Hey good folks. New here and to “long” range shooting. I say long range loosely. Longest shot I have is around 500-600 yards. Anyway. I ordered this scope after great reviews. It’s an Athlon Argos btr 6-24x50. Mil. Mounted on a vanguard 270 wsm this morning. Took a few shots today and after each shot I have to adjust the parallax. I like this scope as it’s the first one I’ve ever bought with that much power and ffp but is this common to have to adjust the parallax after each shot? If so I’d rather go back to old scope just in case I miss and have to get back on target quick. Hard to hit a running deer if you can’t see em.
