I've only ever broke in one barrel in my life and I'd have a hard time complaining about accuracy it any gun I've ever owned. The one I broke i was a 700 in 6.5x06 and if Breakin did anything, I have no clue what it was!

if there is a manufacturer's recommended procedure, i would follow
that just to avoid any possible future warranty issues.
otherwise just put bullets down the chute

Shoot one round and clean the barrel of all Copper. I use Bore Tech CU+2 or eliminator - your choice as they are both excellent copper removers. Do this 25 times or until no sign of copper - which ever comes first. The break-in procedure is not for accuracy; itís for ease of cleaning once broke-in. Most chrome moly, hammer forged barrels are rough, so I doubt it will break-in like a match barrel.

Breaking the barrel-in using this method will reduce copper fouling, how much depends on the roughness of the barrel. Takes the better part of a day, but Iíve done it on many chrome molly barrels and a few cleaned up but most were copper strippers. Iíve never had a match barrel that didnít clean up nicely after 8 to 21 rounds.

Tubbís has some fire forming rounds that do a quicker job of it but a rough barrel will just copper foul, some more than others, but breaking-in will help all barrels foul less. At least that has been my experience over the past 50 years of shooting, both competitive and plinking.

Back when the "break-in" craze started I jumped right on it's bandwagon! After the dust settled all I accomplished was to wear out a couple a cleaning rods and end up with an arm like a Go-rilla's!

So, I put breaking in a barrel right up there with cryo and moly coating on the usefulness scale.

Nowadays, if I do anything, I stroke the bore a bit with JB Bore Compound and call it good.

Keeping the barrel clean is the most important step for accuracy.

Richard, that gorilla under arm smell must of had a negative effect on ya. in that you didnít give your rougher than a cob barrel a couple thousand more strokes.

Cryo treatment usually doesnít do much for the riflesís accuracy but it does aid the rifleman when shooting multiable rounds in rapid fire, as the bullets wonít walk from a hot barrel that has been ďheat treatedĒ or Cryo treated - barrel life might be improved by a couple hundred rounds relative to itís ďbest accuracyĒ, normally associated with custom match barrels that are usually heat treated.

JB Bore Paste does a good job if used long enough - like maybe a year or two.

Hammer forged barrels are smoother and better over-all quality.

Button rifling is very good, but not like hammer forged.

like some others ive been there and done that and saw very little if any gain from it. It its a shooter it usually will be right out of the box. If it isn't its going to take probably more then barrel break in or even tubs lapping bullets (that I used to be a big fan of myself) to change much. Id say clean it take it out and start shooting groups. Clean it after ever session at the range to get the copper out and when you get done with load development and find the load you like the best go back and try it one last time. If its good its good. If a gun starts out as a 2moa gun your not going to make it into a 1/2 moa gun lapping or breaking it in.

well I shot one and cleaned, after 8 shots copper fouling was a lot less did this 10 times .then the next day I shot 3 rounds and cleaned hardly any copper fouling then shot 3 rounds 4 times waiting for barrel to cool down a little between each 3 rounds gave it a good cleaning copper fouling was not much more than after the first 3 rounds shot .i'll do the same shooting 5 round strings and call it good .I wasn't trying to shoot for accuracy didn't hang up a target but was shooting at a 9" steel plate and small rocks from 100 yards and hit the plate everytime and 5 out of 6 rocks [3''-5''rocks]
