Just sometimes WTF ???

[Pappabear]

We went out today and had two guns shoot 3 inches low and 1.5 inches right. These guns were zero'd many months go and again last week. Now all of sudden they shoot 3 inches low and 1.5 inches right. Not one gun but 2, one is my Geissele SD and the other is my FN SPR that both shoot lights out.

Have you guys got this craziness ? It has happened before but still WTF?

We have seen this before and our other guns were spot on. God help us all. Im just going to watch Lone Survivor.

Just had it happen on Friday. Steyr AUG M3 zeroed at 50 indoors last winter.

Took it to the 100 yard range on Friday and I was aiming at the center diamond and the hits were all over the smaller diamond in the upper left hand corner.

You can see me walking it in on this target as well as the initial 5 shots in the upper left. (One round nicked the paper nearly off the target.)

How it goes from zeroed at 50 to this is beyond perplexing. Wasn’t even close and both were using the same 77gr hand loads so it ain’t the ammo.

Using irons or red dots/scopes?

[Slater]

Could temperature and/or humidity be a factor?

Using irons or red dots/scopes?

My AUG sports a Vortex Viper 1-4x. Pretty sure PB is using scopes as well only nicer.

Victim's of climate change...we're doomed.

Different ammo or lots?

What was the temperature when you shot them last, and today? Did you shoot them at the same place? Same load?

Just had this very thing happen a couple of weeks ago. I put it down to different ammo and different velocity intersecting with the twist. Ever shoot 6 or 7 different charges while trying to find that perfect load and watch it rotate around the POA? I have seen it a number of times with different bolt guns.
