Home Forums Hunting & Shooting Long Range Hunting How come the 7 m/m

Rem Mag or Weatherby or RUM or STW are not talked about as good long range shooters? Are they just all old news?

No, they've just been talked about to death already.

They are fine long range shooting chamberings just not the newest thing. If I were to do one up I would do an aftermarket barrel though to ensure a good chamber from a sharp and to spec reamer. I understand that the bad rap for erratic pressure the 7 Rem Mag got was due to tight chambers from dull reamers trying to keep up with production demands. Also with a semi custom you can get it throated and twisted the way you want and a magazine box that will fit what you want. All things that the original manufacturers overlook.

I visited with Best of the West in Cody... The 7mmRM is one of their top sellers, second I think.. 300WM is first I think..

Wait for the 7 creedmoor......

I think with the increase of optics and the guys who can actually run a scope with turrets properly, coupled with rifles with a fast twist and heavy bullets can achieve arbitrary LR range killing without much ado. 😎

The 7mm Rm is as good as it ever was - which is to say it is good well past ranges where most shots at game are taken. A 150g LRAB at 3000fps at 7000 feet will retain over 2100fps and 1500fpe at 700 yards. And it will do it with recoil about the same as many .30-06 loads.

Not too shabby.

Where did you get that from?

28 Nosler pushing a 195 gr Berger at 3150 fps

This is why I asked being they have been around, proven, wrung out from every angle, etc, etc I just thought there would be some 7 mag fans to issue their findings on the long range issues. Oh well I guess I am late to the party as I recently acquired my first 7 mag and am going to wring it out for said purpose. Thanks

BTW the brass is still very reasonable AND available..........

I love playing with the 7 mags. I`ve two chamberings, a 7 Wby, on a 700, and my third 7RM on a 700. The wby is in a 26 inch 9 twist PAC-NOR barrel, H.S. stock. I shoot bullets from 160 up to 180. out of it. Longest shot on deer was 465 yrds, longest on a water jug 1K. That thing just works,,,so there is not much to say about it.
The 7 RM`s were set up just to fool with...see what I could do with them. I bought take off barrels from the guys here on the 'fire", had my smith push out the throat on the first to wby lead dimentions. Found I could easly duplicate my 7 Wby velocities using cheaper brass. Also played with a "factory" rifle. Standard everything. IMHO the cartridge is very limited for velocity with heavy bullets by the short lead, but shot well. I didn`t like that, so on my next 'new' take off, I compromized in throat length, and only went out .375 inch, tapered lead. I want to utilize the ELD bullets, so as throat erodes, I can chase it a bit. Just got this rifle back two weeks ago, haven`t been able to shoot it much, but the first several three shot groups at 100 have gone very well. I`m using RL-25, 162 ELDM at 3050 fps., 26" barrel, 9.25 factory twist. My 700 yrd range is snowed in right now, expecting 10" more tonite, so may have to wait a bit before I can push it out a little.
Like the guy said, they worked, real well, for a long time, so what`s to write about?
Good Luck with yours`.

CGPAUL,
Let us know how the new one works out.................................

7 rem

Try a throat around .200 for the 168's
.250 for the 180's

Use R26 and berger hunting bullets

My throat on mine is still std dimension.... but I have a stock of the old 2 diameter 150 & 175 gr Corelokts that I will load with an old batch of 7828 and H570 & H870 to see if one can actually hit those 1962 velocity figures. Also have a 26" ss take off barrel to replace my current one when it goes. MB

Will do....going to try some 168 Bergers next. The weather the next few days looks like crap..hopefully, next week.

I have a Vanguard Classic II in a 7Rem Mag that I believe to have the 24" Weatherby 7Mag, 1:10 twist. It has a considerable amount of "free bore" and takes about 2-3grs more powder to equal standard Rem 700 velocities. It is very accurate with most any reasonable load, otherwise I would have gotten rid of it years ago (awful loud and considerably heavier than my .270). I also have a 26" Encore in the same 7Rem Mag caliber with a much shorter throat; I have to make sure I don't mix any of my Vanguard's "max" loads! I too believe most of the reported "spike" loads were caused by varying chamber dimensions, or throat lengths made by manufactures that might have extended "tooling life" a bit far (no, I do not have proof, but in 30 some years of loading this round I have never experienced "unexplained" pressure spikes.) Otherwise, how can you conclude that the same case that is used in the .338WM and .264WM were never known for having "pressure excursions". I suppose that it is possible that cases made for the 7RemMag may be "softer" than that made for its smaller and larger "brethren", but I doubt it. I cannot imagine changing the bullet diameter in either case [necking up or down (with "neck turning")] would cause a "spike" unless other factors were involved, ie. chamber, throat, lead taper, etc. I also think that by "fire forming" new 7Rem Mag brass by necking up to .30 caliber and necking back down to 7mm until it fits in your chamber will correct any "head space" problems you might experience. ("Gun Scribe" John Haviland takes credit for this bit of modification to extend the life of the, normally, short life span of 7RemMag brass; thus, head spacing on the shoulder rather than the "belt" from the "get go".) I've have done as he suggested, but have not shot enough of the rifle/cartridge lately to report on cartridge longevity. BTW, my Vanguard loves IMR7828 and RL22, especially with 160 and 175gr bullets; my Encore likes the 139 and 140gr bullets best. Sorry, didn't mean to "hijack" the threat; for it is a great long range shooter.

Just one of the many excuses I have heard and seems to be the more common one that I’ve heard. Even here so it must be true😀. I have never experienced it myself as I’ve never owned one but at a glance it seemed to make the most sense from other explanations I’ve heard. I have TALKED to people who have had both mass produced 7 RM and custom barrel ones that have claimed it made a difference. I’m sure there’s more to it though. Either way if I were to go 7 magnum anything it would have a custom barrel,chamber,throat and magazine box so I could shoot 175+ grain LR bullets properly. The 7 Remington Mag is a fine cartridge but it’s been hamstrung in it’s commercial wrapper and deserves better.

I didn’t read your full post until I responded to mathman. But I agree with your points when comparing it to other rounds based on the same case. What makes the 7Rem Mag any different other than it’s a victim of it’s own success.

I own 2 Remington 700’s in 7 RM. my first one I call my End Table (BDL Deluxe DM) it shoots factory 160 Partitions at 3/4 MOA out of the box. Only thing I’ve done was lighten the trigger to 3#. My other 7 RM is limited run Boone and Crockett edition. 26” factory fluted barrel. I’ve glass bedded the laminated stock and lightened the trigger to 3#. Has a 5-20 Huskamaw on top and shoot 1/2 MOA or better with factory 150 Core Lokts. I’m finally getting around to hand load for this one. Weather hasn’t be good. Will see how it does with 168 Berger’s first. 168 LXR’s are next. 7 mags do everything I need on the big end and my .223, .22-250 and .25-06 handle the rest.

They shoot one hole groups...boring!
