I have a Stiller Predator repeater action barrelled in 7WSM, bedded to a McMmillan blind magazine stock. Based on Stiller's recommendation I purchased a Wyatt center feed magazine box with a flat follower and a standard Remington short action follower spring. My gunsmith can't get it to feed ... the first round feeds but not with 100% reliability and the second round will not feed at all. Have any of you had this problem with the Predator? What was you solution? Any help is greatly appreciated!
