Home Forums Hunting & Shooting Hunting Rifles 270 wsm or 7mm rem mag

Some people can't figure it out.

For those that can, Kimbers are bliss.

It's not that hard.

How does that make the 7mm Rem Mag "wrong"?

I could say the same thing about a 280, 7x57, 270.....etc and say the 7/08 is all wrong..

Or I could say the 7/08 sucks if I want to use 175 gr bullets.which a 7 RM handles far better...so....

Funny how people use a cartridge a couple times and suddenly everything else except their pet cartridge is "wrong". That's an emotional analysis.

I love these magic cartridges that make everything else "wrong".

I don't recall the OP asking about the 7/08 or the 280AI....... it's a real chore to stick with the cartridges the OP asked about without interjecting other opinions but that's common around here....

I once did a study of ballistics comparing the 7 mag and the 7mm-08 at 1000 yds. What I found very interesting was the fact that once you push a bullet beyond 3000 fps it sheds an exponentially more amount of velocity due to increased forced on the tip of the bullet. When reaching out at distance there is a lot less difference between a magnum and non magnum cartridge than one might believe.

Concerning the 7 mag vs the 270 WSM I'd take the one that was a great bargain in the first rifle that came along that suited my fancy.

Back in 1982 I chose the 7mm RM. Never felt the need for anything WSM.

Someone mentioned WSM cases can go for a lot of reloads. So can 7mm RM cases. Cases extracted from my 7mm RM have a tiny scratch on them, making it easy to count how many times they've been chambered. By running slightly less than max loads I've had cases go 18 times.

Not saying the .270 WSM is a 'wrong' choice, just not what I would chose if doing it again.

Vanilla 270 in a 6# 7oz package.

' course there's been no mention of bullets or distances.....

With handloads only the belted 7mm RM design requires delicate FL die settings to get their belted case web to last many sizing s.

On the practical side the veteran 7mm RM has been around for decades and the WSM s were made to sell just one more rifle.

The big difference is that the 7 mag can push heavier for caliber bullets at speed and be more effective (less drift, greater energy) at long range. In that instance, velocities are 3000 fps or less. Advantage 7 mag.

I have the following in my safe:

Merkel K1 single shot in 7mm RM: 6# 8oz scoped.
Rem M7 AWR 7mm SAUM: 7# 1oz scoped.

My K1 is my lightweight stalker and I used it exclusively in Africa on my last trip. It has claimed Plains Game from Springbok to Eland. This rifle fires a 150 E-Tip at 2,900 fps. It groups in the 3/4 MOA range. Ammo is available pretty much everywhere.

My Rem M7 AWR is my foul weather, Alaska rifle. This rifle has claimed several deer, a couple hogs, my Mountain Goat and two Sitka Blacktails. This rifle fires a 140 AB at 3,000 fps. It too groups in the 3/4 MOA range. This is a handloaders option only as SAUM Ammo is pretty much non-existent.

Is there any real difference in trajectory and killing power? Probably not. The two rifles for me are really about purpose and the type of hunting I'm doing.

If I had to pick one of the two I'd probably pick the 7RM for the ammo availability. A 7# all in RM is an incredibly flexible tool. The RM does offer more case capacity and range but really, does 200 fps really mean all that much?

162's at 3K is about as good as it gets. Take that bullet out of the equation and you've got a lot of things that are in 270'ville. Like it or not.

I'll take 110 TTSX at 3,400 in a 270 over 120 TTSX at 3,500 in my 7RM. 140 NAB's vs 160 NAB's same thing.

Numerically speaking and sans a little energy.


But nothing lives with a Corlokt in its lungs either. Go figure.

Works for me.

What's the Fact the it was introduced in the 60's got to do with the reason the cartridge was brought to market. Weren't all cartridges introduced to sell more rifles???

270 got anything like a .754BC at 2800+?

Read the entire post.

But sure, take that and you've got a little more drop, less drift (+/-1"@500) and a coupla hundred FPE over the 162. Start looking under 160 in the 7mm and you ain't gaining much of anything that matters.


Yet no mention of bullets so who the hell knows.

If you're going Seven Mag.... there's no reason to look at anything under 160s....

If you wanna shoot a 140... do it in a 6.5....

....+1......And for those who prefer the 7 mag, why would one need more bullet weight choices (which granted the 7 can offer)?.....For deer only?

270 WSM gets my vote here.

Pass the 7 Mag every single day and twice on Sundays...

I love these threads.......

Lightweight to me is the 6# all up class...in that case neither--more along the lines of what Dog said.

If lightweight is 7# ish then the mag. I can live w/o the 270 caliber.

Me too... Always kinda' cute to see the .270 guys try to make them as good as 7s...grin
