I have an older box of Rem 12 ga 1 oz #8 but is quite old. I've heard remington is out of business...?? Looks like RST is the way to go.
I'm in Frederick and went to school at the Mount so I'm quite close to you.
I really appreciate the offer. Is there a chance those chambers are longer? I assumed because of the date and model it was 2 9/16 for certain?
