jefdan

    Hunting what? You certainly do not need either for little Edwards Plateau or hill country deer. Maybe if you are hunting nilgai. My choice would be be either the standard .270. Jack O'Connor said it could be used to take any North American game, and proved he was right.

    I have numerous calibers of rifles I have used for hunting various game and varmints since about 1957.

    The standard .270 Winchester is in my opinion the most versatile of all. Forget the hype about muzzle velocity. A good 130gr or 150gr off the shelf round will do anything you have in Texas or N.A. more than adequately.

    Larger bore size, bullet size, and velocity cannot nor will it be a substitute for a well aimed and accurate shot picture.

    For my money, it would be a 7MM Remington Magnum. They can be found on the shelf, right next to the good old 30-06 anywhere in the world.

    The plus of the 7 over the 270 is versatility in bullet styles and weights. Loaded properly the 7 will work on ANY NA game, even the dangerous ones that like to eat human's...even though I would prefer something a tad heavier.

    Best

    The biggest difference between the two is that the 7 mag. has a barrel that's two inches longer and it weighs a pound more.

    I have some beautiful rifles in 7 mag. but find I'm unable to fall in love with the cartridge. The .270, on the other hand, has been a favorite of mine since the first one I acquired in '63.

    EDIT: Sorry--misread! And since I have no experience with a .270 magnum, I'll shut up.

    The original question was concerning the 270 magnums(meaning the WSM, and Weatherby)...not the 270 Winchester, versus the 7MM Magnums.

    I am a huge 7mm rem mag fan. It was the first cartridge that brought me into the long range game and that I learned a lot with,..so it will always hold a place in my house.

    Between the 2,..I would go 7mm simply because of a selection of more bullet weights and styles than the .277 dia. MHO

    jefdan,

    My brother has a .270 WSM and swears by it. The .277 is a good caliber that needs more development by shooters. It's right in that groove of optimal bullet weight vs. naturally high BC. The standard .270 Win is no slouch either, in case your not into magnums that much. But, it sounds like that's the way you want to go though.

    On the 7mm side, the round has a ton of better high BC bullets specifically for long range shooting. This is where I would say the second part of your question is a generalization. 7mm's have better BC's. But that brings us to the first part of your question and that is which is best for hunting in South Texas. I will tell you that for hunting it isn't really going to matter. both have more than enough power for what you will shoot down there. Both have enough power to knock down game at extended ranges of what hunters normally shoot.

    The big question to me then would be what is your backing criteria. How much is the rifle going to cost? Ammunition? That will be the big deciding factor really. How much hunting accuracy you can buy for what you want to spend, and then feed that rifle.

    -good luck

    As you probably know, a .270 is actually .277 inch, while a 7mm is .284, so the difference in bore size is a scant .007 inch!

    Accordingly, the decision between the two calibers is somewhat academic. As was pointed out by a poster, the 7mm has more heavy bullet offerings, commonly up to 175 grains. However, in Texas, if you are hunting whitetails or hogs, I would suggest something more in the 130 to 150 grain range.

    I have used a 7mm Weatherby Magnum in a Mark V Deluxe for years, mostly for elk, but also for deer. It is more than enough cartridge for elk in most cases, with a good bullet. I have usually used the 160 grain Nosler Partition with Weatherby factory ammo, which is advertised at 3200 fps. However, this is probably more bullet than you need for whitetails or hogs, unless the hog is a very large one.

    I am interested in the 270 WSM, and there have been quite a few recent articles written about it. However, again, it is more than enough cartridge for whitetails and hogs. The 270 Winchester is also enough gun, especially with a good bullet.

    You may also wish to consider the 257s and 6.5mms.

    i would go with 7mm rem mag, due to availability on ammo and selection on weights. i just got one recently my self for elk and pronghorn, i love it. i sighted in 3inches high at 100 yards and its dead on out to 400 yards with no distance compensation....love it
