Those are my own loads that I produce.
It is a pretty popular load. In fact one of the guys either here or at 24 hour Campfire cleaned me out last week, as he had a competition he was going to and he was running them through his Model 97 Freedom Arms. I have since then done another batch. A few guys over on the Campfire use them for their deer hunting loads as well.
One of those "just right" kind of loads.
Pretty sure the flier was me. I have a gift for flinging one shot out of a good group.
