I am currently using a choate tac. Stock on my 300rum. It is a 30" tube that is 1" at the muzzle. The stock will be replaced as funds come available. It's a very sloppy fit at the action. At the tang the tang sets up off the stock. When righting down the action screws it try's to cant and does not run straight with the stock. At the forehand it looks like the aluminum bedding is coming through the overlay. Maybe I got a bad one. I do realize that it's a lot of weight. Right around 20 pounds. Looking for its replacement now.
