Home Forums Hunting & Shooting Ask The Gunwriters how much bump will cause a rifle to lose zero

I have a Leopold 2x7 variable on a 30-06 that I dropped from a top bunk onto a hardwood floor (about 6 feet). It hit really hard on the scope and bounced a couple feet and hit again. It was only off about 1/2 inch at 100 yards. Around here, that's not enough to even worry about. A buddy of mine has an old "made in Japan" Tasco 3x9x32 on a .308 BLR that he has hauled around on handlebars of an ATV in some really rough country for 20 years. It has never had to be adjusted once in all that time. He hasn't dropped it hard or hit it, but it gets a pretty good bouncing around on the 4 wheeler.
