Did I break my scope?

So, long story short: I was back-country hunting two weeks ago, and while climbing up a ridge I wiped out hard. Rifle slipped off my shoulder and landed side-on to a pile of rocks. The impact was hard enough to leave a 1" wide, 1/4" deep dent in the pistol grip, and put a 3" crack along both sides of the barrel channel from the tip of the forend back.

The scope appeared to have avoided damage, with no dents or dings that I could see. The barrel and receiver also appear undamaged. The walnut appears to have absorbed all the impact, apparently.

However, on firing a group afterwards to test the POI shift, if any, I found it had shifted a full 5" right and 5" up at 50m. (No opportunity to test POI at a longer distance at the time) I was able to get it back to POA/POI alignment with the expected amount of dial twisting, and shot a three-shot group that was close enough to minute-of-deer for the purposes of continuing the trip. Scope is a Zeiss Conquest 3-9x40 I bought about 11 years ago that has been rock solid until this incident, in Warne Maxima rings and bases that also appear to be tight and undamaged.

I realize that I need to shoot it quite a bit more to rule in or rule out any damage, run a box test, etc. My question is if a full 5" deviation off zero at 50m is reasonable or not, considering I put it to an admittedly hard impact? Is it even worth testing to see if it will hold zero going forward, or should I demote it to a spare?

I'll need to replace the stock on the rifle, just wondering if I should budget for a new optic as well.

Thanks in advance for any input.
 
If you were able to get it back on zero seems like it should be fine. 5" at 50 is about 10 moa of movement.

So it tilted 1/6th of 1 degree... Id just shoot a few groups and make sure all is well.
 
You gotta figure out what shifted. I would bet on rings or base. If you pooched the scope, you would find out when it will no longer hold zero, shift suddenly, catch on fire, etc.

Keep in mind that you may have shifted the action in the stock, resulting in the change of impact.

Just to bring it to a close in case anybody has a similar problem: looks like it was the base after all. Shot a few rounds to confirm POA/POI for a box test and lo and behold the front base was wobbly as all get out. Loctited back down and all appears well. Thinking I may have omitted to use enough (or any) loctite when installing the bases. Lesson learned.

Thanks for the input.
