Slugged my bore ?

[Oldhobo]

I picked up a 1 in 28 barrel.
I slugged the bore.
.499 x .506. What am I looking at for a bullet size, mold?

 

[45-70]

.499

May be a dumb question but wouldn't you want a .507ish mold to seal?

I'm assuming your measurements are of the slug. With a pure lead bullet I would go with .500-.501. If its too tight you can always size down.
