Very cool josh . To very nice old guns. Both worth some money these days. Old 410 looks like old 3030 bolt my dad had. My wife uncle use collection had quite few them before he passed in 12ga in 20ga no 410s or 16ga .
Check those hulls and see if the action is scoring them. Have the same shotgun and haven't used it for decades for that reason. I'd just look to make sure it's not a problem. 1 shell emptied all the powder into the action. Hard No.
Is the .410 something you are planning on selling? I have the same 1 but unable to find a replacement magazine. I broke mine years ago so it's a single shot lol.
