Home Forums Hunting & Shooting Long Range Hunting The Big 7's......Which One?

LOL... funny how a .260 put a pause to the discussion in this thread...

I'll add my vote for the 7mm Wby if I were to go for a "Big 7". It does what the 7mm STW does but in a shorter package. After that I would go with the 7mm WSM.

No it doesn't.

Well looking at the Nosler #6 manual it pretty much equals the STW with a 2" shorter barrel when shooting 150g or bigger.

Well.....things get scewed in real life...like in equal barrel lengths and at equal pressures, the STW is just a faster machine.....I am suspicious when smaller cases give the same velocities as bigger one's.....something ain't equal somewhere.

Anyone that has loaded for both must agree the STW has more velocity than its lesser sibling, whether or not it's significant is another question but it has more potential velocity. BTDT, make mine a STW...

I guess I could look up the operating pressures of both, but I have never heard of WBY downloading their cartridges, but we are talking reloading. Looking at several manuals the only time the STW really beats the WBY is with 140g pills and that only by about 100 fps. Hornady even has the WBY slightly ahead when both are using 26" barrels and heavier bullets. Other manuals (Speer and Barnes) show the STW only slightly ahead using 24" barrels. I would say they are pretty close to each other.

I recall reading the STW got its original speed by being in the 70,000 PSI area. A little hot I'd say.

Been'n we on long big 7 rant, anybody neck down the good ol' .50 cal to 7mm yet??

Start'n to think the 7mm cal. has been put in more different 'magnum' cases than its seemingly ailing competitors .30 cal and .277 cal....

Silly other calibers.....

Just in case anyone was wondering... ...I'm building another 7 Rem Mag. This will be my 3rd one, and since I know them so well, I'll stick with it. Using some different components, tho. Some that I haven't used in the past.

And when that's done, another 7MM-08. Gotta love 7MM...

Running the 180 gr VLD the STW will give me 3150fps and our custom throated 7MM Rem Mags will give 2975 fps.

File this in the �For what it is worth� file.

If running the VLDs I prefer the 7MM Rem Mag/custom throat route as the STW needs an extended mag box and always seem to die a little early.

Heck Yukonal, what did you do with the first two 7RM? What will you do different to this setup? Inquiring minds want to know...

Sold the Gritters custom. Still have the Tikka Laminated Stainless...it's a rare bird, and shoots 1/2 moa at 400.

I think on this one, I'm going Greybull on the stock. I have to handle one first...next week at SCI. Also, for me, a #5 is heavy, but that's the way I'm going. And adding a Vais brake. It'll be the first brake for me, too.

I want to come in at 10# scoped. I think I'll be pretty close.

What action?

The STW has about 10-12% more capacity than the 7mm Wby, end of story. If you can't get more velocity from the STW in the same length barrel you're doing something wrong...

This one's a 700 LA. The next two will both be on Tikka Actions.

Sounds like a fun project!

I think you are going after the wrong person. I quoted several reloading manuals. If you disagree with them let them feel you wrath.

Im thinking we have a new convert....

FWIW, I have a LH 7 WSM Savage Model 16. It has a 26 inch 1:9 tube from same. With the 180 VLDs, I get 3030 fps with 68 grains of Ramshot Magnum. Now I'm getting 2970 with 62.5 grains of Re 25. I actually have to throttle down this rifle. It has proven to be more accurate than I had hoped, too. One of my lessons has been that, if you want to push a 180 grains over 3000 fps in a hunting rifle, you need a scope with good eye relief ...

Only 6.4 Mils of come up needed at 1K yards.
