6lbs, 4ozs, might be a bit too light for a 10 gauge. My Nitro 16 weighs about that, but, I don’t shoot anything heavier than an ounce of shot out of it.

For some reason, a 12 gauge Ugartechea I own, that weighs the same 6lbs, 4ozs, seems to wallop me when I run 1 1/8th ounce factory loads in it. It has 3” chambers, but, I would never try that. 1 ounce Vintagers make it far more friendly to actually use.

Best,
Ted
