ive broke barrels in the propper way. just take brabd new barrel unfired other than test fired at the factory and shoot atleast 50rds through it without cleaneing. load a bunch of ammo test loads and fire more rounds then when you get closer to 100rds clean it out good. nothing specail just bore cleaner a brush
ore possibly just use a bore snake its just brush on rope drop alittle bore cleaner on the brush section and drag it through a few times and your good to go.
i preffer this method.
but i have also broke bores in by cleaneing between ever rd fired for about 20rds, then clean every 5ds then every 10 and so on till you feel comfortable that its broke in.
ive used this method oin rimfires and center fires.
my old 22/250 got broke in by cleaning between rds, my 2506 probably had a few hundred rds through it before it saw a brush. the 27wsm was cleaned between rds when new. and my new 220 has been getn negleted to fullest. i rarely clean this bore.
all in all i can see no difrence at all.
i also think cleaning bores is way over rated. if your putn rds through your rifle on consistent basis id say clean every 100 maybe more.
i do believe if the rifle is going to be sitn for a period of time the bore should be scrubbed and oiled. only to prevent rust and nothing more.
