i have an interesting question to the most serious of p-dog hunters here . If you were going to build a rifle capable of making a shot at that distance without luck thrown in what would it be? Caliber? Component used ect: was on a p-dog hunt recently and felt like i had the wrong gun except for my 6mm . Had a 204 and a 8 tw ar in 223 shooting heavy smk . We shot lots of dogs in the 300yd range but the small cals were no match for the winds . Best i could do with a 20mph crosswind was 500 yds by luck. I held almost 8min to the left to make the shot . I realize that there maybe a more inherently accurate caliber out there but if you cant have wind flags in he dogtown and cant get a lazered range what cal would be your best bet? Also i feel that it must be able to group inside a p-dog size target to 750yds to be able to change luck hits into something more predictable . I realize this is a tough question but im looking for insight on making these long range hits . Calibers i have considered are the 6mm rem or ack version, 6.5 284 6.5 x 47 or 6 dasher . Considerations of recoil and flat trajectory to spot misses are also of concern . Any thoughts guys?
