Bergers are surprising
Have a 300 RUM setup for shooting out to 1000yds. My buddy has a 7 RUM setup very much the same. We were shooting on the weekend at coyote silhouettes cut from 3/8 inch steel. They were set out to 500 yds. His 7 RUM with 168Gr. VLDs punched clean through at all distances. While we didn't measure, his holes were almost double diameter and looked pretty much the same at all distances. It was amazing.
I was shooting 180Gr. Swift Scirrocos and they only punched through at 400 and 500. At 200 had a few bullet jackets stick in the silhouette but the lead went through (didn't think that was supposed to happen with them...).
