Hi...I've only taken my x-bolt .270 to the range 4 times, but today i was shooting an inch high from where i had been the previous couple of times. I have a Bushnell Elite scope mounted with 4 screws on each mount and everything seems tight. I was still grouping, but an inch off where i had been. Im a very new shooter and this is my first gun with a scope. Is it possible I was doing something different today than i had been? Im not a pro yet, so Im thinking it could be the lack of muscle memory. Is it common to make minor adjustments to the scope (2 clicks) now and then? Sorry if this is a stupid question, but I didn't know where else to ask. Thanks.Oh, I was using the same ammo as i always had.
