Slug gun project

[Slugun45]

Anybody on here shooting a closed ignition with primers? I would love to hear from you?

Here in Friendship, everyone uses a sealed ignition with small pistol primers. Back in the mid 80's everyone switched from percussion caps to primers. Are you planning to make the sealed igniter with an interrupted tread? Harder to make make , but a lot handier than screwing it in and out each time.

Yes that is what I am going to make. My concern is it will be on an underhammer. It seems that the primer needs to be sitting in the cap,next to the firing pin to close the ignition . Hope this makes sense. Other words if the primer was put on the end in the barrel what would keep it from falling out while trying to attach the other part? I would love to see a picture of one.
Are primers allowed on all bench and slug guns at Friendship?

primers are only allowed on slug guns. I'll try to post a picture of the sealed ignition later today.
