Ok, here's the deal with this one: I have a New England Firearms .308 Survivor rifle. I am looking to upgrade to a Remington 700 SPS here in the next month. I have come up with this dilemma, and I am having a hard time making this decision for myself. I have lots of .308, hundreds or loaded rounds. On top of that, I have lots of reloading components (brass and dies), that I would loose if I went 30-06. My question WMD, is the 30-06 caliber really worth it? I have other rifle calibers, and down in Texas there is nothing aside from a cow that I am worried about with the .308 (a 30-06 is not any better for this application really). This is probably the last firearm I will be buying for a LONG time (many years). The rifle will cost the same, but I would need to spend at least $400 to get all the ammunition and components to replace my .308 stockpile. I'm liking the fact that 30-06 still has surplus available for it, but so does .308. The only ammunition shortage I see with the .308, is the M-61 penetrator rounds are completely absent from the market, if that is your cup of tea. The .30 cal AP bullets are impossible to find for sale too, so the 30-06 only has a small advantage there. Not that I will be shooting them at any deer, but it is sometimes fun to shoot the old rusty crap on my friend's ranch. Well there it is guys, my dilemma. I'm hoping that maybe someone on here will have some ideas. I'm sure I will end up getting a .308 anyway, but this is some brainstorming of ideas. This is mainly an excuse for starting a thread, possibly to debate these two calibers.
