When I joined the Army in the early '70's Canada had 3 different small arms manufacturers in the country. By the early '90's we had 1!! Guess who? Thank you Mr Trudeau! At one time part of the TQ6A course for Ammunition Techs included a tour of IVI facilities in Valcartier. Each course upon completion of their tour constantly brought up more and more quality control questions to the point where the invitation to tour the fascilities was permanently withdrawn.
During the late '80's, when IVI got into the mfg of 5.56mm, large number of lots failed proof testing to a point where the Jacket was shedding off in the barrel. As each lot of failed SAA could be as large as 2,000,000 rds, IVI was given permission to dump south of the border, it appears the americans will buy almost anything for a cheap enough price.
I was shooting Service Rifle out of Chilliwack at this time and was regularly talking with guys that were hopping south of the border and buying this stuff at US gunshows and bringing it back to Canada.
Recently SNC Lavalin has been bought out by General Dynamics (GD)
http://www.gd-otscanada.com/html/en/products/ammunition-small.php Having worked recently with GD people on a regular basis on a number of DND projects, because they not only support the CF but the US Army as well, their quality control is number 1. One can only expect that GD does a house cleaning in Valcartier as the US Army won't accept garbage.
In regards to the "arm chair commando" remark, obviously your level of maturity did not improve because of your tour. Many people who work in the Ammunition and explosives field in the CF, have spent a large amount of time working EOD and have probably had their sphincter muscles far tighter than you can ever imagine. Also a surprising number "Log Wogs" these days are ex combat arms, who also have a wide variety of field experience. A large amount of time and experimentation goes into the selection of the items that the average soldier carries into the field. If it doesn't work, you write a report, so that it can be investigated and improved upon, not just whine about it.
