For loooooong range 223/556 which 77 grain do you prefer, the matchking or the custom comp? I'm currently using the matchking, they are getting the job done but I'm always looking for a better mousetrap.
Also I'm using 2000mr but found out it's very temp sensitive, same load, summer vs winter is between 200/300fps difference. I'm doing this of memory so it's not super accurate info, winter 2554fps, summer 2780fps with a max load getting 2900fps out of a 20 inch barrel
