Age old question about RFI .410

[aspen80]

Sunray, I want to know in the conversion if a modern 2 1/2 " 410 shell will chamber, but a 3" won't.

if a modern 2 1/2 " 410 shell will chamber, but a 3" won't.

The original chamber was based on a blown open .303 cartridge and had little to do with an actual .410 shotshell. Then many were re-done with a .410 chamber ream to the shorter. The 3" mag would be one more step I think. You'll be able to slip it in to a point...
Does that help?

I got it Jim. Mine has been reamed out to accommodate a 3" shell.
So, the hunt is on again. This gun is immaculate and has cartouches and all, just been modified.
Thanks for the info.
