Scope mounting issues

[Grundy53]

I'm not sure what is going on. There are several variables, so I'm having a tough time narrowing down the problem. I just got my rifle back from getting a new barrel and bottom metal installed. I mounted a new to me scope. So, three new factors. I went to sight it in and ran out of down adjustment with it still shooting 9 inches high. I went home and swapped the bases and rings. Used a laser bore sight and now I'm running out of up adjustment and the cross hairs are still too high (so it will shoot low). Swapped to a different scope and rings. Same problem. I thought maybe the stock and action weren't seeted right. So I took it apart and put it back together. Still the same problem. What should I do?

What kind of scope? If it's one that uses shims for a zero stop there could be shims installed that are limiting your travel.

Nightforce SHV 4-14x50. I looked and didn't see any. The other scope is an SWFA 3-15. It doesn't have a zero stop.

Is it a pic rail, or direct mount rings? If there is a 20 moa base built in and it or the rings are backwards that could cause an issue. not sure with out more info on specifics on rifle and mounts.

Did you mount it on a 20moa rail?

Photos may help as well as Scope Type and if it on a rail or what. Also I am slightly confused as it was shooting high and now you are saying it is shooting low?

Remington 700. 2 piece picatinny. Neither were 20 moa. Nightforce X-treme duty and Warne Maxima rings.

Yeah, I'm confused too. I'll get some pictures

I'd lose the 2 piece and get a 1 piece pic rail and bed it to start

It could be me but the one picture that scope looks like it is head Nose down. Maybe remove the scope and place a good straight edge across those two mounts and see if one is definitely higher than the other. Other than that a one piece rail would be very good starting point.

I'll do that. I just ordered a one-piece also.

Are the front and rear base's swapped? I've never seen that much hang over into the action area on a 2 piece base?

That is what I figured happened.

Definitely not. They don't have the same screw pattern. So they aren't interchangeable.

Looks pretty straight.

Well you can do the same basic check with rings on the bases and see how that goes. You can try just the bottom half of each ring and use the straight edge and rule all that stuff out. Other than that I don't have any knowledge on the scope itself maybe somebody else does.

Have you actually shot it. My bore sighter was far enough off I quit using it. Only once have I had an issue of running out of adjustment.

Is the barrel tapered?
