It doesnt look like this is an active forum but I thought I would post any way. I just got a new . 50 cal BG and I think I like this caliber better then my . 625 caliber. Its a lot easier to shoot and my chest and lungs don't hurt after 15 minutes of shooting. The other thing I like is that it's an even number size instead some odd ball size so it will be easier to find something to use for a cone. Time will tell.
