RE: Is a 22-250 strictly a varmint gun?
I' d say it all depends on where you' re at and what the deer are like that you' re hunting. For 300 lb corn fed deer or the monsters in the North, I' d say no.
If you' re talking 100-200 yard shots at deer in the South where they normally weight anywhere from 75-150 lbs (on the hoof), it' s a fine deer rifle. If it wasn' t capable, I don' t think the game departments would make it legal to use.
