Absolutely!!! There is a considerable difference between shooting off a bench with a heavy shooting rest .than off a fast & furious rest in the field when game is spotted. Elk are considerably more aware & spooky than deer. They sense the slightest movement or sound. This translates to them moving when you need to place your shot. You would have to keep changing your shooting position. Another point ignored. When shooting long range across a canyon there can be multiple cross winds you are totally unaware off blowing at different velocities & angles. Also up drafts & down drafts. The shooter has no way of knowing. You may have a super accurate rifle but your bullet could arrive several inches off. Elk have a tremendous stride. If an elk is moving at just a slow trot they can move forward 2 to 3 feet before your bullet arrives at 200 yds. depending on the velocity of your bullet. This can mean a gut shot or a total miss, Experienced elk hunters are aware of this. another point totally ignored. Couple all this with a small window to shoot thru which happens frequently ,. Many times an off hand shot is required at close range. Being able to keep all your shots in an 8" circle at 100yds off hand is need to place an accurate shot.... You will see all kinds of hunters shooting at long range targets. How many diligently practice close range off hand??
