Circumstances finally allowed me to shoot the 1920 Remington Model 11 that I bought last month and posted about. It was right at dark so I was only able to run 15 rounds of Federal birdshot through it. All 3 magazines-full cycled perfectly and then it was too dark out to shoot any more. I know that's a short test, but I'm pleased it fed all this bulk pack birdshot without issue. Should do well with buckshot if I set the friction rings correctly. Not bad for a 92 year old gun.
