Hi all i am fairly new to long range shooting and this afternoon i was shooting my 300 RSAUM and when I changed my magnifacation from 14 to 8 my poi changed by 2 foot low. Is this normal i had thought when you sighted your rifle you did it at the highest magnifacation. If i am wrong please somebody help me I am very confused. Everyone on here is very skilled and I trust in many peoples opinion. Thanks for everyones help.
