I have a Bushnell elite 1.5-4.5x 3200 Firefly on my Marlin 1895. The gun isn't practical past 200 yards, but it's really good for shorter range as I think all can agree. Go with the lower magnification for best FOV. The high magnification craze is way overdone. It does not take 9x to harvest an animal at 200 yards lol. Most guys leave their scope on the lowest magnification as they should until the shot presents. 45-70 does not need 9x, ever. Nor does it take 14 or 15 x to do it at 300 yards. Just a way to sell more scopes. That's reality based on my experience and not armchair discussion.
