Re: 7mm RSAUM vs 7mm WSM? I need help!!

Is there something you don't like about the 7mm Rem Mag? Do you reload? Usually a 7mm Rem magnum can be made into a competitive shooter. It is also a well proven deer round - though I would not inclined to shoot at a deer at 800 yards. At lease not without a lot more practice.

If you are not set on buying a new rifle, my I suggest the following:
Buy a great scope: Night Force, S&B, Premier whatever;
Buy Badger bases and rings;
Either sign up for a rifle class or start shooting F-class in your area or both;
Replace the stock with heavy duty fiberglass stock;
Wear out or at least put a lot of miles on your barrel;
When you decide on the final manufacture, caliber, contour, of the barrel you want, plan on 6 months leade time for ordering the barrel; Sent the package to a good gunsmith to do your build.

Good luck

Re: 7mm RSAUM vs 7mm WSM? I need help!!

IM in the process of building a 7 RSAUM myself. To me the case goemetry seems better on the SAUM. I like having the longer neck too. To me the case looks alot like a 6.5x47 Lapua on roids. I bought a 250pc or Rem brass and did a quick weight sort of about half and was pretty impressed.

From what Ive seen on some of the competition shooting forums, it does seem to me ths SAUM is gaining favor.

good luck with you project

7mmSAUM is going to be my next build... just waiting on funds

The case itself is proving to be more efficient then the 7mmWSM, which over time means savings in powder and possibly barrel life.

M2, my advice to you is that you need to get your 7mm mag shooting well out to 1k.

Why exactly is it that the rifle does not shoot well? Are you 100% certain you are doing your part and the rifle is failing you?

Remington actions and barrels generally shoot well. Sometimes they get let down by a bad stock, and sometimes a heavy trigger... bust most often its the user that isnt up to par. My advice, if the stock is crappy get a good solid stock, bed the action, make sure the barrel is free floated and put a brake on the end of the barrel to make life more comfortable.

IMO the only way to get a SAUM to hammer in comparison to a 7mm mag is to hand load and put in the time developing a sweet round. Berger 180 VLD is the best place to start, or Sierras new 7mm high BC offerings.

Make sure it isn't the Indian and not the arrow. I also think that you could have something by putting some time, effort, and a little money into that 7mmRM. You may end up with something to fit the bill for a fraction of the cost and without the hassle of a new chambering.

Re: 7mm RSAUM vs 7mm WSM? I need help!!

Well I cant say im not flenching from the kick of the 7 mag pencil barrel. I did have it pillar bedded and floated. The stock trigger has been worked to around 1-1.5lbs. Im going to keep the mag for deer hunting, Iv just always wanted to build a custom but never had the money. Now Im going on a deployment to afghan and will have the cash i need to build a rifle I can be 100% confident in. The custom will probably never take the life of anything fuzzy, its just going to be a target rifle. I may get into F-class after i get out of the corps but not for sure yet.....

Any of the short action magnums are a BEAR to make feed WITHOUT issues. The only guys that have fixed this problem is McMillan with their short mag G30 action. They had to make it 25% wider to get it to work right. Good luck with your build! I know you CAN get that action from McMillan.

Tell that to APA, GAP, or any of the builders on the hide that have built WSM's on a short action.

My factory stock Remington 700 SPS Stainless in 270 WSM fed great.

I moved the barreled action to a McMillan HTG with Badger M5 bottom-metal with Accurate Mag 3rd magazines. One of the magazines works flawlessly. The other doesn't.

You say your factory 7mm REM 700 doesn't. Shoot well. Please provide a bit more detail like...

100 yard grips
factory ammo/handloads
etc..

I would get that 7mm Rem shooting well prior to diving into a full blown custom build. You could even modify the thing & get some outstanding results. Building a custom is a blast except for the wait!

7 Rem Mag...7 SAUM...7 WSM...

There is no significant difference between them from a ballistic standpoint, they will all provide nearly identical performance.

In other words, your 7 Rem, if tuned up would do whatever the others will, it actually may have the slight edge, but all of them need to be handloaded to mine their full potential.

Re: 7mm RSAUM vs 7mm WSM? I need help!!

1 moa groups at 100 with 162gr SSTs, RL 25 handloads (for deer hunting). Im not building a custom because i dont like my 7 mag. Im just way more interested in building a custom than dropping money into a hunting rifle that does its job just fine. I will have plenty of time in afghan for everything to be waiting for me when I get home. It just gives me somethin to look fwd too and to keep me occupied wile im there (im not there yet, leaving in April).

Re: 7mm RSAUM vs 7mm WSM? I need help!!

If you've already got a 7mmRM why not go a different route. I'd bed the 7mmRM and make it an accurate hunting rifle. Shoot it some at range to get really proficient with it.

Now if you plan to shoot in F-class with any 7mm you're using a gun that puts you in the open group, if you don't want a 308 (and shoot in TR) I'd go with a 300 WM. You can shoot it to 1200 or maybe more, it is a viable hunting round for anything in North America with the possible exception of the biggest bears, and cheaper to shoot than a 338 Lapua and the ballistics shooting a 220SMK are comparable.

If you don't have a 308 I'd get one of those, they are arguably a lot more fun to shoot (recoil on any of the magnums gets un-fun after a while) and the barrel lasts about 10 times longer, literally. A 308 is a great round for shooting almost anything mulie size or smaller.

If you want to punch paper with any 7mm you will be looking for new barrels about every 1000 to 1200 rounds. With out even a lot of range time that's a new barrel every yr, not to mention that they are going to need about 40-50% more powder for reloading.

I've got two 308s and a 7mmRM for bolt guns in the safe. The next center fire bolt action I buy will probably be a 300 WM, though I'm going to bed and accurise the 7mmRM, (probably going to keep it in the wood stock) and get a good 22lr trainer first, not necessarily in that order.

Most of its been said, little better case design w/ the Remmy; better w/ long bullets. A little more womp with the WSM. Performance in the SAUM is identical to .280 Improved and the WSM is the same as the 7Rem. Mag. I'd actually prefer the 7Mag over both the shortys.

Re: 7mm RSAUM vs 7mm WSM?

I can tell you two things from my experience.
I shoot handloaded .300 RSAUM with 190 gr SMK's out of a AR-10(TU). I also have a Remington Model 700 Ti and Remington Model Seven in the same chambering. Great cartridge! The Armalite shoots about .400" and has given me some impressive long range 800+ yd groups for a gas gun. The Rem Ti 700 is my hunting rig and shoots well with handloaded 180 gr Win / Nos combined Tech, under .600".
So I am impressed with the .300 RSAUM cartridge.
I am currently reloading for a Surgeon Scalpel in 7mm WSM. This is where I am having a delay. The options for <span style="font-style: italic">good </span>quality WSM brass in 7mm just is not available commercially. I purchased Winchester brass and was not impressed with consistency. I use Remington brass for the Armalite, and find Remington brass is more consistent than Winchester brass. The AR-10(TU) really beats up brass on ejection!
I purchased x300, .300 WSM Norma brass and am in the process of necking them down to 7 mm. I have never fireformed necked-down brass before and did not consider the time consumption to make <span style="font-style: italic">quality</span> brass, and barrel wear on a premium chambered barrel when switching to the 7 WSM cartridge PLUS the expense (powder, bullets, primers. I don't like the idea of burning up the first 25% of my barrel life just fireforming brass.
Currently I am in the process of trying to find a "Mule" (?) rifle to get the brass fireformed to the point I can even begin to seriously reload. I am looking at a used Savage in 7 WSM for about $350. I am looking at Savage for the ease of adjusting the headspace with the barrel lock nut to prevent case stretching while fire forming. Considering a <span style="font-style: italic">used</span> Savage is less than my Surgeon chambered Kreiger (by half), I would rather burn up the Savage barrel just to create the pressure needed to fireform the brass. I am on a sharp learning curve here so please no flamers!
I keep hearing Norma and/or Nosler is coming out with 7mm RSAUM brass, but no rumblings about the 7mm WSM brass.
With the popularity of he 7mm short mags rising, using <span style="font-style: italic">new</span> high B.C. VLD bullets, I really don't know what Norma, Lapua, or Nosler are waiting for when it comes to making 7mm short mag brass.

Re: 7mm RSAUM vs 7mm WSM? I need help!!

Feeding issues for WSM's WERE real for a while, first couple of years of rifles being rushed to market. I had a SAKO from the early days though, and NO issues with feeding. Now feeding has been addressed and handled. I won't profess detailed ballistic knowledge by any means, but I don't think there is enough difference to say the SAUM is more efficient, the WSM does have a bit more ooomph.

Despite Nosler offering brass for a couple of the SAUM cartridges now, I consider the SAUM line of cartridges to be dead, and tantamount to a wildcat. That may not be a factor to you. Dies may be available for the SAUMS, but WSM dies are definitely available.

I'd do the WSM--pretty simple IMO.

Re: 7mm RSAUM vs 7mm WSM? I need help!!

the only dies i cant find for the SAUM are the Wilson arbor dies. every other brand has dies like any other round.

I myself just dont like the short neck on the 7mm WSM. and if you use the 300 WSM brass, you then need custom dies.

Each to his own though, Im going to give the 7mm SAUM a go and see what happens. all i need is an action and stock.
