I find the single most important thing with encore barrels is to free float them. To do this I use 3/16 flat neopreme rubber washers. They work great for free floating the handgruard. Also check to see that there isn't any contact points touching the barrel from the handguard. I also glass bedded my reciever in my laminated wood stock. I am hoping that it helps strengthen the wood stock. I have had a few wood stocks split while loading a 209x50 encore. A good trigger job is alo important.
