I have many discusions with D Lazer, master Alaskan guide. He has been involved in over 300 brown/grizzly kills. The most jams have come from M70 winchesers and mausers. Remingtons and the tang safety Ruger M77's have been the most reliable. His back up rifle is a tang safety M77 30-06 loaded with 220 gr factory.
