I'm in the early stages of having a rifle built in 7MM Rem Mag for elk hunting. I have the option of having the rifle built with a 24" or a 26" barrel and I'm not sure what would be best. What would folks here recommend? I primarily do my elk hunting in Montana where 300 yd. shots are more the rule than the exception. I appreciate any recommendations.

Thanks,
