Would you please share your experiance reloading the 7mm stw. I would like to reload 140 grain Siera game king, I also have Winchester brass(new) and also Federal No. 215 primers. What powder would you use? I have been reloading for several decades, but my manuals are a bit dated and the stw is not listed. i will be getting a new one soon. Does a person dare put the bullet on the lands?!
