hey everyone just trying to get some opinions on the subject. i have read a few different methods but what i have picked up is that you do actually want some copper fouling in the barrel. my dilemma is that this is my first brand new rifle and i not knowing i was doing anything wrong ran 100 rounds through it within the past weekend. now i am wondering if i have damaged the barrel by doing this or where i should go from here. also are there any no nos in this department. i have always used hopes no. 9 on all my rifles and cleaned them every 100 rounds or so and used a brass brush. all of my previous rifles i was happy with moa groups though and never expected any more out of them. lastly i have noticed the more rounds down the barrel of this rifle the tighter groupings i have been getting. any info is appreciated as always.
