The Impact of Losing Zero – Causes and Mitigation Strategies

[HuntHarder]

No problem.


The 6cm barrel I have now had a near .2 mil shift somewhere between 60-80 rounds. Adjusted, and has not moved in over 200 rounds. The 22CM had a shift of .1’ish mils around 50 rounds in. We had one of the S2H school tikkas in 223 have a shift at somewhere between 100 and 200 rounds.

It’s a thing until they stabilize.

I just had this happen to my Tikka yesterday. It was around the 200 rd mark and I had a .75 moa shift down. Velocity is staying consistent now, but I did have to adjust my zero. Part of it could have been a low zero, but I'm certain it wasn't .75 low. I also noticed this barrel is on the " fast" side. Less powder to hit pressure than most people's accounts, and higher speed.
