My 416 Rem was a fluke purchase for me. I was in Scheels one day and they had it laying on the counter. I talked to the sales guy and he said another customer had ordered a 416 Rigby. When it came in it was a 416 Remington instead. I bought it for about half price as they figured they would never sell it. Mine was a Ruger No. l. Since I have to shoot left handed because of the loss of my good eye, I could load the No.l as fast as I could work a lefty bolt because I am not left handed. Now the left shoulder is shot and still no right eye so things are getting tougher. They want to put in a new shoulder joint this winter as they say there is no hope for the old joint. Its totally shot. All the stuff that is supposed to be between the bones on the joint is just gone. I asked a carpenter friend of mine if he wanted to put in a bid on the job. All he would need is a steel ball, a plastic socket, some glue and one long screw to fasten the ball to the long arm bone.. Anyway I liked the 416 and it would be as good as it gets for grizzlys and other big critters. I loaded the Barnes X spitzers as well as the Hornady round nose. The Barnes were 400 grain as were they Hornadys. I think I still have two boxes of the Barnes bullets left over. I don't think they would be effective in the 45-70 but I don't know for sure what the recommeded velocity level for them is.
