Just Lucky,
I have not shot this rifle very much, less than 200 rounds in 22 years, but did shoot it at 500 yards one time from an improvised rest and clanged a steel torso target with 5 out of shots, using a guestimated holdover. I had set up the target for a different rifle, but decided to try the .257 to see how it would do and it pleasantly surprised me.
