Accurate Cartridges — The .284 Shehane, an Improved .284 Win

F-Class Reloading .284 Winchester Win Shehane Accuracy

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 fireforming 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.

Fellow .284 Shehane shooter 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.

Is the .284 Shehane Inherently Accurate? You Better Believe It

6.5×47 Lapua — Accuracy to Spare for Tactical Applications

6.5x47 Lapua Tactical Rifle Ryan Pierce Brux Barrel H4350 Berger Hybrid

Last summer 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.

6.5x47 Lapua Tactical Rifle Ryan Pierce Brux Barrel H4350 Berger Hybrid

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.”

Ryan Pierce Sets 450-24X F-Open Record with Home-Built Gun

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.
