First of all, I've been shooting .270 my whole life and don't reckon I'll ever change, so long as I'm hunting North America. That's faster than ALL of the big 3 loaded 130grain loads I've shot out of two different 22" barreled rifles. Unless you are putting lots of rounds thru a very hot barrel, a shot out 270 barrel is pretty rare stuff. I have seen figures of 1500 rounds for 243, 5000+ for 308, but I would expect a smooth function of barrel life versus bore size on this same case. You will also save on powder due to the smaller case size. Obviously this doesn’t happen, so what’s going on? To fully geek out on this, I was reading Ken Water's Pet Loads last night, a great book by a big shooter and hunter that gives a ton of historical load data (real and still sometimes useful load data from the 70's and 80's but giving a great history of most of the cartridges he talks about going back to the early 1900's)... My 22" factory barreled 270 Win shoots 140 grain factory ammo around 2950 fps. Recoil is a bit lighter with the 7mm-08 than the 270 if loaded with a 130gr bullet on factory ammo. It’s unclear exactly why Winchester decided to go with .277″ instead of .284″ bullets with the .270 Winchester. I also have a 26" #1 contour 270 barrel on order from Kreiger, which will arrive too late for this year, but my plan for this winter was to build a 270 that got near 7mag velocities. So my vote would be for the 7-08 over the .270. This might be possible with a tiny dentist’s mirror, but a Hawkeye Borescope from.
