I have a VXIII in 3.5-10 on my Browning stainless stalker in 325wsm. Sighted in correctly for the load and with the dial set as it should be, it will make short work of long shots. Have used it using the different elevation marks to take several deer and an elk that were between 300-400 yards. Animals were all ranged and then just split the 300 and 400 yard crosshairs, all three were nuts on one shot kills. Have played with it at the range out to 550 yards quite a few times, and it works quite well. The other elk I shot with the gun was at 200 yards, so no need for anything but the central crosshair. I love the scope, but it does take some getting used to. I feel it's very easy to get familiar with if you just go to the range and play with it.
