept all the fired brass, thinking that someday if I'm really bored or desperate, I could try converting them to Boxer primers and try reloading. The .303 case, as I'm sure you know, is 2.22" long, base diameter .46" and the rim is .54". My Russian brass has a base diameter of .447" and a rim of .530". I pulled some random Federal and Winchester shells, and their base diameter ranged from .45" to .46", rims varied from .528" to .530. So I guess....if the wider .303 rim will fit (maybe you'd have to turn it down some?), you could reload. Is it cheaper? I dunno. Even in these slim pickin's days, my stores have almost always had some .410 ammo available, although most of it 2 1/2". But since the .303 Brit case at 2.22", you'd be restricted to 2 1/2" loads. That's my answer about loads, BTW.....use 2 1/2" loads, with skinny wads so you can actually get the necessary shot and powder into the shorter .303 case. Unless you're living in a former British colony, you won't have access to much used .303 brass. If you can find it new, it's about 50 cents each. If you've saved your empty 3" shotshells, you can reload them at least 4 or 5 times. At least that was my experience. I had more time than sense once, and used a Lee hand loader for a time. It worked....kind of.....but it was r e a l l y s l o w . . . .  Edit: I just looked at your first post....you are in a former British colony! It might just be feasible! Certainly here in the US, it wouldn't be cost-effective. |

standard .410 data in say an RCBS data manual should do the job, case difference and powder charge should not change much in my opinion, but I haven't loaded in a long while.
