Wildrose,
I agree that ammo generally is more available (online) for the 7 STW, Midwayusa has 12 loads listed that they catalog, but only 3 are available right now. To add to the problem is the cost ranging from $49.99 for HSM to the other end being Nosler custom listed at $80.99 per 20. This pricing seems excessive and would certainly exclude many people from being able to shoot one like we like to. In the gun shops
up here in Idaho, you cant find STW ammo at all locally, so you must hand load.
I got my 7 STW when components, especially brass) was more available. I got lucky and was able to get 350 brass. I'm reserving 100 for later use. Now it seems almost impossible to get less-expensive (R-P) brass now, and if you want any brass the cost is incredible. For this reason I'm seeing used Ultra Mags as well, on the market.
I fortunately have other rifles who's components are more plentiful, so I shoot them a bit more and use the STW for long range use, since that was my primary goal.
I agree that those who've dumped their STWs are dumb, It's an amazing cartridge. It's long range capability with the Heavy for caliber bullets is incredible. That's why I couldn't possibly part with mine.
