In my recent post titled "Heavy Lead in the .45 GM/TC Renegade" I mentioned using some commercial .50 caliber felt wads under the bullets, and that the wads were difficult to get into the bore.
Not only was it a tedious process, it was hard to get them in flat without cocking. The wads were Bridgers Best (which I think is the same as Ox-Yoke) and have a measured diameter of .508/.509.
I won't have that problem in the next range session.
The home-cut wads in the picture below have a diameter of .458/.459. compressing easily into the muzzle and filling the grooves perfectly. I figure I'll be getting 1,728 wads from that piece of felt.
