I use the same action for light and heavy ( Bat ds ) your going to get many opinions on diff actions. If your thinking about getting a new action and just want a heads up before you make your choice this is a good forum to get good advice. I have a few friends that i got started in benchrest they also wanted to know what action was right for them , most of them thought they where going to buy bat actions. So i took them to the range and let them shoot a few of my actions ( Bat ) ( stolle ) ( nesika ) and a viper. The end results were after they tried each action some of them changed their minds and ended up buying a diff action than they thought they were going to buy , some liked the Bat action and some liked the viper some liked the nesika and stolle . One of them liked the viper with the drop port so much i ended up having to sell him mine, he couldn't find one anywhere else. Nothing feels nice like a custom action, you just have to go out and shoot one or two to see what you like
