7 mm stw

Yes you can run around 3300fps with 160gr bullets with a 24" barrel, just like you can run around 3400fps with 160gr bullets with a 26" barrel, but unless you are running coated bullets with a lot of freebore, you are probably developing well over 65,000psi in both cases.
 
Sounds about right.

I've found the STW to be easy to load for, with its congeniality leaving when the throat did. That's sort
of taken me down the 7-300 Win and 28 Nosler road, both housed in 3.700" mags. At least I can chase the lands for
awhile, and tag them with VLDs and such.

While I can't speak for anyone else I can say that the load I'm using that's pushing the TSX at 3275fps out of a 24in barrel is right out of the Barnes manual.
My experience has been that there's often more variation in velocity from one barrel to the next than will be lost or gained by an inch or two of length on the same barrel.

I find the loads in the new Barnes manual o be too hot for my rifle. If I run the max load in the new Barnes manual for the 140gr TTSX, I get 3600fps, but primer pockets are loose after a few firings. That tells me, that I the load is producing excessive pressure, so I backed off 2 grains and 100fps.
 
The year after Layne Simpson wrote that article in Shooting Times Magazine I found a used one built by North American shooting Systems I think out of vancouver on a sako Hunter with a 26" tube for around $650 and at that time I had to make my own ammo. I used .300 h&H brass which was cheap (because I am a cheap bast---d). Fire form and away we go. it was my hunting rifle for deer and moose for about 15 years. low recoil compared to the .30 cal magnums and will do anything they will. I traded it 5 years ago with some other rifles for a truck which I also love. I have recently acquired another STW built on a Rem. 700 action which I got on trade. I lent it to a friend to play with and he told me that on shot number two he hit a rock at 1100 meters so I think it has potential. The guy I got it from on trade did not know much about it but my friend recognized the barrel and is pretty sure that it was built by Corlanes in B.C. It has a 28" stainless barrel and is for sale. If any of you are interested in it send me a post. I have a Sako TRG in .30-378 that is my carry gun now during hunting season and it shoots so good with hand loads that I just can't believe it.
 
I have a Remington 700 "Sendero" in 7mm STW. Gentleman that I got it from didn't like the integrated muzzle break so he got it cut off and re-crowned the barrel. Barrel sits at 24". I was a little short on bullets so I only was able to shoot 3 shot strings. Groups were average except for one. Grouping at 100yds was 0.23" using Speer 145gr Match bullets. Chronograph was set 6' from the bench. Avg vel for the string was 3154fps. Interesting note in the latest Speer manual concerning the 7mm STW. It states that due to several factors; of which all affect the 7mm STW, bullets will not stabilize properly until distances reach 200yds+. So if you have decent 100yd groups anything past 200yds+ should be very good.
I'd like to build a 7mm STW on a Mauser action with a stainless 26" barrel at some point.

I've not had any loose primer pockets but this is good to keep in mind about the Barnes manual. Thanks for the heads up.
 
The STW has two advantages over a 7 Mag...it gets rid of powder at a faster rate so you can buy fresh stuff more often but the big advantage it has is that it will hit a target .0000001 of a second quicker...otherwise same-same.
