Before I re-barreled it, this Remington 700 was deadly on ground hogs with the 22-250 Hornady 55 grain V-Max. Top photo, second from the left; the head was completely blown off. I shot the barrel out of this rifle. It probably had 5000 rounds through it. It was only good out to 700 yards because of the light bullet and slow twist barrel. Yet, it was like a laser out to 700. Past 750 it was hard to tell where the bullet went. The last 5 rounds through the old barrel still hit steel at 700. When I got the old barrel back from the gunsmith, I ran a bore scope through it and the first 2.5 to 3 inches of rifling was shot out! Bottom photo was a head shot at 300 yards.55 vmax out of a 22-250, love it. I havnt shot anything since around Christmas with working out of town and bad weather. It came in to 175 and stood behind a tree for a year or two. Adrenaline surged and I sent a bad shot into its leg, it ran off and took a break at 325 where I laid him down.
