I recently bought a new Rem SPS 220 Swift, I went straight home from picking it up, stuck the crackers in it and banged em off over the hi-lux bonnet "up the back",i have done the same with any of my rifles...I can tell you that this thing topped with a L 6 x 18 scope does the job and i have never seen the need for the elaborate processes above myself..each to their own opinion of course. My 7 mill is near on 30 yrs old with the same barrel and the same was done for it,the old girl still shoots an inch with Winny factory rounds to this day.
