I have recently purchased a new rifle that will b used for F class comp, ive read a little about properly breaking in the barrel but still unsure on the proper procedure, what is the proper way to do thisgun)
I agree, read Barrel Break-in and Break-In & Cleaning. At the bottom of the Krieger page, you can see the frequency stated. One thing is sure in all break-in procedures, there will be a lot of cleaning.
