Gelatin proof?!
Gentlemen,
If you don't have any real experience, I urge caution when you referance the "low penetration" of the lowly target wadcutter.
Underpenetrating is not a property that I would assign to it. I can tell you that a factory wadcutter will completely penetrate two solid core doors and more. So it is intuitively obvious that wall board will offer far less resistance. Having actually used the lowly wadcutter to kill game (shot from J frames), I must tell you that Mr. Kennan is correct. Even a slow moving wadcutter is nothing to stand in front of. Back in the early-80's, I experimented quite a bit with reverse HBWC handloads. Accuracy is mildly improved by seating the bullet further out, say half the length of the bullet. Even then, you can only expect groups of 6 - 8 inches at 50 feet. Not a problem a social distances but I shudder the thought of having to explain to a jury why the factory loads weren't as good as my homegrown "Manstopper" loads. What to I carry? Depends on the gun in hand. Either 158 gr. LSWCHP +P or the lowly wadcutter. I have no doubt, if used by cool hands and head, each will get the job done. Stay safe.
