I have the 25WSSM, and it is proving to be a very good shooter with factory ammo. Santa Claus will be bringing me some reloading dies for it, if I've been a good enough boy. Mine is the A-Bolt Stalker. I thought I would try one out, and if I liked it I would eventually get a 25wssm upper for my AR15, or a 243wssm upper....Ammo availability means nothing to me, as long as I can keep getting the brass.
