This neck and shoulder geometry design was no accident.
Pro2A said: Trijicon's new RMRcc features the durability and reliable controls that have made the RMR so successful, but its reduced dimensions make the “Concealed Carry” model better suited for the popular small-frame pistols designed for discreet carry and personal defense.
It’s worth noting that the .300 PRC is a necked-down .375 Ruger, its parent case.
During the Idaho visit, I had the opportunity to shoot the cartridge out to 2,349 yards. I had to see first-hand just how the .300 PRC performed at really long distances, so I had Mile High Shooting Accessories (milehighshooting.com) chamber a barrel in it for my Accuracy International AXMC. We’ve been at war for 17 years and the handful of times that kind of range was necessary, snipers would typically walk rounds in on target until they got lucky. A perfectly designed case would have the top of the bullet’s boattail sitting right at the case’s neck and shoulder junction.
Used an old A5 stock, had the long DBM installed to run up to 3.700 c.o.a.l.
Just a year or so ago I wrote that the 30 Nosler was arguably the single best-designed .30-caliber magnum in existence. One Browning Place Rifles & Optics Editor Tom Beckstrand discuss the Hornady rifle line of Critical Defense... Give a Gift
Hornady .300 PRC (left) and 30 Nosler 30 Nosler vs. Hornady .300 PRC. I built a .30-375R wildcat in 2009, but never finished it.
I built mine with a Bartlein 1:8 twist, in a trued 700 action. So now, I want to finish what I started.
As a matter of mirror-image fact, the two cases are extremely similar. This means velocity should be high, accuracy exceptional, and all with a barrel life similar to a .300 WM since the .300 PRC uses a pinch more powder. While the dimensions of these cartridges are all pretty similar, the throat length and throat diameter of the .300 PRC are tighter than any of the wildcats. You must log in or register to reply here.
When a bullet sits inside the powder column, it can be bent or pushed off-axis, making it unstable in flight or forcing the bullet to yaw prior to engaging the rifling. Just about every .30-caliber magnum puts a lot of bullet in the case. The X-Bolt is free-floated by bedding the front and rear of the action for stability and to help maintain barrel to stock spacing for consistent accuracy. This is why the .300 PRC combines both a tight freebore while still refusing to put the bullet inside the powder column. Building a 2,000-Yard Rifle in the New 300 PRC. When a shooter jumps to the larger .588-inch bolt face — as used in the .300 Norma — actions and other components become more expensive. Prev. The X-Bolt's new three-lever Feather Trigger provides a clean, crisp pull with no take-up or creep and minimal overtravel.
This means a .308 bullet, when chambered, is going to sit inside a hole that is only .0008-inch larger than the bullet. As a former sniper, I would argue that the expectation is unrealistic and any fractional performance gains achieved in its pursuit are not going to be worth the effort or expense. However, hits were still manageable — even with a slow and changing wind.
In short, it gets slightly smashed into a new shape.
That’s an increase of 875 percent in freebore clearance, which illustrates the stark contrast between a precise cartridge and one that throws the proverbial hot dog down a hallway. The .300 PRC was designed to specifically avoid this problem. Taking advantage of that knowledge base is a marvelous strategic idea, and it makes me want to stand at attention just thinking about it.
The time at FTW allowed me and two friends to shoot at a 32-inch circular steel target at 1,600 yards.
It appears that you are accessing the Browning Website from outside North America. By John B. Folks, you won’t find a more shooter- and rifle-friendly, .30-caliber magnum than this one. Right down the list, it’s got a standard bolt face, a 3.70 cartridge overall length that allows seating the bullet way out of the case, a case overall length of 2.580 that leaves 1.120 inches of head height to a fit longer bullets while meeting the COAL requirements. Read more... Browning Go. Would you like to visit Browning International? The length of the.300 PRC is held to 3.7 inches maximum overall length, but it has a neck/shoulder junction closer to the case head than the.300 WM, even though the.300 PRC is about one-third of an inch longer overall.

Settled on 26". Next, we pit subsonic rivals against each other before stretching the legs of this CQB round out to 600 yards from a short 9-inch barrel.
When I first learned Hornady was coming out with a long-action, .30-caliber magnum cartridge, the question that first came to mind was, Why?
Today, I have to give that nod to the .300 PRC. I took that rifle to the FTW Ranch (ftwsaam.com) in Texas for evaluation and then again to a friend’s training facility in Idaho for a few more days of study.
First Prev 2 of 3 Go to page. The issues with those cartridges were that the host guns are simply huge and the ammunition is large and heavy. Snow. Bullets get pushed from the rear when a cartridge fires, so it’s easy for them to twist or yaw in the chamber prior to engaging the rifling. Should a bullet get crooked in the chamber before it hits the rifling, the bullet’s center of gravity gets forcibly moved when the bullet finally engages the rifling. It weighs about 17-18 pounds. For this shoot, Pro Tom Beckstrand, former U.S. Army Special Operations officer and sniper team leader, faces off against Guns & Ammo TV cameraman Ben LaLonde in a challenge that highlights the differences between these two cartridges. To add, we have a firearms industry that’s home to a handful of brilliant minds that know how to design and manufacture the tools necessary for extreme performance. I couldn’t decide what length so I just did 27.5 inch. Thanks Venatic that's the stuff I have been searching for. Under these conditions, SOCOM feels the best thing we can offer to protect our servicemen is to take a step back and put some distance between our enemy and us.

The solution they presented, given the parameters outlined by SOCOM, was the .300 PRC, which is similar to other .30-caliber wildcats like Dave Tooley’s .30 Boo Boo, the .300 Accuracy International (AI) and the .30-375 Ruger. This neck and shoulder geometry design was no accident.
Used at the bench, on the ground, or with-in 500 yards of the truck. That was my opinion before listening to a member of SOCOM involved in the requirement and hearing about the testing done for it. The results are spectacular. Given the longer 3.7-inch length, which still fits easily in AICS-pattern detachable-box magazines and most internal magazines, the .300 PRC puts as much powder behind a VLD bullet as possible while still keeping the bullet out of the case. No sniper moves very far or very fast on the battlefield with an oversized rifle and enough ammo to feed it. The bolt unlock button works in conjunction with the top-tang safety to provide an added measure of safety during checking and unloading of the chamber.
Sounds like ours will be very close. The freebore diameter is held to a snug .3088-inch. This means you can safely chamber and fire .300 PRC ammunition in most .30-375 wildcats. The .300 WM suffers from this phenomenon the most. The freebore diameter on a .300 WM is a minimum .315-inch, as per SAAMI specs. That distance is asking a lot of any .30-caliber offering, and I thought it would be impossible with factory ammunition. Accuracy International developed their .300 AI cartridge in 2009 when SOCOM had some aggressive accuracy requirements of 1,500 meters for a long-range, sniper-rifle solicitation. A recessed muzzle crown helps protect the rifling from damage. This is essential for consistent long-range performance. The people asked and Trijicon answered. Hornady wanted to use a case head size of .532-inch to allow most long-action rifles to easily chamber this cartridge. For background, Tooley is a champion benchrest shooter who frequently competes out to 1,000 yards. Surely, those cover all the demands from a .30- caliber.
Now, it is quite common to face near-peer elements in some parts of the world.
The .375 H&H is more than a century old, but still a popular and versatile choice for hunting big and dangerous game. The only questions are: “What is going to get shot at you? More Guns. With case head size selected, Hornady set about designing the rest of the cartridge for precision. In this segment of “At The Range,” Handgunning Editor Jeremy Stafford and contributor Patrick Sweeney compare the visibility of red and green lasers in outdoor, sunny conditions.
Since there’s no way to predict what the new shape will be, accuracy is erratic when this happens. Latest.
Hope that helps. Updated: January 18, 2019. Maybe you guys in this thread can help me a little.
This rifle—designed by OL's shooting editor and built by the Remington Custom Shop—Is accurate to 1 mile and beyond. The .300 PRC is the only .30-caliber magnum to be designed around this principle. This recoil pad has proprietary construction and material to promote a directional deflection of recoil forces, pulling the stock comb away from your face to reduce felt recoil and muzzle climb.
Readily available factory ammunition pushes Hornady’s 225-grain ELD-M at 2,880 feet per second, keeping it supersonic to almost 2,000 yards at the 3,000-foot elevation I tested.

The length of the .300 PRC is held to 3.7 inches maximum overall length, but it has a neck/shoulder junction closer to the case head than the .300 WM, even though the .300 PRC is about one-third of an inch longer overall.
Initial testing and barrel break in with 225 ELDX over 75 gr. I do a mix of hunting and for fun target shooting with this 300 PRC, I went with a 26” 1-9.5 #4 Fluted Benchmark. The 6.5 Creedmoor is a newer and popular cartridge that transcends long-range precision rifle shooting and hunting big game. This keeps the bullet’s bearing surface above the joint, which simplifies reloading procedures, but also keeps the bullet out of the powder column. No nation on earth produces rifleman like America.
