Barrel running in procedure

[Marmite5]

I use it on my Target Rifle after every outing.

Does it affect your accuracy for the first few fouling shots after a clean mate, my HMR always does the first cold bore shot high and right, then every other shot bang on target

Not noticeably but we occasionally go to the zero range when at Bisley to do some blow off shots and foul the barrel.
