The record for the longest confirmed sniper kill was made with a MacMillan Tac-50 rifle, if that's any indication of what the best long distance rifle would be. Of course, given the broad nature of the term "gun", and that it's often applied to field artillery pieces, as well, one could just as easily say the M1 240mm howitzer would be the best.

The late Eddie Albert who played Colonel Thompson in the film was shot by either a sniper or by a machine gun .
There are no (Kept) records for this category. However the PCP (PreCharged Pneumatic) Class of air rifles will have the longest range.
If by mini gun you mean a "miniaturised" version of the M167 Vulcan 20mm antiaircraft gun, the answer is "No" on the original Sniper Elite.

The first and easiest opportunity to get a Sniper Rifle, is from Jake in the Hub.
an assassination sniper gun works by simply using an hammer to "bolt" a very large bullet to a target, which can easily kill someone in one shot. these snipers take a while to reload since most of the work of the sniper is more put into a one-hit kill meaning and accuracy than others. a sniper basically works like a normal gun expect its bullets fly much faster and farther and are much larger than normal guns bullets. an assult rifle works nearly the same way, expect that the rifle fires smaller bullets faster and without much reloading.
