I've been loading some shotshells in Speer capsules for my handgun. I have #8 and 9 shot, but have read that people have used #12 with good effect at maybe 10 feet.
Does anyone have a couple of pounds of #11 or 12 shot they would be willing to part with?
There is one company that sells that size shot, but 10 pounds would last me into the next century. I don't expect to use much, because Rattlesnakes are a protected species in my home state, unless one is preparing to fang somebody!
Rats and other vermin will be the most likely targets.
Tree huggers, I can maybe understand, but Rattlesnake huggers?
