This has nothing to do with caliber and everything to do with you.I want it to be elk capable for 600-650 yards.
280 AI will be in my safe when I get back into reloading. I sold all my stuff 10years ago when I moved.I'll throw the 280 ackley into the mix. Less powder and recoil than the prc and has decent factory offerings.
308 is a great choice too. I have a Kimber Montana that has had the barrel cut back to shoot suppressed. The gun all up is like 6lb 6oz that’s with a trijicon accupoint 3-9, SiCo scythe and warne mountain tech scope rings.Every time I see one of these thread’s pop up I want to say 308 but sadly I have to agree with you.
