.270 has recoil??
You want recoil, try shooting a slug out of a rifled slug barrel on a 12 gauge wearing a t-shirt. Or a 7mm mag. I've shot both. 5 rounds of slugs is enough fun for me for one day. A box of 7mm is all I want to shoot at one sitting too. I've shot .270 and 30-06 for 40 rounds (2 boxes) in one day a couple times, no problem. Of course, the gun has a lot to do with it, I know someone with a "featherweight" .308 bolt action (light weight, short barrel) that sucks to shoot (same as or worse than slugs out of a rifled 12 gauge).
I love the 7mm (prefer Weatherby over Remington), but it's a bit overkill for anything around here and it's a bit pricey to shoot (a box of factory 7mm weatherby mag goes for around $60 around here, when you can find them).
.270 rounds are common (more so around here than .243) and a pretty good round (especially with premium bullets). A .270 is essentially (not exactly, but close) a necked-down 30-06 cartridge.
