I was interested in mule ear locks, but couldn't find one to buy. When L&R introduced one a few years ago, I jumped on it without even knowing what I would build around it. I thought its shape lent itself to a Bedford style longrifle. I picked up a precarved Bedford stock from Tiger Hunt at Dixon's fair along with a 13/16 Rice barrel in .45. The advantage of the mule ear lock is the short, straight channel to the powder. It shoots almost as quick as a centerfire rifle. I've done well with it at NMLRA territorial matches.
