RE: .270 or 22-250
The .270 is far more versatile than the .22/250, which is basically a varmint rifle. although it will kill deer OK with the right bullet, using it for deer is illegal in many jurisdictions, which prohibit calibers under .23" for game larger than coyotes! Yes, you CAN blast varmints with the .270, although it is a bit of an overkill to do so!!
