OK, before I invest in two or more bolt action rifles (.308, .223, et. al.) could the .308, loaded by hand with various bullet weights, powders, etc., serve the purpose of a long-range Tactical rifle, a long-range Varmint rifle, and a good medium game rifle? Would it require me to have different scopes, then, to track properly with the loads for Varmint vs. Tactical vs. Game? I always have more scopes than rifles, so that wouldn't be a problem if I had to do it that way. However, if the .308 won't do the trick as a Varmint rifle, should I get the ever-popular and ubiquitous .223, or some other whiz-bang round?
