rangefinding scopes question- the ones that show range & poi - how do they work ?
it seems they would have to know the caliber & velocity to give actual bullet drop
I ask someone who was using one -& he said it learns what ever you sight in with
obviously - all you need is money to buy one -not ballistic information
I dont want one -I just want to know how they could possibly send a 223 & a 300wm down range with accurate poi info
or for that matter 2 differnt bullet weights from the same rifle
