i tend to agree with liambobbi. The rifle is just a tool... The highly trained person pulling the trigger makes it a sniper rifle. I don't remember the exact numbers but our sniper course only has like2 weeks of marksmanship out of I think 9 total weeks to become a sniper. Just because I need a very accurate rifle to hunt at 400 yards here on the Colorado plains doesn't mean I have a sniper rifle. It just means those animals can see you from a long ways away.
I had the pleasure of shooting a M110 while in Afghanistan and to me it was just like shooting any other rifle (except the silencer..
) I have and of course extremely similar to shooting my issued M4. I couldn't get the full potential out of that rifle like he could... because he's trained.
