I've loaded the Speer casules with #8 and #9 for .44 and 38/357 for years. They work great at close range, especially 10' or less. I used to load a couple hundred at a time for friend who took them to Texas for snake hunting. We both were shooting the 38/357 ones from 6" Rugers. The maller the shot, the more pellets you get. #9 worked better than #8. I never bothered loading anything bigger. Also, they patter better at lower velocities so don't overload. Never heard of the blue caps coming apart or sticking. Never experienced any problems with with the ones I loaded, maybe 1000 total in both calibers.
Not much defense value with their limited range, though I suppose the bigger capsules with a 1/4 oz of shot might be good anti-carjacking load, but I'd rather have a single slug.
