I normally do break in the barrel on a new rifle,but I keep it simple.I start with a nice clean bore,shoot,and run a wet brush ,and a dry patch through it after each of the first two shots,and then do the same twice more after after shooting twice,and then I shoot two series of five doing the same,and call it good enough.I recently bought a Howa 1500 mini action 223,and although the booklet that came in the box does not cover break in,I have noticed on Howa's online info that Howa calls for a pretty tedious break in .They want the bore cleaned with solvent,patched,and then cleaned with ammonia based cleaner after each shot,and then wait until the barrel is completely cooled down before shooting again.They want this procedure followed after each of 10 shots,and claim that by doing so it not only insures future accuracy,but also makes the rifle much less affected by point of impact changes due to a hot barrel .I am just curious as to whether or not you folks would follow Howa's instructions,or give it the same break in as any normal sporting rifle.
