Re: 7mm STW Brotherhood - For those who shoot the 7mm Shooting Times Westerner

My Sako 995 7stw is officially up for sale. I have 2 sets of Sako rings and a brand new Leupold VX3 4.5x14 CDS is mounted on it. The scope has 0 rounds under it. Will sell rifle alone or as a package with scope & rings. Any reasonable offer will be considered. PM me with any questions. - Bob

The STW fits between the rem mag and the ultra mag. Most feel it is just a few fps faster than the 7 Dakota of which it is, but it's not an ultra mag. So don't push it to that limit is my thoughts. If you need more stopping power it's off to a 300 Weatherby in my opinion. The 7 STW is the ticket in 7mm. But it's still limited by bullet manufacturers making bullets to perform at the over bore level. They are out there, keep looking, your 7 STW will find one.

2cents
Well put Ed, and I couldn't have said it any better. The 7mm STW is the " crem de LE crem" in the seven mil.world. That being said, as Ed put it, it still has it's limitations. It can be driven faster, if you dare to, but we are still depending on the bullet to do it's job at the terminal end. We all love the seven mag. The STW is just about as much "overbore" that can be managed and made to shoot. Yeah, the Rum is marginally faster, but with a more substantial price. WAY,WAY less barrel life, finicky as all hell, and very rough on brass. Most people I know that have one that shoots, have down loaded it to get it to shoot, and now they are getting STW velocities. Go figure.
All in all, I love my STW's. They are in there on class, in some ways, and they are a finesse round, that in the right hands, will last a lifetime. Layne did it right, and to him, he has my thanks. I was one of the early buyers, and the rest is history.Long live the STW.

I'm using a Sako 75 Stainless, 26" barrel with a muzzle brake.


I have a 24" rem 700 and I could not get the velocities I wanted with it and H1000. I was able to get the velocities you are seeking with the 162 gr sst and IMR 7828.[/QUOTE]

Big Jake Duke, one of two things are going on here, either your chrono is off,( which I think really isn't the case), or you are running skyrocket high pressures when using the H4350 and 168's. As one gentleman to another, you are closer to burst pressure than you could ever imagine. The STW will throttle along quite happily at about 62000-65000, and will give amazing accuracy and incredible knock down power, with about any bullet weight you may choose. However, and respectfully so also, you are at or approaching 76-77000 psi at the trigger pull. Fast YES, safe NO NO !
I would recommend trying some RL25, H1000, or something in that burn rate. My hat goes to the RL25. The STW responds well to high load density loads, such as in the 79-82 grain area. Leaving a large air space above the powder opens up a secondary explosion effect, and that is nearly as destructive as a double charge.
Please be advised that I say these things in all due respect to you loading ability, but in all truth, H4350 is not a suitable powder for the STW. Good luck, and be SAFE.

I'll second what 7 says,Those loads scare me from here and as 7STW said I mean no disrespect at all but the 4350 is way to fast and Im sure your way past pushing the limit,

I'm going to jump in here. It was me who was loading using 4350, not Big Jake Dude. He was quoting one of my posts and it didn't show up as a quote.
If someone is getting flogged for using 4350, I don't want it directed to the wrong guy.

I simply tried the loads, and got great velocity and accuracy. The average velocity over the chrony was 3320fps. None of the cases had any pressure signs at all, no flattened primers, bolt lift was one finger, nothing. I know the load probably isn't something I will stick with, but it did work well. If the pressures were in the 75000-77000 range would there not have been signs showing up?
I have several Sako's and have grow up shooting several other Sako's, they always seem to respond and shoot best when loaded hot. (usually over published max loads) They shoot these loads without pressure signs showing up. (yes, they can be loaded up to the point of pressure showing itself)

There are several loads listed using 4350 in the STW. Hornady's manual only lists it in use up to 120gr bullets. The reloading data on Hodgdon's site shows loads up to 150gr bullets, and pressures in the 53900 range, and on Loaddata.com there is loads using up to 175gr bullets and loads using160gr bullet loads in the 62000 pressure range.

I'm not trying to argue, I'm just curious as to why so many loads listed but so many people say that 4350 is too fast for the STW. I am always eager to learn more about reloading and shooting so input is welcome.

Edit: Also has anyone tried Hybrid 100V? I have it to, just haven't loaded any yet.

In a word no.
The stw will not show extreme pressure signs until it is in proof range. I had a guage on my last rem (a sendero) and it would easily do 75,000 psi without crying a bit. Low taper and rather sharp shoulder combined with a pretty strong case make it a rather tough hombre and able to take pressure without jammimg the gun. Read on though as I don't advise over-pressure.
Primers are all about headspace-- they aren't reliable for the most part as pressure indicators. greater headspace = flatter primers. If cratered or blown you know you'd better go to church and thank someone, otherwise they aren't of much use. Pockets will eventually loosen from stout loads, but even that is debatable since softer brass will often loosen some on the first firing.
The biggest problem is the actions will eventually stress fatigue(think airplane structural fatigue from compressing/de-compressing during flight) from overloads and either you will set your headspace back(ruined or shear the lugs and eat the bolt. I'd rather not have either happen.
