I have a new center feed Savage 11BTH in a 204. It feeds 39 grain Sierra Blitzkings just fine but it will not feed Varmint Grenades or 40 grain Bergers at all. It hits the edge of the barrel just low and to the right of the opening of the chamber. Do others have this problem and what can be done to correct it? It is frustrating when trying to try something new, work up some loads and have to hand feed each round. Takes all the fun out of it. ??? Any help would be greatly appreciated.
