I don't hunt but I have a 700 Rem target rifle in 7mm STW with a 29" Hart barrel set up specificially for 1 mile silhouette. 180 grain Bergers are excellent. Any cartridge at that range is asking to wound animals as they can walk out of the trajectory after you fire, or a mid range breeze can move the bullet by feet.

Comparing it to other 7mm magnums:
cartridge case_cap SAAMI_Max case_len
7mm Rem Mag 82 grains 62366 psi 2.500"
7mm Wby Mag 87 grain 63817 psi 2.549"
7mm STW 97 grain 66717 psi 2.85"
7mm Rem Ultra 112 grain 63817 psi 2.85"

I also have a"factory" 7mm Rem Mag Win 70 Laredo with a 26" barrel and its accuracy at 1000 yards is comparable to the 7mm STW (at 1000 yards) with considerably ligher recoil.

It seem to me you need to conisder the maximum range you'd consider shooting (at) a deer or elk. I consider myself a pretty good shot but I know I could not >reliably< make clean kills at 1000 yards. I've shot 6" five shot groups at 1000 yards, but I've also been off by more than a yard with first shots in changing donditons. It doesn't seem to me that traking a wounded elk with a 1000 yard head start would be easy.

I don't seem to recall reading anywhere in garyb's post about 1000 yards, much less a mile. Those are YOUR words, not his. He may well consider 400 yards "long range". Don't jump to conclusions!!

tod...dont jump on your own tougne.....


this is the 600 yd/1000yd BENCHREST forum


so it is correct to discuss the two distances listed for this forum....

much simpler if he had posted on a hunting or general forum....

So my last thread (tonight) on the 300 win is all about 1000 yard shooting??? NOT HARDLY. Don't get me wrong, my next 1K match BBL might just be a 300 win mag, and I figured some of the guys here shoot one. This is the best place for advice that I have ever seen!!! But...as you say ....this IS the 600/1000 yard sight, right. So......Is 600 yards "long range"????? Maybe 600 is long range for him, but he shure-n-l never said a word about 1000 yards or 1 mile. And I don't recall gary asking for a lesson on ethics......I guess that is your domain, along with Mr Boyd.

Did you notice that g n brezinski chose to start this thread in the 600/1000 yard benchrest section, and that the the 28" heavy varmint contour at least suggests shooting from a rest. The 7mm Rem Mag has sufficient energy and accuracy with appropriate skill and bullet selection for killing an elk reliably at 400 and maybe to 600 yards, but gnb is asking about the 7mm Weatherby and the 7mm STW. I was attempting not to get into the ethics of extreme range hunting. I only suggested that gnb consider the range at which he wants to hunt before selecting the cartrige.

no,,
but the owner of this site is a BENCHREST shooter. this is his site and it is set up to support BENCHREST shooting. to help others, who have questions that are not BENCHREST related, or have non-BENCHREST related questions(like HUNTING), he set up a seperate forum...FACTORY/HYBRID rifles. this would be the appropriate forum for both of these postings. you will get few replies here, as most benchrest shooters have taken the stand to just ignore poorly placed posts.

Go with the cartridge that will shoot a Barnes 160 grain triple-shock at a solid 3300 fps.

This combo will get the job done that you have in mind.

You will not need a barrel longer than 26 inches.

Picking the correct powder will be the trick.

Everything is a compromise.

7mm Rem Mag fun to shoot
7 STW has enough horsepower to do anything a 7MM should be used for.
7mm RUM for those that like having the biggest baddest rifle around. Short barrel life.
How about a 7/338 Lapua, I've got a reamer for that. Got a 7/388 lapua Imp also.
Just depends on how crazy you want to get. Nothing free, you pay for velocity.

It's fallen out of favor but I've never built an STW that I or my customers didn't really like.

My advice is to chamber the barrel for 7mm Rem Mag or 7mm RSAUM and practice shooting at long range. I really enjoy shooting the Rem Mag but the STW without a brake is abusive. In readable conditions I would be comfortable shooting deer with either the Rem Mag or RSAUM out to 1000yards or so. For Elk I would limit my shots to 300 to 400 yards unless you want to move up to someting like a 338 RUM 338 Lapua or 338-378Wby.

Just my opinion

IMHO I would look at the 7mm Dakota (NO BELT) 7mm WSM or a 7mm based on the new Ruger cases 7/375 for the high end or 7/300 more sensible;) I have 7stw sendero and a Win super grade 7stw good guns but I hate the belts:(

You need to define what you long range ideas are.

There ins't much the standard 7rm can't do to 1K. Like wise the 300wm.

If you are dead set on 7mm, start with a 7mm WSM. The 7mm REM ULTRA MAG may be more fun than you care to experience with a rifle light enough to drag to the killing fields. I own both, and I will probably never shoot the ultra enough to work up an accurate load! When I torch it off, it belches, bellars, jumps up about 18", does a "marlin twist" and comes back down about 2" off the side of the cradle of the front rest, gorping the stock. The Dakota has a little larger rim, necessitating opening up the bolt face or reducing the rim diameter. For deer or elk, I really like my .300 WEATH., 308 NORMA, But I really prefer my bow. STEVE.

Any 7mm that was properly built with good components, sports good glass, is Pillar Bedded and nestled in a quality LR stock and all is resting on the proper rest will do as long as you are shooting a .600+ BC bullet at 2,950+fps. LR to me is 600+ with 600 being the short portion of the range. Here's mine, a 7-300wsm I built. 180 VLD Bergers at 2,907fps

There isn't much the 7wizzum nor the 300wizzum can't do as well.

... simple cartridge that is easy to load for. I use 300 Win Mags, 300 WSM, and 7mm Rem Mags. All very easy to tune. And the best dies are available for easy purchase.

From experience, stay away from the 7 WSM. It will eat a barrel in less than 500 rounds. It took me two barrels to understand what was happening. After all of the success that we had seen with the 300 WSM, I was very disappointed with the 7 WSM.

The 300 Win Mags give me more than 2200 rounds, and the 7mm Rem Mags give about 1200 rounds. I am now just changing the first 300 WSM barrel, as it gave me 4500+ rounds and was still competitive.

For those who think otherwise on the 7mm WSM, I have a reamer for sale, used only twice.

I have over 1200 rounds on my 7mm saum and I think it's still shooting ok, I pulled a 49-1 and a 49-2 out of my a$$ at the NBRSA 1K Nationals. The last LG targets it shot before the Nationals were a 50-1, then a 46 in the shootoff.

James,

I will admit that I have no experience with the 7mm SAUM. It may be the ticket for 7mm. I would be curious as to what powder and bullet combination you are using. And how many barrel have you had chambered for that cartridge?

The spec of the reamer are minimum sammi specs, .308 neck, and I believe what my gunsmith calls a live pilot. Made by Mr. Kiff.

Danny,
I am shooting 162 A-Max bullets and 66.8gr H1000 w/ BR 2 primers at 3127fps, the barrel is Bartlien 5r 9 twist. I have one other barrel chambered in with the same reamer, it's a Lawton 6 groove 9 twist. I think I have around 200 rounds on the second barrel, although it is also a LG (15 1/4 lbs)I shot it in the HG class at the Nationals. It gets 162 A-Max and 58.4 gr of H4831sc w/ 250 primers at 3015fps. The reamer is made specifically for necked down Nosler 300 saum brass and has a slightly shorter neck than a factory 7mm saum(2.015, I trim to 2.000). It is a no turn neck, .318 chamber and .316 loaded round dia.
My reamer is a floating pilot and also ground by PTG.
Before the Nationals I inspected the throat with a cheap bore scope that I had trouble focusing but the throat looked too good for the round count, I need to look at with a Hawkeye.

Chris Matthews has 600+ rounds on a 7 wizzum light gun. He just shot at MO State Championships and posted 2, 3" groups.

Danny Brooks

I tried to use the slowest powders like H1000 and Retumbo in the 7mm WSM so that I wouldn't burn the second barrel out.

The first barrel had about 600 rounds through it when I went to a 600 yard match in Bridgeville, in Dec 2005. I ask the shooter next to me to watch where my first shot went, as I was coming up from a 200 yard zero. The shot went through the target at 3 o'clock in the 9 ring, but I watched the vapor trail as it went to the target and ask the guy next to me if he saw how fast it got to the target. He said yes and agreed with me that it was definately faster than 2950 fps. I chronographed it the following weekend and recorded almost 3200 fps. Then went to Clay Spencer's the next weekend to bore scope the barrel as I couls not find the lands with seating the bullet. The throat was burnt out over eight inches.
I assumed that it was just a soft barrel and told Clay to put one of his barrels on it.
I got the gun back two months later, worked up a load and shot it with some success throughout the Spring of 2006. When getting ready for the World Open in Pa., I checked my seating depth and had one thread left in the seating die to seat the bullet kissing the lands. The barrel had just over 450 rounds. It shot competitively, but I could not bring myself to shoot a caliber that would have to be set back every 400 rounds.
I took the gun back to Clay and when he asked what was wrong, I told him that it needed a larger hole down the center.
I spoke with others at the Pa. club who shot the same and they said they would set theirs back as they liked the way it shot. More power to them. I don't spend my money that freely and I don't have my own lathe.

In conclusion about the 7mm WSM, I believe that it is overbore. To get the bullet speed up to 2900 fps with a 9 twist, I don't believe there is a powder that will not burn the barrel out.
Maybe the 7mm SAUM case will do that, but I am going to let others play that game and stick to the 7mm Rem Mag.

On another note, the gun now has a 300 WSM barrel on it & seems to be doing quite well as the stats will show from the IBS nat'ls this year:D
It surprised me more than anyone.

Ric,

I would like to know, what powder and bullet combination Chris is shooting in his 7 WSM. And what the bore looks like in a couple hunderd more rounds, just for the sake of knowledge.

I think he shoots H1000 and either Bergers or Cartarucio (sp ) I never get that name right...
if'in ya go to his website his e-mail addy is there.

I would still like to know what the bore looks like after another 200 rounds. If it is in fair shape, I might build one to try as an experiment. The only draw back is the quality of the brass, as I have never found a lot of Remington brass that was all that great.

If I had to use Remington brass for my 7 SAUM I would probably find another case.
The 300 SAUM Nosler brass is however every bit as good as, if not better than my 6BR Lapua brass and superior to 300 SAUM Norma brass.
