I looked it up. The Mcmillan TAC 50 is made in Arizona is the standard sniper rifle used by the Canadian Army. It's a bolt action rifle and shooting that big 50cal round. It must kick like a mule. Furlong's record was beaten by a Britisher shooting 338 Lapua round. I believe the 338 Lapua was developed by one of the Scandinavian countries. I've been hearing great things about the 338 Lapua in that it has a modest recoil for its power and distance. It is supposedly the round adopted by the Air Force snipers. I have a low regard for Air Force snipers. But it was the Air Force who first started buying the AR 15. They might be on to something now
