If you look at that 5-round group you might think it was shot with a 6 PPC or maybe a 6mmBR. But no, this was done with heavy 180gr Berger Hybrid bullets and the .284 Shehane, an improved version of the .284 Winchester. In fact, this impressive sub-quarter MOA group was shot while fire-forming with a very well-worn barrel! Gun builder Ryan Pierce of Piercision Rifles explains:
Here’s a 5-shot 0.191″ group at 100 yards with my .284 Shehane fire-forming loads. This barrel has 2200 rounds through it. It had 2000 as a straight .284 Win and then I set it back to .284 Shehane to form brass with. This was the first five rounds through it after I cleaned it after the last match. [The load was] 180 Hybrids with 54.0 grains of H4831 SC.
Ya, I figured why not I had some old barrels laying around so I just chopped 2″ off the back and 1″ off the front and chambered it up as a Shehane. Had 1000 pieces to fireform and didn’t want to do all that on a brand new barrel.
My fireform loads are going 2765 FPS. I have a 29″ barrel also though since it’s a setback. Once you get it formed I would push it faster than that or I wouldn’t even bother with the Shehane. My old straight .284 load at 2890 fps had ES spread in single digits for 10 shots. I figured if I get it up to 2935-2950 fps that will be a point or two saved in a several day match.
Our friend Erik Cortina notes that the .284 Shehane has a velocity edge over the straight .284 Win because it holds more powder: “The Shehane has more capacity than the .284 Winchester. Ryan is using 54.0 grains simply as a fire-forming load. Typical load for a Shehane is around 57.0 grains of Hodgdon H4831 SC.” By blowing the sidewalls out 0.010″, the .284 Shehane picks up about 3.3 grains of extra case capacity. That enhancement makes a BIG difference. The extra boiler room is enough to drive the 180s at 2900-2950 fps with H4831sc, with long barrels.
Forum member Jim Hardy has shot the .284 with great success. He tells us: “In my humble opinion, the .284 Shehane is the best balanced long-range round there is — bar none. Here is why:
You have to shoot a 30 Cal Magnum with a 240gr bullet to equal the performance of most 7mm chamberings with the 180 Berger VLD. With the .284 Shehane, you have a .308 bolt face, medium action, and Lapua brass. You use less powder than the 7 mags, and have great accuracy and ballistics even while fire-forming. The .284 Shehane shoots inside the 6.5 AND the straight .284, the .300 WSM, and the .300 Win Mag with less recoil. What is not to love about the 284 Shehane? It is a no-brainer for long range — F-Class or Prone or 1000-yard Benchrest.”
Scotland’s Grant Taylor. who used the .284 Shehane to finish third at the 2009 F-Class Worlds in England says the .284 Shehane is “very accurate with superb vertical spreads at 1000 yards. [This] caliber… has awesome accuracy. I’m getting 2930-2950 fps with spreads in the 3-5 fps range. I use Hodgdon H4831sc powder, CCI BR2 primers, and pointed 180gr Bergers.”

Here is something shiny and new for the guy who has to have the latest hardware. Ryan Pierce of “PiercisionRifles.com makes very effective muzzle brakes (aka “Muscle Brakes) that have a clever “self-timing” feature, that allows them to be fitted to multiple rifle barrels. Most of Ryan’s Muscle Brakes are crafted from steel, but he just introduced a slick 5-Port Self-Timing Titanium Brake. Ryan says the self-timing feature of this design allows the buyer to use the same brake on all rifles with the same thread pitch on the muzzle. Check it out:
Ryan reports: “Got the new TITANIUM self-timing 5-port ‘Muscle’ brake spun up on a 300 Norma improved I chambered this morning. The barrel and brake weighs 3.0 pounds total. At just 3.5 ounces, the titanium brake is 3 ounces lighter than the steel version. The Titanium Muscle brake is available in 5/8×24 and 3/4×24 threads. I have some ready to ship in 3/4×24 threads. I’ll have another batch ready to ship in a week or so in 5/8×24 threads.”
Who needs a Titanium brake? Well if you’re putting together a high-tech ultralight hunting rig, this is a nice finishing touch. When shooting off-hand, less weight on the end of the barrel really makes a difference. And if you’ve gone to the expense of fitting a lightweight carbon fiber-wrapped barrel, it may make sense to finish it off with an ultralight titanium brake.
How well does it work? Ryan says with this brake on his 10-lb .300 Norma Improved rifle he can see bullet impacts at 400 yards. That’s with 230-grain bullets launched at 3000+ FPS.
NOTE: Currently these brakes are sold in a 5-port version only. Ryan offers 3-port brakes in steel, but says the weight savings would be only 1 ounce with a Titanium 3-port.

A couple seasons back we published our comprehensive 6.5×47 Lapua Cartridge Guide, researched by the 6.5 Guys. In case you’ve been wondering what kind of accuracy is possible for a tactical-type rifle chambered for this mid-sized cartridge, check out this tack-driver built by gunsmith Ryan Pierce. That’s a mighty impressive 0.206″ five-shot group fired with Berger 140gr Hybrids using a Brux cut-rifled barrel. The powder was Hodgdon H4350, a very good choice for this cartridge.
Ryan reports: “Here is a 6.5×47 I built for a customer. It features a trued Rem 700 action, Brux 1:8″ Rem varmint-contour barrel, Mcmillan thumbhole stock, Surgeon bottom metal, and 3-port muzzle brake. The customer’s preferred load is the same that has worked in the last couple dozen 6.5x47s I’ve built: 41.1-41.3 grains of H4350 with 140 hybrids .050″ off the lands. This should run about 2810-2815 fps from a 26″ barrel. The 3.128″ refers to length of a loaded round from the base to ogive including the Hornady ogive comparator tool.”
Yep, It Measures Up…
Lest anyone dispute Ryan’s measurement of this group (the internet is full of nay-sayers), 0.206″ is EXACTLY what we got when we measured this group using OnTarget software. See for yourself:

Forum member Ryan Pierce set a pending new F-Class Open National Long-Range record this past Sunday at a Long Range Regional Palma Match in Lodi, Wisconsin. Ryan shot a “clean” 450 with 24 Xs in a 800/900/1000 match at Winnequah Gun Club. Once certified, Ryan’s 450-24X score tops the 449-33X record set by Robert Bock in 2008. To make the story even better, Ryan smithed the gun himself, doing his own metal and stock work! Ryan’s record-setting rig is a .284 Win with BAT action, Brux barrel, and Precision Rifle & Tool (PR&T) stock. Ryan shot Berger 180gr Hybrids pushed by H4831SC and CCI BR2s. Interestingly, Ryan set the record with a ‘dirty barrel’. By the time he finished the 1000-yard stage on Sunday, he had put over 150 rounds through his barrel since its last cleaning. Ryan wasn’t just being lazy — he had noted that the vertical tightened up the more rounds he shot.
Ryan Reveals How Record Was Set
Ryan tells us: “I had actually debated using my 6BR last weekend but didn’t and used up my last box of 180 Hybrids. They are seated .025″ off the lands with 56.0 grains of Hodgdon H4831SC and a BR2 primer. This load is running 2900 fps. I had 1 1/2 min of wind on and was favoring another half minute. I had excellent pit service, 6 seconds, by Jeff Dick. I knew he was fast so I figured ‘let’s rock and roll’. I was done in 3 to 3.5 minutes. I was pretty stoked. Halfway through the relay I started shaking pretty bad. After my last shot came up a 10 I was all smiles and couldnt believe I’d shot the 450.”
Above is Ryan with his rifle and 1000-yard target. He had two (2) sighters in the 9-ring, but the rest were 10s and Xs. Jim tells us: “As the string went on Ryan started flirting with the bottom of the 10 ring. Those pasters were removed to validate that they were indeed solid 10s.” Jim adds: “I witnessed Ryan’s 900- and 1000-yard strings and had the pleasure of signing the score card on the 1000-yard string, it was amazing to watch and see Ryan so excited about accomplishing this.”

Above you can see Ryan’s 800- and 900-yard strings on the same target. Jim See reports that: “Due to the rain delay, and some relay jockeying, Ryan ended up being the last shooter at 800 and the first shooter at 900, all on a clean target. So when [Ryan] hit the pits he took the picture, not knowing what was in his near future.” NOTE: The 800-yard stage allowed unlimited sighters, so there are a few shots out of 10 Ring. At the 900- and 1000-yard distances, two sighters were allowed at each yardage.
We congratulate Ryan for his great shooting. This was a tough record to beat. Forum member Nodak7mm says: “This was great shooting by an awesome up-and-coming shooter in the F-Class arena. Ryan is definitely a force to be reckoned with….”. Click the link below to hear Ryan talk about setting the record, and some surprising changes he made the day of the match.
Ryan Pierce .284 Win F-Open Rig Specifications
Ryan provided this info on his record-setting rifle: “The gun has a BAT ‘M’ action (Jewell trigger), Brux 32″ 1:9″ twist barrel, and a Ray Bowman (PR&T) F-Open ‘low boy’ stock with adjustable cheekpiece and adjustable buttplate. The scope is a Nightforce NXS 12-42x56mm. The barrel has 1300 rounds through it. All the metal and stock work was done by me.” Ryan’s record-setting load consisted of Berger 180gr Hybrids pushed by H4831SC and CCI BR2s at 2900 fps. This was a straight .284 Winchester.
