I just broke in my R700. I used reloaded ammo with 147 gr FMJBT I use for fun in my semi autos. I did follow the following routine: shoot one for sight in, clean to get the carbon out, shoot one more, brush only for debris and carbon and scope correction. I did it for five rounds at 25 m and had the scope dead on and then i repeated the process for another five at 200 m. At the end, the cleaning of the barrel with patches and solvent showed much less carbon deposits and the scope was sighted in for 1" high at 200 m. Does this involved process break the barrel in better than just shooting the rifle? Probably not but it makes it easier to clean the barrel well at the end as the sighters and break-in shots do smooth out the barrel a bit. Next time out she goes with 168 gr and 175 gr SMK's for grouping.
