BARREL BREAK-IN PROCEDURE

Congratulations if you have just purchased from ZTOL Precision Barrels. We take extreme pride in our craftsmanship so please follow our break-in procedure.

Step 1 – items needed for Break-in

Bore guide

Quality-cleaning rod

.22 cal fleece or cloth patches

.223/5.56 Nylon or brass rifle bore brush

A Quality bore solvent (Montana x-treme, Remington 40x solvent, Hoppes, Butches, JB’s, Uncle Nicks, Boretech, CLP Break Free .)

Quality oil (Rem-oil, Militec, Sweet Shooter)

Step 2

In a safe manner, shoot the first 20-30 rounds thru the barrel cleaning between each round fired, using a bore brush first, 3-5 passes from the chamber end of the barrel and using a bore guide if possible. Then you should run a damp patch with bore solvent thru 2-3 passes let it sit few a minute or two. Then run fresh patches thru, change every pass until the patch comes thru clean (without residue, REPEAT IF necessary). Last passes with an oily patch 2-3 times.

Step 3

Never exceed 2 consecutive rounds without cleaning until after you have shot 65-75 rounds minimum thru the barrel. Bore brush and patch procedure

from (step 2).

Never exceed 5-8 rounds until after you have reached 100-125 rounds. After about 50 rounds the barrel will commonly start to group shots, sometimes earlier sometimes later. Regardless once you have exceeded 150-200 rounds the barrel is ready for long range shooting and should still be cleaned regularly. Expect the group size to continue dropping in diameter as the barrel breaks in more and more.

Following the proper break in procedure for your barrel can be the difference of a 0.25”group up to 2” group size if not performed correctly.

Cost Justification

Is there a cost justification for buying a premium match grade rifle barrel?

We believe that if you are truly interested in competitive shooting success that a premium barrel is the only one to shoot. It very basic logic.

The question was “is there a cost justification?” Well, here is our iron logic.

If you were to buy a $400.00 AR 15 barrel and shoot is say…..6000 times before you swapped it out,

it would have cost about 7 cents a shot. Small money in the big picture.

Now what would the ammo have cost you?

Well a good match grade .223 ammo cost in the range of $0.60 cents to $1.00 per round.

That’s $4,000.00 to $6,000.00 total cost of ammo over the life of the barrel.

Add the price of the barrel to the ammo and you will have spent $4,400 to $6,400.00 over its life.

An average cost of $5,400.00 or 90 cents a shot.

Now comes the big question. What is the cost of a cheap barrel?

The cost of an inferior barrel is compounded by how many shots miss the target.

If the average cost of a $200.00 barrel is $5,200.00 total or 87 cents a shot.

But if you can’t consistently group your shots because of poor predictable performance……

YOU DON’T LEARN ANYTHING!!! That’s what competitive shooting is all about.

If you can’t learn to develop a proper and successful shooting technique you have not only wasted the 87 cents per shot but the time it takes you to improve.

Wouldn’t it only make sense to spend the extra few cents? Sense = cents?

ZTOL barrels group tighter and more consistent shots on target.

Our manufacturing and inspection teaches us that as well as our range testing.
