An idea on how to get better performance from sub-sonic bullets...

I was thinking of a way to get sub-sonic bullets to perform better. So here it is...

Take a Sierra 200, 210, or 240 gr. bullet and score the shank approximately 2/3 of the way to the ogive with a tube cutter. It you score the bullet almost all the way through the jacket material, I suspect the the bullet will break up when/if it tumbles inside the target. This should significantly increase the preminant wound channel thereby incapacitating the target more effectively.

This will deform the bullets shank a bit by making it a bit larger than 0.308 in. immediately near the cut but sub-sonic loads are low pressure and firing the bullet down the bore will just swage the bullet back to the correct diameter. One drawback from this that I can think of is that you might quicken/increase the fouling of the barrel. I think that regular barrels cleaning should be able to remove this though?

All comments welcome.
