Most Savage barrels, barrel nuts, and actions are threaded 1.055"-20. In 2001 Savage began using a larger thread size 1-1/16"-20 for Winchester Short Magnum (WSM) calibers. This larger thread size has also been used on other magnum calibers and is often referred to as the "Large Shank" thread. Before purchasing a barrel or barrel nut, please measure the existing threads with a caliper.
Pre-1999 non-magnum and magnum caliber rifles have a bolt head that utilizes a large firing pin body diameter (nominal diameter is .150"), termed "large hole bolt head." These rifles may also have a tab in the bolt body that mates with the bolt head.
Post-1999 rifles use a small firing pin body diameter (nominal diameter is .100") in all rifles, both magnum and non-magnum. Important: This was a running production change. The large diameter firing pin components where used to build rifles until supplies where exhausted. The rifles built during the period 1999 through late 2001 will be found with both sizes, with the exception of the controlled round feed short magnums which will be small diameter only. The only way to confirm which components a transitional period rifle may have is to dismantle the bolt and measure the firing pin shank where it goes through the bolt head retaining pin.
To convert a bolt that now has an older large hole bolt head to the later small hole bolt head, it will be necessary to replace the existing parts with a small body firing pin, bolt head retaining pin and small hole bolt head. The replacement bolt heads are available in push feed and controlled feed configurations. All controlled feed rifles have the later small pin bolt head. If the rifle´s bolt has a slot that allows an action-mounted ejector to protrude into the bolt face to eject the cartridge case, then the rifle is controlled feed. If the rifle´s bolt face has a spring-loaded ejector in it, then the rifle is push feed. All short magnums are typically controlled feed. The exception is pre-2000 rifles in the Remington Ultra Magnum calibers, which may be push feed.
Replacement push feed bolt heads do not include the ejector, ejector spring, ejector retaining pin, extractor, extractor spring or extractor detent ball. Replacement controlled feed bolt heads do not include the extractor, extractor spring or extractor detent ball.
Replacement push feed bolt assemblies are complete except for the following parts which must be ordered separately: ejector, ejector spring, ejector retaining pin.
Replacement controlled feed bolt assemblies are complete except for the following parts which must be ordered separately: extractor, extractor spring, extractor detent ball.
Later-style small hole bolt heads do not have a milled recessed area for the older bolts that had a tab in the bolt body. If the rifle had a bolt with this tab, the tab will need to be removed to accept the later-style bolt head. The tab can be ground away with a Dremel or similar tool or filed off.
When fitting a bolt head, sufficient bolt baffle washers should be inserted in the bolt assembly to insure that the fit of the bolt head and bolt baffle is snug to the bolt body proper. This insures that the bolt head is fully supported by the bolt body. Otherwise, the bolt head retaining pin is supporting the bolt head and premature failure of the bolt head retaining pin will result.
The new AccuTrigger utilizes a receiver with milling cuts specific to this trigger group application. Savage rifles that are currently produced with the Savage AccuTrigger will not accept aftermarket triggers. These rifles are 2003 and later Varmint and Law Enforcement models. The AccuTrigger can not be retrofitted to earlier Model 110 and 10 rifles. Rifles produced without the AccuTrigger will accept aftermarket replacement triggers.
Savage 2003 and later rifles produced with the AccuTrigger, which are the Varmint and Law Enforcement models, have undergone a change in the receiver ring contours. These rifles use the same base for both the front and rear positions. For example, the rifle would require two Weaver #46 bases (product numbers 243-128 in gloss, 331-779 in matte or 111-424 in silver).
Important Note: This is a running production change, which will ultimately see all 110 and 10 series rifles using the new symmetrical front and rear receiver ring contour.
Savage used a few different action lengths over the years, especially when it comes to short actions. The distance between the action screws are:
Measuring the distance between the action screws will prevent purchasing the wrong stock.
