I'm a hunter. I shoot my guns maybe 3-4 times a year (couple days at the range and a couple actually hunting). Like, less than 100 rounds/year between four guns. So I'm not a great marksman, and definitely not a "trained sniper".

This would be an easy shot for me. At 150 yards, I can shoot a 1/2" grouping, and I have a low-end rifle and scope. You don't have to account for bullet drop or wind at that distance. Just aim and shoot.
