Got a newbie question for you guys. Got a 300 wm that is a tack driver and have been shooting here in the PNW at 1100' elevation. Headed to Wy in October and the elevation back there will be in that 4500-5500' range. How much POI change can I expect with this elevation change? Is there a rule of thumb for this? I got the tools (RF) that will make this correlation for me but just looking for some insight prior to our trip.
