Back when CCI factory shotshells were unobtanium, I was out of .38 shotshells and Keith (Ackleyman) responded to my WTB shot capsules to reload some. Keith was good enough to offer to fill 50 w/7 1/2 shot for me. Factory looked to me to be #9 or smaller. Have had the factory require follow up shots on some of our big rattlers, so I gave it a shot (pun intended) and was very pleasantly surprised at the results. Promised Keith I would let him know how they worked on snakes.
After a year or so, I had to report that they were the best darned snake protection I have ever carried because I haven't seen a rattlesnake to try them out on ever since! That's OK with me, too.
