First off, Rancid, can't comment on the identity of the guy but suffice to say, I too have heard rumours of this kind ever since I started playing.
I have also played with guys who regularly turned up their guns (not me, I might add) and some who ran close to the limit, say 298 and then turned it down when they came in for chronographing, so I know this shi#t does go on.
Now those people who did that crap make their own decisions as to what they do, I am not their moral arbiter but I also think that when a team decides on a policy of cheating then we are in a whole new ball game (pun intended).
I am not minimising in any way the cheating that I was witness to, far from it, it was despicable but we must acknowledge that when teams have it as a working component of their game, then we are in deep water.
I think for every device we can think of to build into the gun (standard chip sets etc) then they (the cheats) will find a way round it.
I'm afraid I harp back to rigorous and frequent on-field chronographing.
Darm, these people are not doing it to hurt other players, they are only doing it to gain an advantage !!!
And appealing to their better nature mate, ain't gonna see much success this side of the next expansion phase of the universe.
Oh and Bud, I don't think I have really thrown myself in a wasp's nest because I don't run with a hot gun (well never knowingly anyway) but I suppose I could be criticised for not saying something when I saw team-mates doing it but hey, come on, I ain't the sport's enforcer or moral reference point.
And hey Magued, perhaps the reason you have never seen it, is because by it's very nature it is covert, hidden, hard to detect and so on.
It ain't meant to be witnessed, therefore don't be too surprised that you have never recognised a re-configured chip set or a re-programmed data set when the guy is shooting at you or you are firing his gun over the chronograph.
Get an oscilloscope out and u might have a chance !
