I am about to purchase a Leupold VX-3 and can't decide whether to go for the 3.5-10x40mm or the 4.5-14x40mm. They are both roughly the same size, weight and price. The 4.5-14 has the extra mag, better eye relief (it's going on a 270 WSM) but somewhat reduced FOV figures. It will mainly be used on the hill and every now and then on a high seat. If anyone has experience with these I would appreciate any advice.
