i've been thinking about building a xp100 for some benchrest pistol shooting. I want to just go with a custom action instead of trying to hunt a used xp100 to blueprint. Who makes quality custom actions, and which one should i go with. Probably will be chambered in 6mm br. I also would like to have some advice on stocks. I need a good quality stock for a lefty. thanks for the help.

Take a look at what Eric Wallace does...
