I've had either 3 or 4 7mags can't exactly remember. The one I still own is M70 Custom Super Grade. With this one I had to go about 4.5 grains over a book max. load in order to reach 2900 fps with a 175 gr. bullet. I find its recoil to be more bothersome than a .338 win. mag I own altho admittedly the latter has a muzzle brake.

Today I use a 30-06 in place of the 7 mag even though the 7 is a far prettier gun.

Jim l have worked with quite a few Winchester barrels over the years in 7mm and 300 win mag and have noticed a tendency for them to take somewhat heavier charges to get to velocity as you noticed with your 175-7mm combo.

This is not unique to the 7 Rem Mag.

It may be due to throat length and rifling and might be a built in goof factor to be certain the rifle per ft orms and functions with the impossibly wide range of factory ammo available for popular cartridges. They never know what ammo will br used.

These factors have an effect on the velocities we see and why your rifle might accept heavier ch as rges than those in the manuals for the same veloc ities.

Lik l saud l have akso seen this with the 300 win mag.

Reloder28, not sure I understand what you meant by they are inconsistent? Could you maybe expand on this?

Thanks

Don't want to be critical. I have owned several 7 RM's over the years, worked up loads for friends 7 RM's & talked to several people who have also found the same issues with them. They show a tendency to exhibit sporadic pressure variances. That equals inconsistency to me. For years they may shoot fine & then one day they don't. The last one I had I could not even get past the load work-up stage before it started.


David Tubbs, has also spoken about this cartridge citing the same observation.


Meanwhile, here is an excerpt from a 2003 24CF thread from Mule Deer:
Perhaps a more accurate term would be "wide pressure swings" rather than spikes. It seemingly occurs with about every hunting weight bullet in the 7mm Remington Magnum.

In general, the labs expect maximum pressure swings of 2000-5000 psi with most cartridges, but of course look for the lower as a sign of a consistent load. It's pretty easy to find this sort of spread in most cartridges.

But the 7mm Remington Magnum will swing 8000 or even 10000, and often after several identical rounds have stayed within 4000 psi of each other. And oddly enough, the 7mm STW, which has the identical shoulder angle and short neck, doesn't show the same swings! This indicates that the shoulder angle/short neck theory probably isn't correct.

The problems with the .243 don't show up as much until the throat becomes a little worn--and again, only with bullets in the 100-grain weighr range. Once again, they don't know why.

Despite all this, the 7mm Remington Magnum and .243 Winchester have reputations as accurate cartridges, at least among hunters. I have used both a lot with excellent results. But nobody picks them as target rounds, and the erratic pressure swings are one reason. Oddly enough, if you neck either case up a little, to .30 from 7mm in the case of the magnum, and from 6mm to 6.5mm in the case of the .243, the problem goes away. Why? Nobody knows.

This is exactly the reason I went with the 280 AI and will be getting a 260 in the future and not a 243. Noticeably less throat erosion is also an added bonus. grin

Same here. My Ruger 77's groups shrank by 1/2 consistently and the Winchester model 70's by almost that much. I consider proper glass bedding the foundation of a rifle.

It just ain't hard to get a 7mm Rem Mag to perc if we can walk and chew gum at the same time... (grin).

Anything in the way of criticism that can be said about it....(doesn't give the velocitywith manual loads, loads vary too much, too much pressure, too little prrssure, varies rifle to rifle, blah blah blah) can and does happen with and among others... the 270, 280, 7/08, 257, 30/06, 300 wsm, 7mm wsm,300 win mag 338 win mag etcetc...l have loaded for them all and more and seen exactly the same things in ALL of them

If you jump from magic cartridge to magic cartridge looking for a "cure" to all this, you're dreaming.

If it were inconsistent yhe long range boys vould not load it w iyh heavy VLDs and kill elk and stuff at 800-1000 yards. Too much silly talk about the cartridge....phooey.

For this you don't need a clumsy 26" barrel.

First thing that comes to mind is a Rem 700 stainless SPS, they are not very heavy. Next thing you will need is a Timney trigger for it. A Zeiss Conquest or Leupold VX3 scope and some good quality two piece scope mounts, a sling and case and you should still be within your budget.

I would do what JPro said.. The Remington's long action lets you seat the bullet out where it belongs..

First was an old ADL w blackened SS bbl - shot sub MOA all day.
Second was a BDL SS - 1/2" w 150 NBTs

My next, if I wanted another, would be a T3.

Rather a 6.5x55 or 270. 450 yds would not scare me, prefer a 22 vs 24/26 all day.
23 on a custom preferred for long action or if a magnum.

Met a hard core shooter from San Antonio, prefers the RM vs short 7 Mags, used out to 1K. Seems he had CONSISTENCY.

CONSISTENCY?

I have had a couple over the years and they have been shooters!

Killed a bunch of deer, elk and pigs with mine.

Before I buy one of those I thought I would ask how good they are and if there are other better choices that you all would recommend. My Budget is about 1200. However for a really good buy and quality I can be a little more flexible.

Many Thanks


Your 30-06 with a 26" barrel would be ideal. I have a 30-06 with a 26 e/4" barrel include the brake that gets 2875 FPS with factory 180 grain bullets and 3020 FPS wtih 168.

When I was 10 years old on the playground in 1961, another little boy told me about a wounded bull elk that gored a hunter in the calf of his leg.
Other than that, elk are not dangerous game.
Among ~100 bolt actions analyzed by De Haas, the Rem 700 is the cheapest design to manufacture, while the 98 Mauser is the most expensive. The other bolt action designs are somewhere on the spectrum in between. The Howa is right in the middle.

I am convinced that an elk hunter optimizing for cost is better off with the cheapest, least reliable piece of junk with a quality barrel. [The Rem700]

I quickly and recklessly cut threads and chamber and put an Ebay $35 Rem700 7mmRM take off barrel on a beat up old 1908 Oberndorf Mauser action and beat up old military stock. I welded the bolt and drilled and tapped. It shoots better than I can.

With all the money Rem saves by selling a tube as a receiver, they can put a quality barrel on a Rem700. That is all you need for elk hunting.
