Which model bat?
Do you use the panda with or without the recoil lug? Also do you bolt them in or just glue them? If you glue them what glue do you use and what bedding compound?I have used trued Remingtons, Bats, and Panda's. I favor Panda's because they are the only action that holds universal dimensions of the barrel threads enabling any smith to supply a barrel without the action in hand (with the exception of very early manufactured units). They got the fire control system right the first time. I also like the aluminum construction as I feel it provides better vibration dampening......and the people there are #1 in customer satisfaction.
I would use a dual port melonited Bat B action. Most folks end up jamming the 30 br bullets hard in the lands and I think this ends up being a little hard on the lugs. This is why I would use a melonited Bat action.
