Thanks John. I printed one batch from the PDF file and they didn't line up correctly. I created Word documents from them and they came out great! I might see if I still know how to use Photoshop and clean up the front pictures to make them look a little more professional. Maybe I'll put a 1911 on there instead of a Glock.
Edit: I saved myself some Photoshop work by using Google. has several different ones already made up with different guns. I was able to print directly from Acrobat to Avery 8371 with them and they have crisper images and text on them.
