I'm using the CCI Quiet-22 Segmented hollow point.
I drifted through a few different ones, and I don't have an exact test on accuracy. However, at the ranges I shoot this does well on hitting what I aim at.
Two big reasons for using it:
1) Segmented bullet. I can say wow to that. It's devastating on the game I've taken with it. The opossum eating my cantaloupe found out last night.
2) Copper coated bullet. Keeps the can cleaner by using something that isn't pure lead. Also keeps the hands cleaner, etc.
They also sell this bullet in a higher velocity version I like.
