Our Prefit 1MOA accuracy guarantee is 3 rounds at 100 yards with quality ammo and a skilled shooter. Like anything X-Caliber makes, we stand behind it 100%. If you do not think your barrel can shoot 1MOA groups or less, we will have you ship it back. We will inspect the barrel. If the barrel fails, we will build you another barrel and ship it to you at no cost. If the barrel passes all test, it will be shipped back to you at your expense.

X-Caliber Barrel Break-In

Procedure Guide

 

When breaking in your new X-Caliber Barrel, you should perform appropriate fire and clean cycles to normalize the bore surface. Each fire and clean cycle consists of a certain number of rounds fired (one to five) followed by a cleaning procedure (see below for reference), to be completed a certain number of times (1-25). These vary depending on the type of steel of the barrel, bore/groove diameter, velocity and pressure of any given round, etc. This is to be used as a guide. Since our barrels are hand-lapped, each barrel may break in a little differently. Some barrels may require more or less shots or cycles to break in than what is listed here.

 

416R Stainless Steel: Fire One Round then Clean: Do this 5-10 times. Fire Three Times then Clean: Do this 1 time. Fire Five Times then Clean: Do this 1 time.

4140 Chrome Moly: Fire Once Round then Clean: Do this 5-25 times. Fire Three Times then Clean: Do this 2 times. Fire Five Times then Clean: Do this 1 time.

 

 Example: For a 416R Stainless Steel barrel, you would fire one round, then perform the cleaning steps outlined below a total of five to ten times (shoot 1 round & clean, done 5-10 times) before starting the three shot cycle where you would fire three rounds and then clean as outlined below, then proceed to fire five rounds then clean, completing the break-in procedure.

 

Each Firing Cycle (1 shot, 3 shot or 5 shot) should be followed by cleaning the bore (see steps below for reference):

 

1.)    Using a one-piece, coated cleaning rod with a properly sized bore brush (wet with your favorite non-foaming bore solvent), carefully clean the bore from the chamber end toward the muzzle (3-5 passes is usually sufficient). If you cannot clean from the chamber end, be sure to use a bore-guide so as not to damage the crown or muzzle end of the rifling. Let sit 30-60 seconds before moving on to the next step.

2.)    Push a dry patch down the bore. (2-3 times)

3.)    Put a few of drops of oil on a patch and push that down the bore so as to leave a thin film of oil inside the bore.

4.)    Begin a new cycle: Fire your next round or rounds in your next firing cycle and repeat cleaning as necessary.

  

It is recommended to keep a written tally of your current step within the process so if you get distracted you will know where you left off.

.270 Win Barrel for Rem 783 Rifle
Bought a stainless steel barrel to replace one on a Rem 783 after a squib load got stuck. Looks great and shoots better. The heavier barrel really takes the recoil on this gun. The stock 783 was fairly light and the recoil hurt me and my kid hated shooting it. Changing the barrel and adding a heavier stock, it’s now a joy to shoot. I will definitely get any other barrels I need from X-Caliber. Great product, great service. Thank you.

Remington 783 pre-fit in 7.62x39
I have wanted a 783 pre-fit barrel in 7.62x39 for a while, and couldn't find anyone currently chambering in this caliber t my specifications. Well, X-Caliber is the only that could, so I decided to place an order. I went with a 416R SS, 20" with 11* crown, in the Remington Magnum profile, chambered in 7.62x39, with a .308 groove diameter, as I planned to handload for this rifle exclusively with .308 projectiles.

The next afternoon, I received a phone call from X-Caliber stating that my .308" groove diameter was not doable do to SAAMI safety concerns, and because they didn't have the correct pilot for the 7.62x39 reamer they had. I was told they would do it, but could not in order to meet the 5 week lead time. I conceded that it wasn't doable and settled on the standard .310" groove diameter. Boy, am I glad I did.

The rifle arrived in three weeks if I remember correctly, and I proceeded to install it that following weekend. This was not my first 783 barrel swap, so this was standard fare for me. If you decide to do this same swap, use Clymer SAAMI spec go/no go gauges.

Let me say this. The barrel arrived in excellent shape and was above my expectations. The chambering engraving is a bit far back, and is almost completely hidden by the barrel nut, but for me this isn't an issue. For some it might be. The profile is spot on for a Remington 783 and fit like a glove, in the factory stock. The matte finish I ordered contrasts with the matte Remington finish perfectly. The first five rounds down the pipe were Winchester 123 gr FMJ brass, and they printed under an inch at 100 yards. I was using a Simmons 8 point 4-12x40 scope that is usable but not super clear. So, that's saying something. I have done no break-in procedure, and was able to get these kinds of groups. Even my 76 year old neighbor shot this rifle and was impressed.

My handloads are 125 gr Sierra Pro Hunter .311" projectiles, and I was able to tune this round to 2408 fps, once-fired Winchester brass, printing .865" at 100 yards. I couldn't be happier with this barrel. It truly exceeded any expectations I had, and I'm very happy with my purchase. I'm seriously thinking of barreling a .223 783 in .204 Ruger with an X-Caliber barrel. Yes they're that good folks. This is my new deer rifle from now on. Don't hesitate to order a barrel from this great company. You'll not be disappointed

Model 783 7mm Remington Magnum
26” 1:8 5R in 416 stainless. Went to my shop and installed the barrel, and after break in there is little to no copper fouling. With very little work the results at 100 and 300 are outstanding. 175gr ELD-X loaded over RL-25 at 3003 fps average with no pressure indications. 5 shot group at 100 yards was .32”, and 3 rounds at 300 was a hair under .5”. Veteran friendly business, top notch workmanship, unmatched quality, EXCELLENT hand lapped bore that gives extreme accuracy. I couldn’t ask for more. Well done gentlemen, there are more X-Caliber barrels in my future.

I just ordered my 5th barrel from X-Caliber
First barrel was for my 783 in 243 win. I was very impressed with the quality and fitment. It was really nice to not have to wait for a gunsmith to chamber the barrel.
1000 rounds later and the bore scope shows it might go another 1k. shooting 105's at 3150 fps and still shooting sub 1/4". so I bought a second barrel for it when this one is done I'll just screw the new one on.
The 3rd barrel I ordered was for a defiance action chambered in 284. That one shoots in the 2's as well.
The 4th barrel was for a 6.5 Creedmoor. Same performance!
The barrels break in quickly and are easy to clean. I was worried about the free bore on the 284 but the Berger 184's work great in that chambering.
So needless to say I just ordered my 5th barrel as a back up for the 284 win. 29 inches straight blank and this time I opted for the Cryogenics.
Thank you X-Caliber.
