The 7mm Mag is one of the least efficient cartridges out there. You need to have a longer barrel for all of the powder to burn. That in turn makes you have a heavier rifle. The recoil is also greater than the 270. You really don't have a significant advantage going with a 7mm mag over a 270. A .284 diameter bullet vs a .277 bullet. That's only .007 difference. 7mm Mag factory ammo are also more expensive than 270 ammo too. But in the end, get what you want.


Yea but the 7mm has much more powder behind that round than a 270. Dont forget that part thats like comparing a .177 daisy to a .22


Comparing a BB gun to a 22lr is an apples to oranges comparison and really has no bearing on the 7mm Rem Mag vs the 270 discussion.

You can easily get 3100 fps with a 140 gr bullet out of a 270. Out of a 7mm Rem Mag you can get 3200 fps with the same weight bullet, but burn more powder. 100 fps is not much at all in the hunting world and is basically negligible.

I'd go with the 270 too as the practical approach for a deer rifle. And I'm a varmint hunter at heart who loves big numbers on my chronograph. But once your reach the velocity that a 270 can push the 130 grain bullets(3100+ fps), it's hard to gain much in the way of a flatter trajectory and that's the only gain you might want in a deer rifle. What I mean there is that nobody is going to seriously claim that you need more power than a 270 to kill a deer. It's alway nice to have a rifle that shoots flatter though so range estimation becomes less important.

As my name here implies, I currently hunt deer with a 257Weatherby due to it being - in my opinion - the perfect balance between enough energy to do the job while being small enough in caliber to allow very high velocities to get that laser beam trajectory WITHOUT kicking the snot out of you. But even as good as the 257W may be, if you really look at the numbers for the trajectory with say no more than 3 inches bullet rise above or below line of sight and the 257W gains about 30yds "Point Blank Range" over a 270. Same for any of the other belted magnums. Practically speaking, you gain no performance advantage by going beyond a 270 Winchester for whitetail deer.

But then what does practicality have to do with it? A man NEEDS at least a dozen deer rifles chambered for all sorts of cartridges so we can have discussions like this, right???

Never shot a 270, so I can't comment on it.

I have a 7mm Mag. I have a Limbsaver recoil pad on it. When I first got it, I thought it would kick a lot, and...it doesn't really kick much more than my muzzleloader. I shot 10-12 rounds with it last year in the early fall, and it didn't bother me. However, I would not want to shoot a whole box or two of ammmo.

270 ammo is cheaper, though.

Browning or tikka 270 can't go wrong with it. 7 mag is overrated for around here imo

I see a ton of recoil comments, however I have never shot ANYTHING that kicks harder than a muzzle loader... except a pump action 3-1/2" mag Slug. I shoot a 7mm, but recommended a .270 to my buddy that just started hunting due to ammo price and more importantly AVAILABILITY. I do believe the 7mm performs a little better, but I also believe it is unnecessary in most cases.

I DO NOT believe the opinions about ballistics being nearly the same. Everyone comments that the same bullet weight and nearly same caliber shoot nearly the same ballistics... impossible! The laws of physics proves if it is nearly the same bullet diameter and the exact same bullet weight... if one kicks harder then there is more energy in that bullet in motion. Period.

You hit the nail right on the head.

And all this time I thought I had a 7 Mag because I got a helluva deal on the rifle. Silly me.

Shoot what you want; simple concept.
