I know we'll keep butting heads on this one, so we'll have to agree to disagree. I think as more time goes by, we'll see who wins. My money is on the 5.7.
I don't think we're butting heads in any negative way, and I'm open to arguments in favor of the 5.7mm because I would quite honestly like to have somebody convince me that the 5.7 is in fact a viable service cartridge, if this is indeed true.
I need to read/hear more from the ordnance/ballistics experts in Canada, the U.K., and France. I know nothing of the testing done in the latter two countries, but I personally know experts from Western Canada who have tested and rejected the 5.7mm repeatedly for their agencies. The RCMP have rejected it at least twice.
Like I said, I've got messages out to a number of people in the industry on this question, as it seems that the assertions I've read on this thread indicate I've got a blind spot here. I'm going to correct that blind spot, and if my current and previous position needs to change based on real evidence, I'm going to change it.
