Zeroing my scope this weekend

[rtlltj]

Just mounted a Nikon buckmaster 3x9 with a LT-104 on my flat top AR and sighted it in this past weekend. I was shooting a target that has 5 4 inch circles 12 inches apart. Is it normal to sight my shots into say the bottom left target at 100 yards and then have the point of impact be off by a few inches when moving to the top left target at the same distance? I didn't think a vertical movement of my target around 1-1.5 ft would change the point of impact by that much.

That is not normal at all - your zero should remain for a given distance not matter how many different targets you engage at the same distance. Did you check that all mounting hardware was properly mounted and torqued?

I agree, it sounds like something is loose.

Alright, I'll retorque the ring screws and test it again next weekend.

Check the base screws also. It's usually those that are loose.

The LT-104 is a Quck Detach mount. Make sure the locking lever is adjusted to give the correct fit. See directions here: http://216.23.214.70/instructions/instruct.htm Sounds like it may be loose.
