As to the topic of the post...
In 2020 I shot 4 elk, all with a 7-08 and 140 accubonds, fired exactly 4 rounds to accomplish it.
Ranges were: 30, 278 yards (held 20 inches of wind and it was just enough, just), 108 yards, and 162 yards.
I was standing next to several other people this fall that also shot elk.
My Dad shot 2 with my 7RM and 140 E-tips, both elk at 250ish yards, 2 shots for the bull, one shot for his cow.
2 friends killed a spike bull and 5 point bull with 7 RM's...one with a 150 grain blue box federal, one with a berger (thinking 180 grain?). Another friend shot one with my 7 RM and a 140 grain e-tip, one shot, 200 yards.
Another buddy shot a cow with a berger of unknown weight from his 300 winmag at 550 yards.
Finally, my youngest nephew shot a cow at 362 yards with a .243 and 100 grain nosler solid base (luckily I have 4-5 hundred of them), one shot.
As per always, the 3 most important things to killing elk are:
1. shot placement, 2. shot placement, and 3. shot placement...roughly in that order.
