410 bore

[RUGER]

I have a single shot Stevens 410 and the barrel stamp doesn't match anything I can find
What are the dimensions for a full and modified choke at the end of the barrel ?

I think practically all 410's are full choke. At least all the single shot cheaper gun. Since 410's are measured at only 25 yards instead of 40 yards for the amount of shot they put in a 30 inch circle to determine their choke, they almost have to be Full to be capable of killing anything. A 410 has less shot and spreads a lot faster than all the other gauges so Full choke is not really the same as Full on any other gauge.

Most don't realize this
