Re: safe range for deer and elk w/ 7mm rem mag.
Of course an answer to a question like this depends almost entirely on the situation (Wind, rest, shot angle etc etc)
I've hunted with a 7mmRM since 1978, I've taken on the order of 3 dozen Muley's with mine from 8 yards to 870yards. A few over 500 yards and a bunch over 300.
Today, I'd trust mine to 700 yards, it is lethal beyond that but I've not shot it nearly enough over the last few years to go any farther than that. In good conditions, 500yards on a standing broadside Muley is a chip shot for a good 7mm.
This is certainly a decision that is different for every person. If you want some quantitative reasoning, I think 1800fps impact speed is a reasonable limit for deer. In the load I shoot, that is around 875yards.
Hope that helps.
If some is good and more is better, then too much is just right.
