I have the smaller framed "Public Defender" model which I carry in a custom made pancake holster when I am relic hunting. First round up is a 2 1/2 inch load of 71/2 (poisonous snakes up to 10 feet away), 2nd. & 3rd. #4 shot (possible rabid skunk, fox, opossum, etc. up to 10 feet away), 4th & 5th - Hornady 000 Buckshot (possible rabid/aggressive animal dog/coyote size up to 15 feet away.
There has been several controlled test involving this revolver and different shot sizes & pattern results. The smaller shot, such as 71/2 tend to have a "doughnut" pattern with a hole in the middle. The larger shot sizes, such as #4 patterns quite well up to roughly 15 - 20 feet away. As far as the buckshot loads, they tend to hold a fairly tight pattern up to roughly 15 to 20 feet away.
The only time which I would tend to use the buckshot load for self defense would be in a situation where the perpetrator is not armed with a firearm and is within 15 to 20 feet away and I could not get to either one of my laser sighted Ruger LCR's or P-90.
As far as the .45 Long Colt round goes, I really did not intend to use this round in my Judge. However, I well may do some accuracy test at a later date just to satisfy my curiosity. I feel as if it should be able to place most rounds in center mass of a silhouette target at say 15 to 20 yards. Maybe I'm right in my expectations, then maybe not. A range test will tell the truth from a sand bag rest.
Contrary to the beliefs and opinions of others, I feel that the Taurus Judge has its' place in certain situations, but should not be expected to be the "kill anything at any range revolver".
As we all know, it is not necessarily the size of what is sent down range, but the ability of the shooter to place the round in the proper location needed for a clean and immediate as possible kill. Just consider the number of people who have been killed with a well placed .22 caliber round.
