The lesser wind drift of the 125 grain bullet is the connection,and it is becoming popular for use on the shorter ranged targets, 100 and 200 yards. The drift difference between the 110 and the 125 at the shorter ranges isn't much, but there is a difference and that difference is increasingly apparent as the range and wind velocity increase.
Around here, unless you are talking about calling conditions, a 10 mph wind is a very mild wind, 15 to 20 is more common out in the open in December, January and February when guys are driving or dogging coyotes. Of course, wind drift with bullets suitable for varmint hunting is one of the main reasons that few people use the .308 Win. for varmint hunting of any kind if they can afford something more suitable, particularly in flat, well populated terrain. But, if you are inclined to use something other than an optimum cartridge for hunting coyotes, you owe it to yourself to use a varmint suitable combination which handicaps you the least. That means the 125 grain bullet.
