I have a Remington 700, 300 win mag that has a Leupold mk4 6.5-20 on it. I also have another gun with the Steiner T5XI 3-15 on it that seems like much clearer glass. My question is, will I have enough adjustment from the Steiner T5XI 5-25 model 5126, if I buy it, replacing the Leupold, to go out to a mile on my 300 win mag? Thanks in advance.
