I'm looking for a new rifle for hunting but I want it to have plenty of knockdown power at longer ranges. The main rifles I have looked at are Sako a7, tikka t3, ruger hawkeye, and the remmington 700. The calibers I'm looking at are 7mm-08, 25-06, 260 rem, and 250 savage. If y'all could just give me some advice for choosing my rifle and caliber would be much appreciated. I plan on using it to hunt deer and hogs with but also to shoot long range competitions with.
