Gun uses 2 3/4” shells. When I first got it, I was told I could use regular factory shells. Couple of rounds of skeet and the timing got knocked out of whack. Back to the gunsmith and it was returned, all set to go. I was told to not use ‘romper-stomper’ loads’ and did not know enough at the time to ask for more detailed specifics. More research has led me to believe that erring on the side of caution would be to use lower pressure guns. I have multiple other 20 gauges to use modern loads with. This gun is less a target busting, game killing ‘tool’ and more of a shoot occasionally for the nostalgia type gun. I’m trying to get ammo to hunt this fall with it. Anybody reload? I’d not argue about price in the least.

I am currently traveling and will examine the proof marks more closely when I get home. Current in Omaha, NE for the next 10 days, followed by northern Michigan (Traverse City area) for a month.
