Looking for opinions on what rifle to use on a mule deer hunt I have scheduled for this October. I typically carry a Rem Model 70 Mountain rifle in 30-06, nice light weight rifle but not the best shooter. This years hunt will be a little different, it's a very sought after limited draw tag and I want to make sure my rifle is up to the task. I have a 257 Weatherby, a 7MM Rem Mag and a 300 Weatherby Mag plus the 30-06 to choose from. I'm not a hand loader so I'll be experimenting with different loads for the rifle I choose. Any and all opinions and thoughts are appreciated.
