During the winter I tend to shoot a fox every four days from the Velux in the attic. I have an alarm set up over a chicken carcass which gives me a proximity alarm and I go up to the attic and pop off the fox (I do miss sometimes however). I used to exhaustively clean the rifle after every night's shot but I wonder if I maybe eroding the bore or causing some harm by excessive cleaning. What harm would I be doing to just leave it and clean once a month after 4 or 5 shots? The attic is very dry. The rifle is a stainless steel Tikka and is v accurate but takes 3 shots before it starts to group with 5 shots under 1/2 inch at 100 meters with reloads.
