I'm going to shoot this stuff again Saturday, if we can get a sitter. I've had some comments on the other board that grocery store gelatin doesn't yield the same results so I plan to fire at least one shot of .40 S&W 180 gr factory Gold Dot into it from my Glock 22 to help establish a baseline that we can compare to professional tests. On the one hand I'd like to get on with testing lots of other loads but on the other hand I think I need to address the concern that my gel may not yield accurate results. To that end I was thinking that I could probably get two shots into each block, for a total of 4 shots. So what do you think? Should I shoot the block four times with .40 or is one shot sufficient to tell us whether the gelatin is close? If I only shoot it once with the .40, what other load do you want to see tested? The two I'm most interested in seeing are Buffalo Bore 10mm 180 gr JHP and my hand loaded 65 gr Game King over 24.0 gr of TAC at about 2,950.
