(1) Premium Grade Stainless Steel. The body of every action is machined from 17-4 stainless steel. This is a tougher, more corrosion resistant material compared to 4000-series alloy often used on firearms. The surface of the action is hardened to 42-43 RC. The bolt body uses even tougher 9310 steel, surface hardened to over 60 RC. Tight benchrest tolerances. Decades of experience in the benchrest circuit have shown that absolute concentricity of the bolt and the action body around the axis defined by the bore line of the barrel is paramount to precision shooting. Each McMillan action is CNC machined from a centerless ground billet blank, not a forging. The face of the action is absolutely perpendicular to the axis of the bolt. Tolerances on general metalwork are held to within 0.005″. Critical parts are held to 0.0005″ tolerances.
(2) Fluted Bolt Aids Reliability. Flutes sweep mud and grit away, helping to keep the action operating smoothly in harsh environments and reduces overall weight.
(3) Accepts Remington-Style Trigger.
(4) Even the underside of a McMillan Action is a “work of art”. In a production action, this area is finished poorly with burrs and tool marks to save costs. In contrast, every component of a McMillan G30 action shows precision engineering and attention to detail throughout, whether the area is hidden or exposed.
(5) Recessed Bolt Face for strength. The bolt face, the barrel shank and the action all surround the cartridge head to add strength in this critical area during ignition. Dual Fail-Safe Ejector. The McMillan G30 push feed action uses a Remington-style plunger ejector, plus a secondary backup spring-loaded mechanical ejector that lifts up as the bolt body passes over it at the end of the stroke. Bolts are fitted to receiver by hand, filing the camming angles and lapping the locking lugs.
Bolt Raceways Are Cut with Wire EDM. Electrical Discharge Machining produces tighter tolerances, no tool marks, and a smoother sliding bolt.
The McMillan push feed action uses a “Sako-style” claw extractor of our own design. This produces positive extraction and push-round feeding. Control round feed bolts use a unique extractor housed in the locking lug eliminating the need to cut an extractor slot in the barrel and also us to hold closer tolerances in the bolt to receiver fit. CRF are available on all cartridges except those with Rigby size .590 case head.
(6) No Tools Bolt Disassembly. The innovative G30 bolt disassembles easily without tools so you can clean the firing pin assembly.
Take the bolt in left hand, palm facing down, with the bolt toward your thumb. Place your left thumb on the bolt handle while gripping the bolt body. Grasp the cocking piece housing in your right hand and rotate away from you about 1/4 turn. Then remove the firing pin. To replace the firing pin, place the bolt in your left hand in the same manner, grab only the cocking piece housing, slide the firing pin in, rotating it slightly until it slides into the guide slot and forward portion of the cocking piece touches the bolt. Now press the cocking piece housing toward the bolt compressing the firing pin spring. Once the cocking piece housing is butted against the bolt body rotate the housing counter clockwise until the cocking piece slips into the locking detent. Simple, no tools firing pin removal.
While the firing pin is out notice there is very little grease on the spring. None is needed. The bolt and the internals are finished with NP3 patented electro less nickel impregnated with Teflon particles) which not only provides the very best in corrosion and wear resistance but also has a very high degree of lubricity so it eliminates the need for grease. We do use a little red gun oil on the firing pin body where it meats the bolt body.
Your rifle has a Schneider match grade stainless #5 fluted barrel will polygon rifling. Berger bullets are thin jacketed bullets which like to be seated on the lands. If you look at the bore you will notice that it does not have convention lands and grooves but rather flats. This adds velocity and does not engrave the bullets. With less jacket deformation the bullet actually flies truer. When we get you some ammo you should see a significant difference in the accuracy at 1000 yards. It has a Vias break.
The stock is basically a clone of the Sako Hunter, the most popular hunting stock in the history of McMillan Fiberglass stocks. The Monte Carlo with cheek piece, along with the palm swell, makes the stock extremely comfortable. The fact that it has some cast off allows you to mount the rifle and find the sweet spot in the scope without having to tilt your heard. It also has some cant or toe out, which allows the toe of the recoil pad to fit into the shoulder crease without having to cant the rifle. The Decelerator pad is the best all around recoil reducing pad on the market, bar none. I would never use anything else, though we do install Limb Savers and Kick-eez if a stock customer requests it. I would not build a rifle with either.
Bob Beck of EOL designed the chamber specifically to shoot the Berger 180 VLD and seat them on the lands. He actually built a load with a COAL that would allow us to feed them from our mag box and eject a loaded round. Then McMillan had a chamber reamer made to those specs. The nice thing is, it will shoot almost all factory 300 RUM ammo without any signs of pressure, so even though it was designed specifically for this load, a customer is not limited to our ammo alone.
Finally, it has a McMillan 6061T6 aluminum 20 MOA scope base rail with a steel locking pin that sits against the front of the ejection port with 8-40 scope base screws.
