Good shooting buddy. There are a few of us working with these right now also testing on a few vermin when we have time in 45, 44, 475, 500, and 510. I'm hoping to get to the 510s very soon, time just hasn't allowed for it yet. We plan to do a neat article on them when we have compiled what we think is enough good pictures and load data for the ones we are working with. I'm looking forward to it. Very neat bullets! Thanks for sharing your success!!
