I carry a snubbie with WC.
Mine has fixed sights. If I use a heavy expanding bullet, I don't feel it would have enough velocity to expand right. If I use a lighter, faster bullet, it hits the target way low. An unexpanded HP is called a round nose. I choice the most effectice bullet that is not dpendant upon it changing its shape on impact.
Factory target wadcutter ammo is soft lead, and very low velocity.
Hollow Base wadcutters are soft lead, and the skirt comes apart if loaded at high velocity.
Hollow base wadcutter loaded backwards is essentially "prefrag" , and tends to tumble, for an effective accurracy range of about point blank.
I use a cast DEWC (double end wadcutter) that is handloaded to 900fps, which is just shy of, or just inside of the +P range. If you are a handloader, you've got it made if you can find data with full power WC loads. It took me a while to develop what I'm using, and some really old data.
I would consider most factory wadcutter ammo to be too light of a load, but it is my understanding that Buffalo Bore now makes a warm wadcutter not +P for personal defense.
