Re: Fixing to pull the trigger
Your decision to get into the LRH game is very likely to be an invigorating addition to your hunting experience. While there are many superb gunsmiths that build excellent rifles, I would use one that understands, and specializes in building long range rifles. As you have likely experienced already, caliber choice is very varied, and based heavily on personal preference. For the range and hunting you describe, the 7mmMag, or 300 Mag would serve your purposes well, and probably be a more practical starting point to learn the sport. IMHO.
