Buckshot effectiveness at 50 yard range.
John Ervin at Brass Fetcher Ballistic Testing is a friend, and I have a lot of respect for his research. We talked about this project a while back, figuring out how to get reliable data, and it’s cool to see the results.
The whole vid is worth watching, but if you’re looking for just the results, skip to about 7:00. For his conclusions based on the results (with some excellent advice), skip to about 9:30.
Bottom line: use at least 00 buckshot, if you want it to be effective out to 50 yards. Know your gun, and test it to see what loads perform best at that distance.
