The 7mm STW has been around since '79...I think if you're a reloading tinkier cartridges like the Sherman are wonderful. I think the average reloader will quickly tire are dealing with all the steps needed . My father and I are prolific loaders but back in the 90s the only readily available hot 7s were the 7 Rem Mag and the 7 Weatherby, then the 7 STW showed up. So, we built a couple of STWs. Well there was no brass so we had to make brass from 300 Weatherby cases by fireforming . There was no 8mm Rem brass available to neck down. Needless to say it was great fun for the first year but quickly became a pain in ---. It was a huge relief when Rem started making factory brass. I actually got a lot more service from the title then. It soured me on reloading for awhile.
On the 7 WSM I'm not sure where you can get ammo or brass. A friend built one and he had a heck of a time finding brass and at the time the factory ammo had dried up. If you want a WSM I'd build a 300. Our of the 3 WSMs it's the most efficient and can handle the largest range of bullets . I've owned one, my son and father both still own one. I reloaded for mine for 10 years and still reload for my son's. We've shot hundreds of rounds in them and killed Coues deer, mule deer, elk, antelope and African Plains game . I think if you study the ballistics you'll find the 300 using 150gr to 200gr bullets is very efficient and there are tons of bullets. All three of our 300s love the Berger 190 VLD for longer range reach . For tougher targets like Plains Game the 180 Barnes TTSX or Hornady GMX also shot very good. There is a reason the 300 was really the only commercial survivor of the 3. I had a 270 WSM but the lack of high BC bullets makes it fairly limited in the long range department .
Anyway, good luck with your choice I hope it's a pack driver. I'm working on loads for my new 6.5 PRC.
