I am aware that the point of aim on most rifles will be different when shot with a mod on and off, but does anyone have any experience of a rifle changing point of aim after the mod has been taken off then put back on?
The reason I ask is that I zeroed my Tikka 595 with PES mod back in February, then took it out that evening and took 2 roe no problem. On the advice of the stalker I was with, I removed the mod overnight to allow any trapped gases to escape without affecting the bore.
I fired at 2 more deer that trip without success, the misses being put down to me. After another trip with a couple of less than satisfactory shots, a morning on the range showed that the rifle was shoot 3 inch to the right and 3 inch low. To my mind the rifle has not taken any knocks that could have put the scope out.
Can removing the mod been changing the point of aim? I have left it on after the last zeroing session, but I always try to look after my kit and would prefer to strip the rifle and mod down after each trip.
