Savage Prefits
The Savage Prefit barrel is a product that every major barrel manufacturer is producing for competent gunsmiths with skill levels ranging from the at home do-it-yourselfer up to your certified professional. If you are gun-savy and have a barrel vise, a Savage barrel nut wrench and the corresponding chambers’ Go gauge, you have everything you need to correctly change your Savage barrel. Savage pre fits come in 2 shank sizes; Standard (small) Shank / 1.058”-20, Large / 1.120”-20. Please be sure of your Savages’ shank size before placing order to ensure an easy order placement.
Please check our Frequently Asked Questions for our current lead times.
To be used with recoil lugs .300 or thinner.
*NOTE* Our Savage Large Shank Prefits use the standard OEM Savage action-thread length, which in some cases may be too short with some aftermarket Large Shank Barrel nuts, which may run about 3/16" longer than factory Savage barrel nuts and thus will not work with our prefits. Our Prefits only support barrel nuts that use the same thread-pitch and internal thread length (footprint) of Savage factory barrel nuts!
***THESE SAVAGE PREFIT BARRELS REQUIRE A BARREL NUT AND ARE ONLY COMPATIBLE WITH STANDARD FACTORY SAVAGE SMALL SHANK OR LARGE SHANK ACTION THREADS (1-1/16"x20TPI FOR SMALL SHANK OR 1-1/8"x20TPI FOR LARGE SHANK) AND RESPECTIVE SAVAGE BOLT-FACE GEOMETRIES & LUG GEOMETRIES: ANY DIMENSIONAL DEVIATIONS FROM ANY/ALL OF THOSE DESIGN ELEMENTS ON YOUR ACTION AND/OR BOLT-FACE WILL PREVENT PROPER FITMENT AND/OR HEADSPACING OF THIS PREFIT BARREL***
Small Shank size will fit with Aero Precision Solus Action.
Barrel nut required, not included.

Don't know which Savage shank size your rifle uses? It's always best to measure your shank size directly to determine whether it is Small/Standard (1.058") shank or Large (1.120") shank. For more information, see this reference.

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.
For more information about our 1MOA accuracy guarantee and the conditions that apply, please refer to our FAQ or Conditions Pages.

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.
