Home Forums Hunting & Shooting Ask The Gunwriters 7mm Remington Magnum?

jc189, I knew a standard 700 Rem. bolt face could be opened up to accommodate a magnum round, but I didn't know you could go the other way. Interesting.

ha, right.

An inch, inch and a half isn't bad for a hunting rifle, especially a magnum. That's minute of deer in my book.

Wooosh !

Right over his head. !!

My .280 Remington will get just under 3000 FPS with a 150 Nosler partition and 56 grains of IMR 4831. But that's through my Chrony which I think runs about 100 FPS hi. But it will put 5 shots in just a hair over 1".

I owned one for about 2 days then traded it.

I do have a 7x61S&H that does what i wanted a mag seven for.

It shoots the 168 bullets to less than an inch and it is not to shabby with other weights.

Only drawback is it weights a ton and is a bench rifle,,of sorts.

And not everyone has one.

This might sound like a cliche, but I trust Chronys about as far as I can throw them--which is much less than 100 yards.

My first .280 was a custom rifle by David Gentry, which I used throughout the 1990s on big game throughout North America, including my biggest mule deer and one of my two biggest caribou, out of a dozen. Used several different bullets and powders, but eventually settled on enough H4831 to get just under 3000 fps with the 150 Partition.

Whether any of that makes any difference is debatable. Have found that caliber, cartridge, powder and velocity make far less difference than the bullet and where it lands.

Ain't none of them magic without those two factors. Yet most hunters keep quoting muzzle velocities, bullet weight, etc. as if there's some consistently detectable difference in "killing power."

Put a longer slow twisted barrel on one and shoot some of the sleeker new bullets and it gives the magnum a run for the money. Same with the 280 & AI.

I’m 46 and a 7RM was my first centerfire rifle 25yrs ago. Still have it and rarely hunt with it anymore. I’ll never sell it. Plopped it in a Ti stock and it’s a pretty damn nice setup. It hasn’t killed a deer any more dead than my 223s.

I’ve owned one 7mm Rem Mag, in the 1980s IIRC, when I was in my 30s. It was a Rem 700 Sendero. My first really accurate rifle. I developed some very accurate loads for it and shot several thousand rounds through it, all from the bench at the range. Never used it to hunt. I eventually used the action to have a 300 H&H built, which I still have.

I am not a fan of the 7mm Rem Mag and have moved to 300 mags for heavier cartridges in this class, and to the 6.5s for lighter cartridges. I find that 7mm Rem Mag rifles are usually as heavy as 300 mags, but IMO don’t offer any advantage. My 300 mags (short, standard, ultra) all propel heavier bullets at least as fast as the 7mm Rem Mag which I believe make them more effective for larger game, without markedly increased recoil. I don’t anticipate owning another 7mm Rem Mag.

The only 7mm I currently own is a 7x57, which I intend to keep because of its classic history and good performance from a relatively small case with reasonable recoil and light rifle weight.

Big fan of the 7 Rem. I haven’t used it a ton the last few years as I like to tinker with other stuff.

I believe it was 458win that said the more big bores he shoots the more he appreciates the 458 Winchester.

I have the same feeling about the 7 rem, the more .284 diameter cartridges I shoot the more I appreciate Remingtons version. The 7 weatherby is my favorite, but it comes with more hassle than the Remington.

I’m 40.

A good point (And well taken) I have been guilty of chasing velocity in both handguns and rifles in the past. I do not own a Chrony anymore. Just don't need it to be successful.

I do not own one, but would like to get one soon. Main reason for needing one is I love guns and like trying out every cartridge I can. The 7mm rem mag is just about the only cartridge that is very popular that I have not tried.

My favorite cartridge for deer is the .243 Winchester and. 250 savage. So I know it's not needed at all, but I've always wanted one.

Also I am 24 years old, but have been into firearms for as long as I can remember.

7mm Remington Magnum is SAAMI registered at:

maximum average pressure 61,000 psi
Overall length between 3.15" 3.29"
Headspace between 0.220" and 0.227"

=====================================

I run:

75,000 psi
3.34" OAL
Build rifles at 0.215" headspace

67 gr RL-26 seemed to be the sweet spot out of my bud’s 26” Sendero with160 NAB’s. Pushing them around 3K, animals couldn’t tell it wasn’t 3,100 fps. They died.

I tried 67.0 in the test rifle, my Mauser M18. It did all right, but accuracy wasn't great--but wasn't poor either. The big star with the 160 ABond was IMR8133. In fact, in general (and again I must emphasize in this particular rifle) 8133 was the best all-around powder.

My 24" Ruger LH 77 in 7 Rem Mag really did well with RL 26 and Hornady 180 GR

Before best accuracy and velocity were the old and dirty H870 with 160 to 175 gr bullets, most other powders speed was slow.


CCI 250 primer RP case (3 @ .56" at 200 yards) RL 26 180 GR Horn ELD (3 @ 1.2" 2 @ .2" at 100 yards} 2938 FPS

I have one, and have hunted it. But it’s too much for deer @nd antelope which I normally hunt.
I haven’t used it in years. In fact my rifle is for sale!

Good info, as always.

Don’t think my bud will swap, but in my 8 twist Brux, may try it

I had a custom 7mm Rem made off a Rem700 action and a 27(ish) inch Proof Research barrel. It's light enough to carry, but not punishing at the bench. I love the 7mm Rem for that reason. It's admittedly the biggest cartridge that I can shoot without a brake without developing a flinch.

I'm 38.
