RE: Should i buy one rifle to do it all or two.
Go for a TC Encore wtih a .243 barrel to start with and others as needed. I recently bought a new gun myself and am second guessing myself over did I get the right one. I love it and keep myself from getting too frustrated by knowing that if I'd bought the Encore I'd be doing the same thing in the other direction. So if you're like me you'll second guess any way you end up going, but at least with the Encore buying additional barrels will be cheaper than picking up additional rifles.
