I would have no idea...but..a guy I know...
Kidding aside, a fellow Ontario groundhog shooter I'm friendly with is in the process of leaving the military, and a good friend of his is a sniper currently deployed. (based on the last time I asked) I don't "know" the guy, but have had a number of email exchanges with him as he's a varmint hunter too, and an experienced rifle builder. I'm a small-caliber fan (.20 cal/.223) and a huge rimfire enthusiast...and he seems to be neither, but the input is welcome nonetheless.
Anyhow, while I have a fascination with the military and probably have 100 dumb questions to ask, I avoid the temptation.
So yeah..I guess I'm "one of those guys"...sort of.
