Well,Remington introduced the 7STW,but also soon did a good job of trying to kill it when they introduced their line of Ultra Mags.Still a great round,I have one in a Sendero rifle.The published load data is well below what it's capable of.Oh,and very accurate too.I have some Winchester 150gr factory rounds that run 3450fps.I was able to duplicate this round.I pulled a bullet from one,weighed the powder,did a little research and found it was loaded with 80.0grs of Winchester WXR powder.Other research on this,I found that this powder(now discontinued) was made in the same factory that produced Norma MRP powder.The WXR and Reloader-22 powders were lots that didn't quite meet the specs as Norma MRP.I've compared the WXR and Reloader-22 powders.My rifles group them the same and the velocities are usually around 15fps or so difference.I don't shoot mine too much anymore because brass is hard to come by these days.The load I'm shooting is 77.0grs of WXR with a 160gr Nosler Accubond running 3200fps.

As Bob Hagel would say"You should not use a rifle that will kill an animal when everything goes right; you should use one that will do the job when everything goes wrong."Good words of wisdom...............

My #1 elk rifle is a Rem 700 with a take-off SS fluted 7 rem mag barrel that the orig owner punched to 7stw. 79gr of h1000 with Hornady 154 Interbonds gives 3250fps.

Remington loves to eat its' young.
They killed the 280 with the 7 Rem Mag. Im sure the 7mm RUM did the STW no good.
I guess the 7mm Weatherby got in the way of the STW about like the 300 Weatherby got in the way of the 300 Win Mag,.......which is to say not at all...or very little. The cartridge is fine but not everyone loved Weatherby rifles and freebore.
Rifle buyers are fickle,always looking for something new. The STW has just faded into obscurity. It wasn't even new when it came out....had been around for years in wildcat form.

The 280 Remington is overbore.
The 7 Rem Mag is over bore.

IIRC it was Shooting Times editions with Simpsons stories on the 7 STW that had me drooling on the pages reading the numbers.

Yes, the lawyers gelded it, but I did reach Simpsons numbers with RL-22 and 7828 with 140 gr ballistic tips, 3600 fps with first gens was a fuggin bomb!  I remember reading those numbers with my old merge together range finder in my lap, I was so giddy bout went out and bought a fresh lard bucket.  ;]
