I bought a couple of boxes of Speer Mag Tip 350 gr bullets for my 416 Remington..mainly for sighting-in and practice. How do these bullets work for moose and bear? I also have 350 gr Barnes TXS for more serious hunting. I plan to load them at about 2400-2450 fps using RL15. This is my new toy I had built over the winter. What do you think??
