Sunday GunDay: For Xmas — Red X-Max Rifle from South Africa

Proud owner Dirk L. says: “This is my first build — never thought it would be a .308!”

Here’s a handsome F-TR rifle with a beautiful red stock that suits the holiday season. This ruby red beauty was a recent addition to the long-running Pride and Joy Rifle thread in our Shooters’ Forum. The rifle belongs to Forum member Dirk L. (aka “Pinkes”) who hails from South Africa. This is a .308 Win, with 30″ Bartlein barrel, and X-Max action. The stock is a custom composite with carbon fiber for strength and lightness. And yes this rifle shoots as good as it looks. Check out the impressive 5-shot groups below…

X-Max for Xmas — Impressive Metal-work
Along with that beautiful red stock, this F-TR rig has some very cool features, including a South African-crafted X-Max Action. The action designer Piet Welgemoed explains: “The X-Max action body is 17-4PH stainless steel pre-hardened to 44° Rockwell. Bolt and handle are one-piece stainless steel, nitrated to 55° Rockwell 0.2mm deep. Bolt is also fluted. Inside is the firing pin with washers (see below). The washer cuts the lock-time almost by half and also weighs less. The bolt-knob and bolt shroud are CNC aluminum. The action has very tight tolerances.” The complete action with +20 MOA rail and trigger weighs 1.475 kg (3.25 lbs).” Owner Dirk notes that the competition trigger, set at 3.0 ounces, is also Welgemoed’s design.

Wicked Accuracy with Bartlein Barrel, Varget, and 220gr SMKs
This gun has already proven to be a great shooter. Below are two FIVE-shot groups at 100 meters. The group on the left is in the low threes, with three of five shots essentially in one hole. Dirk loads Lapua .308 Palma brass and #2231 200gr Sierra Matchkings, seated 20 thousandths off the lands. The Varget powder and CCI primers drives the 200gr SMKs at 2620 fps.

Bullet: New 200gr SMK #2231 | Seating: 0.020″ Off | Velocity: 2620fps

Composite Stock — One of Three by Renier Mostert
And what about that beautiful red stock? The rifle’s owner told us: “This was one of three similar stocks built as a test run by Renier Mostert, a professional composite stock builder and former benchrest shooter from Pretoria, South Africa. Renier was approached by three friends, who were all looking for decent, custom-built FTR composite stocks. There were a number of stocks available to them (mostly imported), but [those] were either made of wood or aluminum. The requirements for the composite stock build was very specific. Aluminum V-Blocks for the actions were required. The stocks had to be light enough to carry some beefy barrels and optics without compromising rigidity and still be within the F-TR weight limit. The three friends supplied Renier with an imported wooden stock as their shape of choice. Although the shape was quite straight-forward, Renier made a few dimensional changes to features which were not symmetrically correct on the sample, and then built a mold from it.”

Renier uses several methods to craft composite stocks for various disciplines: F-Class, benchrest, competition rimfire, hunting, and tactical. For this build he chose to build a shell constructed of a well-planned mix of woven fiberglass cloth and bi-directionally woven carbon fiber with aerospace quality epoxy resin to reduce weight in some areas and increase stiffness in other areas. He used a wet lay-up process where the two halves gets laid up and joined together while still wet to form a complete, continuous shell. The closed mold gets cured under pressure in an oven for several hours at very specific temperatures. After curing, the shell is filled with a high-tech mix of lightweight filler and epoxy resin. The composition of the mix varies in different areas of the stock to facilitate more strength or reduced weight where applicable.

After the initial build, the aluminum hardware was installed. An adjustable cheek piece, Anschutz rail, and adjustable recoil pad mechanism were installed. The stocks were inletted by Renier, while the final fitting and bedding procedures were left for each customer’s gunsmith to complete. The stocks were light enough for the rifles to comfortably be within the F-TR weight limit. A barrel tuner was mounted on one of the rifles, and the rifle still made the F-TR Class weight limit, 8.25 kg (including bipod). The bipod shown in photos in the SEB Joy-Pod.

Paint — Candy Apple Red over Metallic Silver Base
After final gunsmithing, the stocks were returned to Renier Mostert for custom painting. The rifle featured in this article was done in Candy-Apple Red paint from DNA Paints (an Australian company). To get the desired effect, a metallic silver base coat was used, enhanced with a modest amount of medium coarse glitter, followed with multiple layers of candy until the correct shade was achieved. A high-quality automotive clear coat was used to finish off the paintwork.
