Nice choice. Assuming that's a 16" barrel, you may not get the full performance out of a .224 Val. 20 - 22" barrels are pretty standard on .224 Vals. 1,300 yards is at high elevation. 1,000 yards is more realistic at sea level.

A .221 Fireball upper would also be fun (albeit expensive to shoot). Whisper quiet, no recoil and 4,000 fps standard (I've heard you can push 4,500 fps). Not a super long range shooter per se, but if your staying inside of 500 yards, it would split a frog's hair in two.

Have fun.
