What caliber Handgun?

Has anyone heard what caliber was used in the shooting caught on tape outside of Blake's trial?

Some people have watched slow motion of the film and say there were 8 shots fired so it must be a 22. A larger caliber would have had more effect too.

He had 2 revolvers & witness saw him put 1st revo back in his pocket before he was caught on tape emptying the 2nd gun, so I'm guess smaller caliber...maybe 22 or 32??? Yeah, the new reports I've seen haven't given up the caliber but I'd think that a 38 at that distance would have put the guy down after the head shot easy :scrutiny:

I thought I heard on the news he was shooting a .38. Man, I've never seen someone duck and weave so fast in my life. That guy did a great job of pitching around that tree.
