Hi Byron,
I've been lurking for a couple of weeks but your post and that of others concerning light springs on singlestacks really intrigued me. Its something I really want to experiment with. I currently have a 16.5 Wollf variable recoil spring and a Wilson (made by wolff?) 19lb mainspring. My question is, how far are the brass being tossed by the lighter springs? I currently have a hard time finding my brass as it is. The lighter springs might even make it worse. Thanks!
