Re: switch barrel caliber selection
NY700:
The 308 vs. 30-06 debate is old and hashed, but here's the finer points that I continue to "copy paste" as a response.
Given equal barrel lengths, the 30-06 will run 250-300 fps faster for damn near everything on the 308. My dad and I have matching rifles, matching parts, everything, except he built his in 308 instead of 30-06. Across the board I get 250 fps or more on his, and I worked the loads for both rifles.
110 Vmax 3600 vs. 3275
150 FMJ 3150 vs. 2850
178 Amax 3000 vs. 2725
208 Amax 2885 vs. ???
That heavy 208 Amax load runs almost neck and neck with a 300 WM.
Ammo for either caliber is in every backwater hardware store, grocery store shelf, etc. If you get out on a hunt and somehow ruin or forget your ammo you can walk into just about anywhere in this country and get 308 or 30-06 ammo.
The 260 running in a LA will do just fine and it will allow you to mag feed even the longest rounds you can put together.
The 280 AI as well as the 284 Win are probably going to need some massaging to make them reliably feed from a standard action.
The 280 Rem is not as prevalent over the 30-06 but it isn't unheard of. I'd vote for you to keep a 7mm round if you don't already have one. If you're going to hunt with the rifle a lot though, the 30-06 will probably suit you the best, especially in the "oh shit" situation where something is lost/forgotten/ruined.
I have shot my 30-06 to 1400 yards so far, I'm hoping to make it to a mile this summer.
