Hello everyone, i am now taking on my long range shooting very seriously and starting to put all my research and newly acquired knowledge of long range shooting into the real world. My rifle is a rather simple setup ive had for a while. Remington 700 cdl .300 win mag with a Nikon buckmaster. Yes I know its not all fancy but definitely a solid setup for me and has served me well. Last time i shot my rifle i had it dialed in perfectly fine, at 100 i shot about .8 and i was happy with it. Hornady 165 gmx. That was last summer though.....went out today and was definitely not where it was supposed to be in terms of POI. I will be shooting A LOT more so i can really get my long range fundamentals into order. But why did my zero get all weird? Same ammo was used...maybe it was just me since i dont shoot it as often as i should?
