I tried my first "arbitrarily distanced shot yesterday. I set up a 10" gong and drove down the dead end road I was shooting down until I guesstimated I was between 400-500 yards. My dinky rangefinder would not range to the target so I had to range out from the target around 200yards then range to my car to get the distance. The range ended up being 412 yards. I used the "MD Ballistics" iPad app(I highly recommend it, makes calculation easy) to calculate the drop. I'm shooting 175 SMKs over 45gr of Varget out of a Remington 700 SPS AAC-SD in .308. The app called for 33 clicks up on my Zeiss Conquest 3-12x56mm FFP #8 reticle. I counted off the 33 clicks and set up prone on the roof of my Jeep with a Harris bipod and a rear bean bag. I was able to put three round in a row on target! I would have shot more but ran out of ammo. How satisfying it is to see that gong swing and hear the "diiing" a few moments later! I plan on slowly working my way out towards 1000yards. My gun has a 20 inch barrel so I'm not sure if I'll have the speed to get out that far but I'm going to try! I am also quickly seeing the benefit of a mil-dot/hash reticle, target turrets,and a zero-stop! Counting click isn't so fun,haha! Good news is my Zeiss is great at returning to zero after adjustment. I've emailed Zeiss to see if it's possible to add a mil type reticle and target turrets to my scope. I was curious to know what size and style of targets are usually used for practical field comps?
