[QUOTE="Varberger757, post: 865008, member: 66992"] The increased copper fouling in your 7 WSM might have different kind of reasons. [FONT=Calibri]- - [/FONT]The kind of bullets you use. I’ve personally made the experience that some bullets give more fouling to a certain barrel than others. Especially interesting in this case are monos made of copper like the Barnes etc. They have a tendency to give more copper fouling than the usual ones. So change the type of bullet and check the results! [FONT=Calibri]- - [/FONT]Lighter bullets with higher speed may give more fouling. Coefficient of friction. [FONT=Calibri]- - [/FONT]Condition of your barrel? New or old? Have you carried out a reasonable break in of your 7 WSM? A little advice at the end. You should not compare two different rifles with two different calibres due to their characteristics! That’s like a comparison of apples and pears. I hope you’ll get the problem solved soon. [/QUOTE]
