I was at a gunshop today in Findlay, Ohio that sells mostly shotguns, but they had a Remington 700 BDL with a scope on it in 270 Caliber and they were selling it for 400.00. Really nice rifle and in almost perfect shape, but it was an older rifle when Remington were at the top of their game. Their is not one person on this forum that can say that the 270 isn't a nice deer rifle. Its second only to the 30-06 in sells, but alot of people buy other calibers.
I guess what I'm saying is that this hold subject is subjective in nature, whats that old saying "one mans junk is another man's treasuer.
My 7-08 took to big whitetails in Wyoming that weight in at 220 and 230 lbs. and they were shot at 413 yds. and 417 yds. and the round drop the one at 417 yds. right were he stood and the other went 50 yds. and drop. You really can't ask a rifle or cartridge to do any better then that. Can a 308 do that, yes, can a 30-06 do that, yes, can a 270 do that yes. If the person behind the rifle does his part. These are extreme shots and most hunters will never take that kind of shot in their life.
To sum this whole think up, just make a budget of what you can spend, lets say 400.00. Ok, now go out and shop and I mean shop, don't be in a hurry. Remington, Howa, Tikka, Savage in the above cartridges. If you fine one in your price range in the above cartridges buy it. They all will do an excellent job for you, but for god's sake, don't second guess yourself after you do it. Buy it and go out and shoot as much as you can afford and enjoy it and they go hunting.
