This year I was lucky enough to hunt with a buddy who drew a TMA tag. He shot his ram at 378 yds across a draw, for the same position he could have taken another 2 legal but smaller rams at 250yds.
For practice i like to walk around in the hills with some weight in my pack, get my heart rate up, and then shoot targets, rocks, whatever using my pack as a rest
Laying on sharp rocks using your pack for a rest at a steep angle with a heart rate of 120, is ten times the practice shooting from the bench is.
