Not a good idea
The Speer shot capsules can do a lot of damage to building exteriors without killing/hitting the bee with the shot column. I followed load data in a Speer manual for 38 spl capsules. At 8 feet a large crow would survive the shot pattern and the biggest hole was from the shot capsule. I would not shoot bees with shot capsules where I might hit glass, vinyl panels, aluminum facia, or the boss's plants.
Does Speer still make the loadable shotshells for .38 and .45?? You could fire a lot more volume cheaper with this rig. I haven't had much luck with pistol shot but I didn't have a 6" .45 that I think would be ideal.
