Hello 500Nitro,

It's mostly me. Temperature was about 15 degrees. I was shooting off my elbows, on the bench, ever-so-slightly touching the back of my hand, on the front rest to help steady the rifle. With only a 2X Leuplod scope, it was difficult to get a real "fine" sight picture, especially while shivering. I was mostly interested in measuring the velocity before I loaded a bunch of ammo.
