Hey mate, thanks for reading. I did this one for you actually. It's a cool competition and yes, so much work, but it's cool, I gotta give back sometime. I actually just backed it up with a little post answering a question about cartridge size. You might want to take a look sometime. It's not technical of course, just basic.

Joining a range is a great way to get involved, meet new people and expand the mind. I can't wait until ours reopen.
