Tenon threads?

I must have been drunk when I posted this. Anyway, does anyone know the thread pitch of the 527's? Metric or English?

I own two of them but I've never had the barrels off - they both shoot about into one hole.

That said, I hope you get an answer bucause I'd like to know just in case ....

They are actually a metric but, I've rebarreled about a dozen of them, for a local sub-caliber shooter, and used .983x20. They all fit up fine.

Thanks Eddie. Would that be Ray? or some other small cal nut???

They were for Ray. I do them with a shoulder against the front of the action, as Ray gets barrels larger then factory. I have a trueing mandrel, if you wish to borrow it.
