Home Forums Hunting & Shooting Ask The Gunwriters 7mm Rem Mag Vs the 270 Wby

Hey 257Bob....Guess I should qualify that comment. The 130 hornady I had trouble with was probably pre-Interlock in factory Wby ammo. In particular I shot 3 150 to 160 lb whitetails at ranges from 100 to 175 yds on quartering away angles through the ribs and failed to get an exit on any. Two were very difficult to find without a blood trail (Ala. pine plantation/thick) and the third wasn't found for a week about 300 yds away. After going to 150 gr Interlocks the penetration problem went away.

shootem, thanks for the clarification!

I'm assuming you're shooting smallish FL whitetails? Nothing wrong with shooting what you want but you certainly don't "need" more than a 243...

I had a couple of boxes of 270WM Norma factory loads using 130gr Hornady Spire Points - I have never seen anything drop a Sitka blacktail like those things.

Having said that, I have settled in on 150gr Noslers - Weatherby factory loads - that really shoot well out of my rifle.

nope, GA whitetails up to 200lbs but most around 170-180. my 257 wby is really fine but I have the itch for another wby and the 270 is as high as I will go (don't care for much recoil). also, my 243 (the 240 wby version) is a dandy.

My 7mm Rem Mag shoots 150 grain Nosler Partitions into a 1/2" group for three shots at 100 yards. Don't know the velocity, but the load is 63.5 grains of H-3831SC with Fed 210M primers.
Last week, my son shot a Whitetail Buck with it that defined bang flop. The bullet broke both shoulders, and destroyed the lungs, with the deer falling sideways straight down, belly up. No movement what-so-ever after the shot.

I still say you should try some 120's in your big 7. Try both the 120 TSX and the 120 NBT ran with R22 and you will be very happy!

And of course you're right, for deer of that size and for the ranges you're normally running your 243 is a great plenty.

You musta been reading my mind...I just picked up two boxes of 120 TSX's, a pound of Re 22 & ALSO got the LAST box of CCI 250's (1000)count...feelin pretty good...especially about the primers...

They will rock big time, and for serious accuracy in that big 7 some time give the 120 Horn HP a try with R22. I have shot some teeny tiny groups with said combo over the years.

Hmmmm I'm not sure I agree with your statement. My load for my 7MM Remington comes out of Hornady Vol. II. It's 3400 fps with a 139 Gr. Hornady and 71.4 Gr. of H4831 that's out of a 24 inch barrel. Doesn't sound like .270 WIN. performance to me.

I load my brothers 7RM with 71/H4831 and Hornady 139 and it smacks down deer size stuff as good as anything!

I shot a 7RM for years except with 160 Speer hotcors.

I had a 270 Weatherby that was not as accurate as my 7RM but in all fairness I bought it used thinking a bedding job would make a difference. Maybe the original owner sold it for the same reason I did. At any rate I would love to have an accurate 270 WM. Except I would not get rid of my 7 RM it is like an old friend.

"Hmmmm I'm not sure I agree with your statement. My load for my 7MM Remington comes out of Hornady Vol. II. It's 3400 fps with a 139 Gr. Hornady and 71.4 Gr. of H4831 that's out of a 24 inch barrel. Doesn't sound like .270 WIN. performance to me"

Have you run that load over a chrony? on paper, that's excellent performance.

Just so happens that I have some hornady 120 HPs and about enought RL22 for 10 rounds or so, not to mention a few pieces of brass laying around for the 7mm. sounds tempting...

I shot a couple of boat loads of chucks with that combo and it worked very well.

I'd try it, if it perked and I can't imagine it wouldn't then I'd try the 120 NBT and 120 TSX.

I am telling you I can help you save some coinage here...

i think the 264 win mag is an excellent idea

Heres the rub I guess. I cannot tell you within thousands, how many animals I have killed whereas most authorities can state an actual number, usually from a few to a few dozen.

My personal record, at least one I can remember, was 100 kills in 3 hours during a cull. Usually we counted the misses or the animals that required more than one shot then counted the cases we went through at the end of a hunt to work out the numbers. Mostly, we shot and moved on looking for more.

Let me give you an example. I hunted a large property where the owner had never seen his own back fence. These properties are measured in millions of acres here. I wanted a particular species to hunt. The typical retort from the property owner was to name several other species and order us to kill everyone on sight. If he did not find bodies on the ground we would not be welcome back.

That my friend is bullet testing medium.

We are talking deer sized animals here which is why the .270 Weatherby was compared to the 7mm Remington. I already stated my feeling was that the .270 bullets being manufactuered for the standard .270 Winchester was most likely the reason for the faster kills compared to the 7mm.

I am very comfortable with someone else having a different opinion because it does not detract from what I experienced.

The 7x57 using the lighter weight cup and core bullets offers enough velocity to open game bullets in that caliber and performs along the magnums in that caliber up to most "usual" hunting distances. The fact that it has mild recoil and a soft report compared to the magnums means that most hunters shoot it very well neither being intimidated by the baggage of the magnums.

What makes my comments relevent is that these observations were made during my most magnum oriented period where I was pushing velocities to the limit and going up in case capacity and bore size until animals dropped with no tracking whatsoever.

The 7x57 stands out in my cerebral HDD because during that time, I noticed animals falling over to the shot, over and over again, which was exactly what I was trying to achieve using the medium magnums.

That is the very reason I went back to the 7mm Mauser.

I'll say it again, in my experience, on deer sized game, the .270 Weatherby kills game more emphatically than the 7mm Remington. Emphatically, by my definistions means that for every hundred animals you shoot, there is a higher percentile that respond similarly to the shot.

AGW

Yes and in my 26" barrel 7MM it's over 3450 fps

AGW-perhaps I missed it but what bullets did you use in your 270 Wby and the 7 RM and the 275 Rigby?

And at what kinds of ranges did you do most of your work?

Dober

Aussie,

In addition to Mark's questions, could you describe the terminal differences you see between "efficient" and "emphatic" effects on deer-sized game, when both result in an animal falling over at the hit?

Also, have you seen significant differences between the 7x57, for instance, and the class of cartridges just below it, like the 6.5x55, the 257 Roberts, and the 243 Winchester?

Thanks,
Jaywalker

So, while you said the 270 Wby kills more "efficiently" what you really meant is it kills more "emphatically?"

Not a bad thread. Has kept on point for quite awhile. Waiting for AGW to write about the 6.5's, .257bobs & .243's. Got a new batch of popcorn ..... just waiting.
