No range finder, he's praying before he tries the shot.
There might have been some praying involved. Had to do lots of ranging since we were shooting about 40 different targets on both sides of a canyon. They were between about 200 to 660 yards. If I could have mastered my smart phone like the cool kids I would've taken a pic highlighted the targets and given them yardages.
This was at a Cabelas/Magpul long range precision rifle class last summer. Had Marine scout snipers for instructors and the two gunsmiths from the Remington Custom Shop that built the rifles to keep an eye on us.
I learned a bunch and made some improbable shots all the while making some new friends.
Both Cabelas and Magpul had photographers there and the told us we might end up on social media or in ads. I wasn't expecting to see myself since I'm as photogenic as a cow pie.
