I hate too much thread drift.
I bear no malice toward RRL's. I've enjoyed shooting them.
And the looseness is by design. It's intentional.
For me, it's just that having come from the "Tighter is better, Tight is a sign of precision, and Loose is bad" school, I can't appreciate the RRL's genius.

The OP wants to be rid of an old hammergun in good condition.

I advocate putting an ad up here, and selling it to me or someone else that wants to participate in the Hammer gun shoots for short money.

Out there doing it best I can.
