I bought a S&W Governor a few years back and have played with it quite a bit. I've shot most of the 2 1/2" defensive and shot loads through it and have been less than impressed. The Winchester PDX1 load might be OK at near point blank range for defense but ignition problems with it keep it from being used for anything other than the range. I haven't been able to find the Winchester 000 2 1/2" load but I’ve heard other people give it positive reviews. The data I did find for it listed it's velocity at 1300 fps. At 500+ fps faster than the PDX1 load, I doubt that was from a 2 7/8" barrel.
The PDX1 load prints the three .40 caliber, 71 gr disc into 3" at seven yards and the 12 8.5 gr .180 cal. BBs are already spreading outside the silhouette. 15' is as far as you can go to keep everything in and 10' to keep them all in the chest. The one 10% ballistic gel test I found for it said the BBs penetrated 4.5" and the disc penetrated 7.5 to 8.5s". The load is listed on Winchester's data sheet at 750 fps. The combined disc/shot weight is approximately 315 gr and it produces a paper energy of 392 ft/lbs of energy. I tried chronographing it and the few readings I actually captured, and were in a believable range, were closer to 700 fps from the Governor. That would be 342 ft/lbs of energy. Also, I’m not sure that ft/lbs measurements are valid for a multiple projectile round. The individual 71 gr disc would be 82 and 77 ft/lbs. A 71gr. 32acp round is about 200fps faster and produces around 130 ft/lbs of energy. I've seen videos of slingshots that were more powerful than the individual disc. This brings me to my question.
Are 410 revolvers viable self defense guns? Once the shot spreads, can the individual pellets/disc be an effective fight stopper? I've studied terminal/wound ballistics of handgun ammo since I started my LE career 40+ years ago. Long enough to see the big/slow - small/fast debate roll around twice. I've read everything from 1904's Thompson-LeGarde test though the FBI test and beyond and hundreds of magazine articles on the subject. I haven't found any in-depth test/article on 410 handguns. Does anyone know of articles, test or research that has been done on it? Or, know of any incident in which it was actually used for self defense? Sorry for the length and thanks in advance.
