INTRODUCTION

The Ridgeline FFT is the latest model in Christensen’s Ridgeline series of rifles. The FFT stands for Flash Forged Technology, a new process used to produce its carbon fiber stocks. Christensen claims this new tech further reduces the rifle’s weight for the ultimate lightweight hunting rifle.

Being foremost a hunter, I am always interested in the latest new thing. And with Christensen being located here in my own state of Utah, I was even more excited to see them leading the way with new ideas. While I’m not sure if a lighter rifle will improve my shooting, at least I won’t be as fatigued when I come home empty-handed.

I have been hunting these Rocky Mountains for over a few decades, so I’d like to think this rifle was built for guys like me. As such, I was eager to see how it measured up to the quality customs and other carbon rifles I am used to. My initial thoughts on handling the Ridgeline FFT were that I would be quite pleased with the rifle.

RANGE TESTING

I’d anticipated receiving this rifle for some time, I’d even received some ammunition already for it thanks to the good folks at Hornady. Since the action of the Ridgeline is compatible with Remington 700 parts, I grabbed a Leupold scope base I had in my toolbox and tightened it down on the Burnt Bronze action.

For a rifle scope, I decided to install my US Optics TS20X. I had a set of 34mm rings that put the scope just the right height for me, so I adjusted it for proper eye relief and torqued it down properly.

I put a touch of lube on the contact points of the bolt body to slick it up and installed a bipod on the rifle before heading out. I prefer the solitude of the mountains over shooting ranges, so I dressed up for the cold and grabbed the rest of my stuff as I headed up the hills.

In my bag, I had a couple of boxes of ammunition from Hornady, both the Precision Hunter 175 ELDX load and the Match 180 ELDM. I also carried my Desert Tech DTSS suppressor to see how the rifle shot when suppressed and a Magnetospeed chronograph to measure velocity.

The first thing I wanted to get established was a good zero, so after setting my target at one hundred yards, I settled down on my shooting mat to get comfortable with the FFT.

I pushed three cartridges down into the magazine, which had plenty of room. It looked like you could seat the bullets really quite long and still have them fit and feed from the magazine. I ran the bolt forward to chamber the first round, closing the bolt into the battery as I peered through the scope.

I fired the first shot and two more to confirm impact; I was going to need to shift my impact about one MRAD right and up a touch. After doing so, I shot a couple of groups to see how the rifle performed, all while paying attention to the recoil impulse through the stock.

I would only shoot three shots and let the rifle sit for a few minutes. I didn’t really want to get it hot. Being a hunting rifle, I think it’s likely such a rifle would be carried a lot more than shot. After shooting a few groups, I paused to evaluate my findings.

I was surprised by how mild the recoil felt; surely, the muzzle brake was reducing a good portion of the impact. The accuracy was not spectacular, though I think it may need a minute to settle this bore down. I noticed that the three-shot groups would always have two together and the third one off just a bit.

I fired a few more rounds to finish off the two boxes, and I figured it would be good practice to see how the Ridgeline did on the open distances that these Rocky Mountains are famous for.

I picked a few targets, the first one at 530 yards opposite my canyon perch. After entering all the ballistic data into my Trasol Ballistic application, it came back with a firing solution which I dialed into the turret.

As I lay still in the snow, I looked at the snow stacked on top of my target. I held into the wind and pressed the trigger shoe till the shot broke. I could see a very significant impact on the target, knocking the snow off in a powdery cloud.

RELIABILITY

The Ridgeline FFT was very reliable at feeding and firing the PRC cartridges. I never experienced any issues other than the occasional magazine bind when you put them in poorly. The minimal controls of the rifle all worked fine, and I also noticed that the bolt lift that had seemed a little stiff back at home, didn’t seem to bother me from the shooting position.

ACCURACY

At first, I wasn’t particularly impressed with the rifle’s accuracy. I do think that shooting it more has helped; perhaps the bore needs a little break-in before it shoots its best. It did seem to prefer the Precision Hunter 175-grain ammunition over the 180-grain Match ammunition.

The Ridgeline does have an eight-twist barrel, which is the minimum for the 180-grain ELDM, so it’s possible that it could be on the verge of stability.

According to Christensen’s website, there is a 50-round barrel break-in process.

I was born and raised in the dry desert state of Utah, as such I am no stranger to the fine firearms manufacturers in this state. One of the more famous firearms companies comes from the beautiful little town of Gunnison Utah, Christensen Arms. I have known of the company for some time, but several years ago I was offered tour of their facility. Their famous carbon fiber is just part of the whole Christensen production, titanium, stainless and aerospace technology are all part of Christensen’s multi-faceted production facility. Many manufacturers, particularly those with higher price-points source their barrel blanks from well known barrel producers. Christensen cuts their own barrels, and wraps them in carbon fiber before mounting to their custom actions. They are then married them to a stock or chassis that also might be built from carbon fiber molded right there in the factory.
Things may have changed even more since my visit to the factory, but ever since then I have been wanting to try out one of these rifles. Today is finally my first chance, as I have in my possession a Christensen Ridgeline 300WSM.

The Ridgeline
The Ridgeline from Christensen is built from a stainless steel action, which shares many dimensions with the Remington 700 pattern. This allows users to utilize the large aftermarket support enjoyed by the 700 series. The action features additional cuts to reduce weight and enhance performance, and things like an enhanced bolt release make it superior to other designs. The Ridgeline comes from the factory with a Trigger Tech trigger, which are very well known for their quality and performance. The fluted bolt uses an M16 like extractor, and a plunger ejector. The threaded bolt handle comes with a petite bolt-knob which you can change out if you desire.

The carbon wrapped barrel on this rifle is chambered in the powerful 300 Winchester Short Magnum, a cartridge I am quite familiar with. The barrel is twenty-four inches long, and features a one-in-ten twist, and threaded 5/8-24 at the muzzle where you will find Christensen’s radially ported muzzle brake.
The stock for the rifle is a composite construction, which uses a pillar-bedded design to improve the accuracy and performance of the rifle. A comfortable recoil pad and sling-studs are of course standard.

In the hands
As I lifted the Ridgeline from its box, the definitive feature of these rifles was immediately evident. This thing is quite light! A rifle this size feels impressively light at under seven pounds, very desirable for a hunting rifle like this. I ran the bolt a few times, and squeezed the trigger to make sure everything looked good. And then It was time to get thing thing ready for the field.
I installed a Nightforce 30 MOA scope base, that made mounting my scope easy. I used one of my favorite scopes, and one that I frequently switch back and forth between a great many rifles. The TS20X from US Optics is an excellent choice for a long range hunting rifle like this. The 2.5X is useful for an up close encounter should you be a stealthy sneaker, and if you get a shot that is way out there, 20X is plenty for making those long shots. I mounted up the scope with a set of 34mm rings, I would have preferred a bit lower set to better fit me but these would do for now.
I also attached a Harris bipod to the front of the stock, a good bipod almost goes without saying on a long-range hunting rifle. The three-round magazine looked rather vacant without anything to fill it, so it was time to find some ammo. As I mentioned I am no stranger to the 300WSM, I’ve probably shot several thousand rounds of it over the many years I’ve spent chasing Utah’s big game, and preparing for the hunt. So I had everything on hand to make my own ammunition for the Ridgeline, but I also wanted to shoot some factory produced ammunition for those that want to know. I had on hand some Federal Fusion 300WSM loaded with 180 grain bullets, a perfect representation of what a Rocky Mountain hunter would want to use for elk or deer. Besides that I loaded up some Norma Brass with my favorite load featuring a Sierra 190 grain Match King, a load responsible for dropping a dozen or so big game animals from my first antelope at 880 yards to big cow elk at 400 yards.

Let’s Hunt
The Ridgeline is a hunting rifle, everything about it is optimized for a hard-core big game hunter. I imagine it in the frigid cold hands of a sheep hunter in the Northwest Territories, or over the shoulder of a backcountry elk hunter leading mules to a distant basecamp. I wanted to see how it would do in exactly that situation, so I took it deep into the high Rocky Mountains. After zeroing the rifle at 100 yards, I wanted to see how accurate the rifle would shoot considering Christensen rifles come with a sub-MOA accuracy guarantee. The Federal Fusion 180’s shot a sub-MOA three shot group, but when I fired two more it opened up what I would call considerably. I assume this is likely to do with the barrel heating up from the magnum cartridges and pressure.

I installed a suppressor on the rifle, in my experience most rifles seem to shoot better when suppressed. And besides that, it’s just better. The Desert Tech Sound Suppressor (DTSS) was a perfect match for the lightweight Ridgeline, its titanium construction doesn’t add much to the rifle. And it easily handles the pressure of the 300WSM reducing the noise to a reasonable raucous.
I then stretched out the rifle to some more realistic distances, this open country allows for long shots. It isn’t uncommon to find big game from a mile or two away, and stalking into a closer distance. Its also not uncommon for the terrain to keep you from getting within a certain distance, so being able to make shots at long-range is helpful.
Making hits with this rifle at five and seven hundred yards was not difficult, but I again noticed that after a few shots my hits began to wander despite the nonexistent wind. Continue Reading Here…
