I've read PO Acklye's take on bullet spin, that he figured rotational spin had a lot to do with killing power, or hydrostatic shock. The faster the twist, the more the spin, and the faster the FPS, the more effect the spin would have.
What's your take on this?

Extry RPM do make frangible projectiles unhinge faster.

For the Goo Launching Tourney,fast twists rule...............

I'm sold on fast twists with light bullets for varmints. I'm using 55 gr. VMax's in a 8 twist barrel.See the photo of the "doughnut squirrel" in this thread.
