Re: When do u clean? Time vs. # of rounds
Pretty much similar to your routine, every forty when we are shooting on steel, might put 100 to 120 per rifle per session so three or four cleanings. Good for letting a hot barrel cool down a bit.
Always clean and oil before putting away, oil or RIG in the bore if the rifle is being put away for an extensive period, if going to shoot soon just a light oil.
VERY IMPORTANT to remove oil from chamber, my new 6.5-284 does not like any oil in chamber, case head mark to show that, after second shot no marks.
I am using MT Solution now, really like it for carbon and copper removal.
Best to adopt the mindset that cleaning is an integral part of shooting - gotta do it to maintain best accuracy.
