I think that the bottom line to all this is that regardless of how well the rifle is capable of shooting, you now have no confidence in it.That’s what I have always done, all those testing started because i noticed a strong tendency to poi shifts both at the range and in a single field test: i was hunting, keeping shots inside 200
For good measire being a new rifle, i took a for buck and then i decided to shoot a couple shots to confirm zero with the bipod resting on something that wasn’t concrete. Both went high 1 and a half inch above what I was expecting. That’s when (luckily) i decided to do some more tests and the problem showed. 1.5 inches outside POA at 200 can easily translate in missing a quartiering roe or wounding it, that’s not acceptable for me. With my old rifle i went to the range maybe 10 times in 8 years to check zero after deep cleaning after rain. For me a rifle is just a tool and it must work reliably. I couldn’t care less about shooting groups at the range if not to confirm my tool is up to the task and this rifle doesn’t seen to be
That will always bother you for as long as you keep it.
