Looks great! Are they from kits or real cartridges. The reason I ask I've been asked to do one in a 30-06 but I'd rather do it in a real cartridge but not sure how. I'm sure he would like something like this!
Aalfred: I have not used any of these, (http://www.bulletpenkits.com/index.php?main_page=index&cPath=1_5 ) but they do give you a choice of calibers. May be worth a look see to you. Also, I have one 30-06 kit hanging on the peg that came from www.woodnwhimsies.com

If you want to know how it is done, let me know. I'll be glad to share information.
