What’s acceptable headspace in a revolver?

I loaded a bunch off 7.62x38 brass cut down and sized for a 7.5swede nagant. My question is the headspace. There’s a tiny gap between the case head and the breech where the pin strikes. It’s less gap then my credit card. Should I worry about this? I’m loading with bp and bp substitutes. I don’t own a gauge so I used a credit card and it’s less gap then the thickness of the card. Would this be considered safe enough to shoot?

I can however just insert a folded double regular weight business card. It’s snug.

Don't worry about it.

I won’t! ... it just crossed my mind to check how much play to the rear the cylinder has, I can pull it back a touch in the fired position and it closes the gap.. an oversight of mine that I should have checked in the first place.

mine all rattle around a bit, it's normal. Did you shoot your BP loads yet?

Not yet, was waiting for the thaw and now waiting for the range road to dry out, so we can drive back it without getting stuck lol!
