OOC - SR3 Custom Firearm Creation Rules

I created these custom firearm rules for use with my games. I decided to share them, as I had a computer accident and lost the original files. Luckily, I had printed them out. So, I was able to scan them. I believe I took some ideas from someone else's custom rules and adapted them for mine. It was so long ago and I can't remember who that was, but thanks! There are some minor typos I discovered that I will remove when I get the time. You should be able to figure it out though.
All new firearms I post on my site will be made with these rules.
