I got a Remington 710...it will kill deer just like any other gun...it's light and fairly accurate...for the money it's a fairly good gun.

For a 13 year old I'd say that 270 is a good caliber...if you wanna go lighter try 243 but I don't think that the 710 comes in 243. If someone you know has one ask them to shoot it and see if you like it. Good luck.
