In the past I have put an extra round in the "pencil pocket" of my camo bibs. That works pretty good with larger rounds. When using my 7mm-08 I had to put a safety pin at the bottom of the pocket to keep the round from falling down in the pocket where I could not get to it. Now I have an ammo holder that goes over the butt of the gun, but the loops that hold the ammo are starting to stretch, and a round or two will occasionally fall out. I know someone that has the TC wrist holder, he likes it alot. I've been thinking about getting one of the TC wrist or forearm holders for myself, but I have yet to do so.
