Back when I elk hunted, I used a 7 mm Remington mag, and settled on 175 nosler partition bullets, 160 partitions were successful, too. Never killed one past 125 yards...most were around 35 to 75 yards in the pole thickets. You don't need accuracy, 2" at 100 yds is good enough...your target area is huge. I also load for higher velocities to keep exit holes big. A low power light weight Leupold duplex scope 3-9X....9X is huge, and never used.
Went to a 250 gr 338 for even larger exit holes, and a 2-7X, set on 2X, It's fast shooting, soon as the rifle hits your shoulder,.. fire...you wait an extra second for a good steady sight picture, your animal is gone. Animals are moving in the thickets, so you learn to kill em on the move, to a full out run. There ain't no long range braggin shots in the pole thickets, ya can't see 50 yards much of the time...I dress in camo, like a bow hunter, no orange, and hunted Desolation alone, no roads. Killed a bull every year when I was young, and could hike the mountains and canyons for miles...Got to be too much work packin meat and antlers, for miles, and repeat back for another load..so I quit.
