So what if the Winchester is lighter, that's just one advantage compare to what the Tac can offer. It doesn't mean that a Winchester is lighter it's already the better sniper rifle to use. heck, its not like the two men would be moving around that much and luggin their rifles (that's not how historical sniper battles are done anyways). If you know these two, most of the sniper battles they were at (including their epic duels with counter snipers), were done in stationary positions with little to no movement at all. So the Winchester's weight would be just a small factor.
