Cut Vs Button Rifling

9/23/2017

Cut rifling is using the exact same cutter in order to impart the spiraling grooves present within rifling.
Button rifling is utilizing multiple cutters cutting their own individual rifling grooves as it is either pulled or pushed through.

Both types of rifling can produce match winning barrels, however the market currently favors cut rifled barrels. We believe this to be for multiple reasons. Button rifling requires an additional step in order to take out the stress out of the barrel from the button being pushed through. This is normally done by heating the barrel and can cause differences in hardness throughout the barrel if not done correctly. Another reason is the that the button has to be machined to higher tolerances in order to create rifling in which each groove matches each other. When using the cut method it is much easier to make a single cutter vs the multiple.

We believe that substantially more effort is required in order to create a button rifle that is able to compete with cut rifled barrels because of the additional factors that must be taken care of in button process.

Vortex Razor Gen II 4.5-27x56 Review

7/2/2016

1 Comment

The vortex gen II scope is one of, if not the most popular scope for precision rifles currently here in 2016. We recently got our hands on two of them and have been running one on our custom 700.
First reaction
My initial reaction to this scope is that its heavy! at 48.5oz you feel it. It is by far the heaviest scope I have had on a gun.
Optical Quality
Clarity wise the scope is excellent. At over 700 yards you can clearly see grass and make out objects that you would be unable with lower tier optics. In comparison to my Bushnell DMR, the scope offers significantly better clarity at ranges beyond 300 yards.
Reticle
The ebr-2c reticle gives me all the features I want out of a tactical scope, without getting to busy. The reticle is clearly visible throughout the power ranges without washing out in the background.
Turrets
The vortex turrets offer rapid adjustment by having 10mils per rotation. Each .1 mil of adjustment can be felt without any excess focus. A complaint I have with the turrets are with the locking feature. It is quite difficult to pull up on the turrets to unlock them. With it being equally difficult to find the right spot to push down to lock the turret.
Tracking
The turret after doing a standard tracking test passes with flying colors. After doing a full rotation from 0 and back, there was no shift in impact. the shots tracked equivalent to their amounts. .5mils were .5 mils.
Illumination
I am not the biggest fan of illumination, it is my opinion that it adds unneeded cost to optics. However vortex implemented illumination that adds to the usability to the scope, while also not getting in the way. The illumination control fits into the parallax adjustment knob and does not add excess bulk. I still would prefer a cheaper liter scope without illumination in the end.
Finish
The grey finish is even and appears very high quality. When compared to other manufacturers the finish on the razor is quite robust. The scope has yet to have any ring marks after the three rifles i have mounted it on.

Custom Rifles and What they Have to offer.

Custom Rifles allow people to obtain the exact performance they have been looking for. People can have builds that perform bench rest accurate, or they can create an ultralight hunting build that they can take to the mountains. It is up to the user to choose. To give a baseline for comparison a Remington 700 off the shelf vs a 700 action built up by PRC.
Stocks
Off the shelf
The off the shelf 700 will most likely come with your standard Remington stock. These stocks can expand and contract with different climates. This will cause your zero to change enough to miss that vital shot. In addition the Recoil lug sits into a cut out that is not properly fitted. In many cases we have seen factory rifles recoil off the receiver screw rather than the lug. While these screws can withstand this recoil it will put inconsistent torque on the receiver reducing the accuracy the rifle is capable of.
PRC Built
The stocks PRC puts their 700 action in are made out of rigid fiberglass and are filled with epoxy. These stiff materials result in minimal to no zero shift due to the climate's effect on the stock. In addition, PRC will add bedding compound to recoil lug,contact points, and the chamber area in order for consistent placement of the receiver.
Barrels
Off the shelf
Standard Remington barrels are button rifled and are built within a certain tolerance; buttons that are used can be within varying degrees of sharpness. This will translate into barrels that have a tendency to like specific brands of ammo or a specific load type.
PRC Built
When picking a barrel we choose proof research barrels. These barrels are cut rifled. Meaning they are cut one groove at a time at 1/1000" per cut. Proofs barrels are held to a very high tolerance and their barrels are consistent throughout.
Actions
Off the shelf
Remington actions can have varying tolerances. The receiver face, lug abutments, lugs, and recoil are not all square. The lugs can sometimes have less than 60% contact on the abutments. The barrel threads on a 700 will be slightly off center meaning the barrel chamber will not be lined up with the receiver body. This will further reduce accuracy.
PRC Built
We will take these Remington 700 actions and square up all these surfaces. Our lugs will not leave our shop until over 95% contact is achieved. The barrel threads are re-cut to line up within 1 / 10,000 of center line of the bore.
Overview
Even with all the accuracy set backs, off the shelf remington rifles are known to be accurate shooters. However, when we take away all the set backs you can easily imagine the end result. The rifles PRC put out are guaranteed to be 3 shot 3/4 MOA with groups hovering under half MOA or better.
