Pretty sure it’s pinned….but don’t bother, I’ll go back through the thread. Don’t remember the CC version even mentioned but will check again since you’ve straightened me out.
Most accurate SR25 I've seen was in a 14.5 .308. I've shot my 16 ACC to 1000 without issue. The 14.5 is more then enough for your use at 300 yards. Even at 700 it still hammers. 14.5 is noticeable vs the 16 apc when in your hand. Jusy unpin the MD and pin on another. No need to be chasing KAC stuff right now that doesn't exist for sale anywhere.
