I am going to buy a Remington 700 in the very near future, and I am undecided on the caliber that I will choose. I am buying this gun primarily for hunting whitetail deer, and will do that for the next couple of years. I am simply going to mount a Leupold riflescope and a sling, and then go off to the woods. However, I would possibly like to use the gun for long-range competition in the future, and don't want to be held back by a caliber not suited for the job - such as a .270. I believe the .308 caliber would be a good choice for this type of competing, but I am unsure as how it would perform in comparison to a .270 or 30/06 on American whitetails. I plan to perhaps send the gun off to a custom shop, and get it rebarreled, bedded, restocked, the trigger tuned or exchanged for a Jewell, and new rings added. Would a .308 be suitable for most American game? Which caliber should I chose for hunting now, but suitable for long-range shooting later? Thanks.
