Well you guys have fun with the magnums. I'm a big fan of the good ol' American standard .30-06! My next project gun is going to be a LR mauser based .257Bob AI. Everything I have read on the ballistics of that round makes it the best cartridge to go improved on. The gains are worth it, and Ackley shot it himself always proclaiming it as his favorite, too. I do love my 6mm Remington though, but I also have a .243 which pretty much is a clone ballistically.
I do reload and once I find an optimal round for the gun I only load those. I write my own ballistics cards for each round and gun too, I hunt a lot of hill country and having all the numbers to account for wind, angle, drop, and anything else you can think of makes sub MOA very consistant. Both my dad and I are in the 1000 yard club with confirmed kills on coyotes. Kinda a crap shoot with non magnum cartridges at that range though. I'll call it luck any day over flat out skill.
Happy hunting Big!
