30 minutes ago, the wind died down. I dialed in another 18 minutes of elevation and went prone on the deck with my Harris bipod attached.
260 yards, 57 grain LBT bullet 17 inch unchoked barrel, 940 FPS. Energy at 260 yards still exceeds the 25 acp at the muzzle.
4x6 inch 4 shot group, 5th bullet was way too tight so I did not shoot it because I knew it would strike lower.
