I do have a question on what size the barrel threads are on your action if it is the early small thread action have the threads opened up inside the action to as large as safly possible if it could go to 1.062" the same as a remington it would be much better for accuracy and safety. I hope this helped Cheers Bill Australia I am in the process of building a rifle for a coustomer to shoot them at that velocity it is also to be a switch barrel rifle. [/QUOTE]
