So while zeroing in my rifle the other day I was trying to get consistant shots at 150' with a stock UTG mk96. Although its not upgraded yet it can reach that far but starts to hook left or right. Hopefully i'll be doing the TDC mod to get a straighter shot. Any who, I notice at my closer shots I had to aim lower since the hop up made my shots high. I'm a hunter so i understand i really don't want to have to aim way low to hit my target, but rather aim a little high for farther away targets. So my question is, what do range do yall zero your rifles in at?
