Card wads are quite useful. Sometimes.
Just don't use them with your muffler!
No, won't be doing that.
A couple of pics for Mathman of soft bullets and what they do.
This is a CB short bullet, BHN of 8 recovered from the neck of a largish hog after it penetrated fully thru the skull and brain. MV ~710 fps
The skull:
A 300 grain pure lead paper patched .44 Mag bullet of pure lead, 1600 fps at the muzzle. 1.5 caliber ogive radius with a very minor flat on the nose of 1/8th" or there abouts. I don't have a pic of the bullet unmolested. BHN 5. Hit a deer at ~75 yards, broke both forelegs, 5 ribs and cut the heart in half near the top. Retained weight is 297 grains.
I have another of similar form that did a hog of about 125#, high on the right shoulder found under the hide in the back of the left ham. Bone carnage included shoulder bones, ribs, vertebrae, the hip and socket of the left ham bone. Retained weight was about 285 grains, impact at about 15 yards.
The 30:1 alloy runs about the same hardness as the CB short bullet above and this particular bullet will have a BC of about .300 on average over the flight of the bullet to 100 yards. In this affair placement trumps other considerations to a very large degree. It will expand at the higher end of the velocity envelope.
