I have Both and plenty of other calibers. I would go with the .308, simply because you have a much better number of bullet weights to choose from. And the .308 is a favorite of the military and police snipers because of its inherent accuracy. You can get the .308 in short , fast handling rifles or in regular length stocked rifles, and I personally love the shorter rifles. They are lighter and easier to carry. But, as many have said, the .270 is a fine rifle round...... I just think for your applications the .308 is a better choice. And if you decided you needed more power, you can buy some Hornady light mag sst ammo, and it will do anything you could ask of it.

In rifle choice, the Ruger M77 ( full size or the new Compact model ), Browning A-Bolt Hunter or Medallion ( or the A-Bolt Micro Hunter in a short gun ), or the Remington Model 7 for a short gun are super rifles to choose from. And yes, I do own all of them plus other brands and models, but those guns see most of my hunting action. I would highly recommend you check them all out and pick which ever feels best to you. If you have any specific questions about any of them please feel free to PM me.

Good Luck,

God Bless
