Well, the Yellow Jackets are sizzling fast (they actually make a sizzling sound when you shoot them) and have a pointy bullet with a very deep hollow point. Combined this makes for a nice gopher round. Luckily this is what shoots best in my CZ.
I would like to try the Stingers. I've not seen them at the store in great quantities so I've never bought them.
I thought that the CCI Quick-Shok (fragmenting bullet) would be the end all for gophers. They shot great at the range but cause no extra damage on gophers. I think the Quick-Shok killed the most instantly though.
