Thinking about doing a 7 STW build on a Savage 110 300wm that hardly sees much use recently...thinking a Carbon Six barrel at 27 inches.

Whats a good length for the 7 STW?
 
Is the magazine long enough to take a 3.6" STW?

Thanks....just measured and NO its only 3.52....well shyt, scrap that idea :(

Looks like I'll have to do the 7 STW build from my rem 700 8mm Rem mag thats been collecting dust for the last 15 years or so.
 
I have made a few 28 inch 7mm STW's. If you want the most in velocity and can live with a long barrel - it works well. I would not go shorter than 27.
 
26 in is working fine made off a 700 rem if you are trying to Max the speed out of an overbore cartridge the barrel just burns out
faster for what you achieve:)

Any reason you don't just go 28 Nosler and call it a day?
 
While most facctory rifles and many custom rifles in 7MM STW are 26" long, some people prefer to go a bit longer.
My 7MM STW was built by the original owner on a lh Sako AV action and MacLellan stainless fluted barrel at 24". In a Fajen laminated stock. Bare rifle weighs exactly 7 lbs. I find it very handy when hunting in the brush and mountains. The mag box is long enough (donot know if stock or aftermarket, and the action has a small cutout on front edge of ejection port for trouble free case ejection.
My barrel is a bit faster than some others, as the Federal Premium factory ammo with 160 gr AccuBonds are shooting at a chronied 3222 fps, as opposed to the factory listed spec at 3100 fps. It will also put 3 into an honest 1" at 300 yards, when I do my part. It shoots so well with the now discontinued factory ammo that I have not felt the need to handload for it, yet. Still have a good supply of the factory ammo left. Including the Federal Premium 160 gr SGK load.It will put 3 shots into 3" @ 400 yards. Do have all the components to handload down the road.
Have taken alot of game with it over the past 20 years from antelope to elk, and at 15 to 475 yrads, and have been very happy with its performance. Nice to know that the160 gr AccuBond is still packing over 2000 ft-lbs of energy at 500 yards; plenty for any elk!
Big fan of the 280 Rem and 7mm Rem Mag as well. I was actually very happy with my 7mm Rem Mag and would have not gone to the STW, except that I sold the rh Rem 700 in 7 Mag, to get a lh rifle, when I came across this used lh Sako STW, and could not pass it up atthe price it was for sale at.

I'd imagine a 3.52" OAL would work with a lot of bullets. The 28 Nosler is a more practical route in 2019 and will work better in the 3.5" mag box

26 inch is a good barrel length for 160gr or less bullets, if loading 175gr+ I would go 24"
 
Well looks like if I'm to build on the savage then 28 Nosler is the way to go as I'd only have to change the bolt head.

Thx again to todbartel for pointing out the mag. length.

Why would you have to change the bolt head if its already a .300 Win? The 7-300 Win is also worth a look as a magazine friendly option, that neatly side-steps brass availability and price concerns.



On the barrel length; 26" is the easy answer but I've had 24" STWs as well. Usually that was due to rechamber jobs (One was Cooper screwing up); they may not have been all they could be but they were a heck of a lot faster than a 7 Rem so there's that.


I've got a 28" STW that produces the same speed or less as my 26" 7-300 with the same 180 VLDs. These things happen when you're flirting with cases that are all trying to shove about all the powder down a .284 hole as can be reasonably done.

As an aside, my 28 Nosler sends 196 EOLs out of a 29" barrel at 3080 fps.They friggin smoke things.

What is the COAL of your 28 Nosler loaded with the 195 Bergers? Yes you are right the 28 nosler base will fit the same bolt head :)

That's why I suggested it originally. I was recently looking at building a 7stw myself and although I'd still like one in the stable it doesn't make any sense to pick it over 28 Nosler.

Yes, I'd have to agree with what youre saying after giving it some thought. :)
 
Well the more I research into this project the more difficult it seems. Although the 110 I have now is a small shank savage and chambered in 300WM I've been told by a barrel maker that I require a large shank savage if I want to go the Nosler family of cartridge or any of the WSM's,RUM's, etc....they don't recommend any of the fat cartridges for a small shank.
So looks like the STW is too long for my mag. length and the Nosler etc are to large for the small shank...oh well, better to learn this now than later!
