I have a 12" encore barrel coming but have no data on this Caliber for the Speer Gold Dots and the heavy cast LBTs.
Any info will help.

Thanks

You can start here perhaps:

Good luck. I'd love a 480, but I am gonna wait until Ruger decides a special run of 5-shot Bisleys would be a good idea.

Thanks guys.
