One tip: clean the barrel good before firing. Break it in with frequent cleans with copper removing types like Montana extreme 50 bmg solvent. I clean and shoot 3 and repeat 3 times and then 3 , 5 shot groups and clean and done. Then just clean it when accuracy starts to suffer at least.If stored for long periods, clean it well and use a bore guide and then oil bore.When you go to shoot it dry patch the oil out.
