Anon,
If you want to come you are more than welcome. The pin league runs in the summer and the indoor rimfire target league runs in the winter. There are a few phone numbers on the website that you can call for more info. or you can email them at their ' contact us ' email address. In the past they ran them on wed nights but have switched to thurdays and I work on thursday night so I haven't gone in a while...
They are great guys and gals at out club and more than helpful.
I think they just use a sawzall to cut the tops off, I'm not sure how they keep them square when they cut.
Pins are fun and frustrating. Enjoy!!!
safety note: DO not shoot full pins with a .22. There is a good chance you'll catch fragments as they tend to bounce off. Not that I am speaking from personal experience or anything....
