I am putting together my budget build, shooting for somewhere near $1000 for the rifle. Going to put a Mcgowen barrel on a savage action, bed it in a B&C or Choate stock, and then put a vortex viper on top of it. But I am posing a couple questions, and this is where I am stuck. I want a gun that I can shoot out to about 700 yards effectively on game. I dont really see myself shooting much farther than that at live animals...just yet. But I also want to be able to capatilize on a 100 yard shot if it surpisingly presents itsself. So far, here are the calibers that I am contemplating...and why. Also, I will be hunting for mostly deer sized game, but also may use the rifle to hunt elk. 300 win mag: Tried and true, packs a punch, readily available supplies 338 win mag: Ballistically very close to the 300wm, heavier bullet, little bigger hole, and I have seen the effects and anchoring abilities. 300 wsm: I like the idea of a short action, and wouldnt mind trying this caliber! 6.5x284: The new hype, seems very promising, very accurate. Cons are that its a little harder to find stuff for, and short(ish) barrel life. I also really considered going with a 308 because I thought it would be good to get started with, but I dont really want to discover that it would be underpowered for game once they are out there a ways. What do you think I should do? Any suggestions, ideas and comments are very welcome! Please Help! Thank you!
