I’ve used both the 6 WOA and 6BR (about as close as you can get) for coyotes with the 70 varmageddon and the 68 avenger. There is absolutely nothing better.
I have a hard time with guys who want a .600 BC to “hunt” coyotes. I’ve shot my share beyond 400 yards, but it’s really impractical to build a rifle around that. Superb point blank accuracy and a wise bullet choice are the most important considerations. This photo is from two weekends ago, all but 2 of them fell to the 6BR and 68 avengers. I run a mild load, so you’re not far behind at all with the 6 PPC.
There is also no need to consider it a single shot. There are plenty of mag spacer kits available, as well as simple tools for bending feed lips.
You are a coyote killin' machine !!!! Well done !!!!!!
