Is break-in time really needed for factory guns

[BlueMoon]

I agree with what the other fellows said. The last couple of new rifles I bought were de-greased and had some JB paste pumped through the barrels before I shot them. I use CR-10 or Sweet's for heavy jkt fouling, not leaving it in the barrel very long. And Butch's Bore Shine for common fouling along with some other brands I seem to pick up to try something different. BM
