GRI Ishapore 410 Questions

not sure if it was reamed

That wouldn't matter, like I say, I can make ammo.

Some people are real picky for that, depends on the collector I guess.

I generally do my absolute best to keep things as original or like original as possible with repro parts as needed but this one just isn't a big deal to me for some reason. Maybe I'm just starting to get tired of having to hunt down obscure ammo all the time. I did see the 410 brass cartridges at the last gun show. Three different vendors had it and were selling it in bulk boxes and it wasn't priced badly. Curious to whether the original ammo can still be used if it was reamed out for modern 410. I'm sure it would fit but what would happen as it passed the extended lip?

Not so much that, just that I have everything here to do it. If it's reamed for standard .410 then I'd use that.

If it's reamed for standard .410 then I'd use that.

Is there an easy way to tell if it's been reamed for standard .410 2 1/2" shells? My 1948 RFI chambers a standard shell just fine, but I've never shot it. If it chambers okay, does that mean it has been reamed?

I'd say so...the originals weren't really .410. That's why 444 Marlin fits well. If you look at the original cases, you can see better.

Springfield Sporters reamed a ton of them for 3" standard .410 shotshells back when they were $79.95 each.

[browningautorifle]

Probably more than just a ton...probably a couple of metric boxcars full...
