The message I got from T/c almost 2 years ago, was they would not chamber the WSM for the Encore due to too much metal having to be removed from the barrel, causing it to be too weak, and a possibility of it blowing up. Well that burst my bubble, because at the time, that was my reasoning for getting an Encore to buy the barrels in 270WSM and 300 WSM! Well I have my Encore in 7mm-08, and love it. I've heard of a few people getting custom WSM barrels, and couple have blown up on the owners. I wouldn't chance it.
