About 30 ears ago at the same time I started hunting and collecting doubles I would stop at tag sales here in NY while driving around for work. One day I found a high condition Stevens 5100 (precursor to the 311) in 16ga. w/28"bbls., 75% case color, 95% blue and wood.
Not long after, still being new to actual hunting, I read that CYL & CYL is perfect for woodcock. Out came the hacksaw, bobbed it bac to 24" and did a very nice job, patterned well. I filled in gap under the ribs with some Brownells solder.
Sure wish I had left it alone.
