I have a 30-06 w/boss and a 25-06 w/o boss. You can shoot anything except the Hornady Light Magnum or Federal High Energy type loads. The BOSS system is awesome, if you don't mind tinkering with it you can truly dial them in for tiny groups. Recoil is noticably less than a bolt gun. Reliabilty is a non issue, no problems with either one.
