RE: Clean barrel sight-in
Hunting with a clean barrel is too much work IMO! I like shooting at the range without having to clean my barrel between each shot!
With 777, one spit patch followed by one clean patch (what I still call a fouled barrel) is how I like to practice and hunt.
With BH 209, I have shot as many as 30 shots WITHOUT SWABBING ONCE! That is a lot more fun for me than having to doa lot of swabbing, not to mention what it would take to really clean the barrel between each shot. And I get great groups with this method.
It is a lot less work to foul my barrel before I hunt than it is to practice by cleaing between each shot. AND the first shot will always go where the first one did in a quick follow up!
