This is my first PD shoot so I really do not have long distance guns. I am going to have along a Ruger 77/17 and 2 - 223's. I hope that the one will be a consistent 400 yard gun, but the only proof is in the shooting. It is set up to run 40 grain V Max at just a touch over 3700 fps. I would be 4" high at 200 yd and 10.8" low at 400 - in theory. I know if the wind is blowing real hard, I will just be a guessin' a lot. If I do another one, I more than likely will have some thing with a little more range to it. I have been thinking of a 204, 22-250 and maybe a 6mm BR or a 22 BR. I have a Remington 700 with a 221 Fireball barrel, but I do not see that it would benefit me much in OK. It works great around here, but I just do not get much long distance opportunities.
