Just had this Ross Schuler break installed on my buddies 7-08. It was killing his wrist and now it's like shooting a light load 223.Check out the video of the 7-08 after the break- NICE!
Eric Wallace is the only one I could find that will install on an Encore barrel ata reasonable cost and time frame.

I got this 338JDJ barrel with the Magna Break instlled on it and it really tamed it. It was tuff to shoot with 180grn bullets and a full load of Varget with out the break. You could take off the break and install a muzzle thread cap.

You don't quit playing because you get old, You get old because you quit playing.
