A .270 Win. is quite adequate for any deer. That said there are many more powerful cartridges the .30-06 Spfd., .270 WSM, .264 Win. Mag., 7mm Rem. Mag. and .270 Weatherby mag. are some of the closest to it and you can go on up from there to the .300 Rem. Ultra Mag. and .338-378 Weatherby Mag. as some of the most powerful.





Realistically a .270 Winchester is excellent deer medicine throughout North America be they little Coues whitetails or the huge whitetail and mule deer of southern Canada and the Great Plains. It also works pretty well for elk and black bear with sturdy bullets such as Nosler Partition or Barnes X-Bullet.Is a .270 the most powerful deer hunting gun to use?
Here's a comparison of .243, .270, and .30-06. Any of them are a great choice for deer, depending on your situation. The .243 shoots a lighter bullet, so you may need to be more careful with bullet placement, and the .270 and .30-06 are both available in several bullet weights for all sizes of game.


Here is a comparison chart from Winchester of the three caliber cartridges. There are sever weights available, but the heaviest .243 is 100 grains. I used a 150 grain bullet on the other two calibers for easier comparison.
firstly, learn to spell and type please, it took me a couple minutes to figure out what you were asking, just saying.





anyways, the only reason to buy a new gun in your situation is if your starting to shoot farther then 150 yards, if not, don't get one, if so, then it's your choice.





the .243 winchester is the smallest and ';weakest'; here, but is still a very fine rifle for shooting to 300 yards on deer, any farther and it doesn't have the stopping power to properly take it down.





the .270 winchester is a very fine rifle for taking any game in north america, a little light for moose and brown bear, but it'll do the job, for deer, I wouldn't shoot farther then 500 yards, no point of taking chances with wind drift.





the .30-06 is the most powerful here, some people even say over powered for deer, personally I believe it's perfect, it'll take all animals in north america, from prairie dogs to brown bear and moose, and even take some african field game too. 500 yards is the maximum since wind drift becomes a serious factor after this distance.
If you shop around, there are many good rifles on the market in those calibers. A .30-06 is still the the go to gun if you can have only 1 rifle. It is loaded from 110 grain to 220 grain and will be a good all around gun for North America. A pawn shop or a gun show may be a source for a good used rifle at a reasonable price. Have it inspected by a reputable gunsmith before purchase or look for another one if that is at all suspicious. I still have my Winchester Model 70 from the early 60's and it is a dream to shoot. IMO the .243 is too small for most deer or elk and even the Blacktail I hunt sometimes are over 200 so I go for the .30-06.
There are many more powerful rifles. From personal experience (shooting a .270 and a 30.06 in ';in the field'; situations) I prefer the .270. It has a light recoil and packs a good punch. Its plenty for deer and I have even taken down a 315 pound bear with one. This was using a 130 grain bullet. You can step up to a 150 grain if you want. I would personally buy a .270 if it would just be for deer. If you want to hunt moose and elk and other bigger game go with a 30.06.
If deer is the main thing on your menu, I would assuredly go for the 270. It is a perfect complement to your 30-30, and will take you out of the brush to hunt if you want. It will serve in the brush as well. Also, if you have a 270 in your hands you have no need for either a 243 or a 30-06. Anything that either of them can do is also nicely accomplished by the 270. Happy hunting. J
Like some people have said before me, the .270 is not the most powerful gun! The 30.06, .300, and the 308, just too name a few, are all more powerful. With that being said, the .270 has more than enough punch to harvest a whitetail deer and its one of the most flat shooting calibers you can buy!
Most 'powerful' or adequate.





there are at least a dozen calibers that are more ';powerful'; than the .270.


Of your short list all are proven North American game killers..the 30-06 may be the most versitile...





The 270 is a necked down version of the 30-06 case. If you hunt in any brush the heavier bullet weight of the 30 cal is not as sensitive to deflection from twigs and brush... that being said a lot of elk and deer get killed with .270's every year
personally i'd would go with the 30.06 because it has a lot more stopping power if you ever decide you want to hunt something bigger than a deer like a moose of a elk.


however if you want it only for deer .270 just because it puts the bullet out there a long ways. you can make good shots out to 500yrds if you practice.





good luck
Not by a long shot, but it is a very good deer round. I would get a .30-06 just for the versatility. You can get loads for everything from squirrels to brown bears if you want.





Any of your choices are good.
I am very happy with my .270 for deer and is quite versatile for varmints up to elk and doesn't have the recoil of higher calibers like the 30-06, 7mm Mag or the mac-daddy .300 Ultra Mag.
The 270. win shooting a 130grain is a very very nice deer cartridge
