Fire-Forming .284 Improved Cases with Water-Cooled Railgun

Shiraz Balolia Grizzly Fire-forming railgun water cooled barrel

In the video below, Shiraz Balolia takes you through the essentials of fire-forming brass with his custom-made, water-cooled benchrest railgun. Shiraz is a current Team member (and former Team Captain) of the U.S. F-Class Open Rifle Team. Shiraz has competed on the National and World level for more than two decades, and has won multiple major International championships in 1000-yard shooting. In this video he will walk you through fire-forming cartridges in .284 Shiraz, a wildcat based on the .284 Winchester.

Fire-forming properly is a pre-requisite for accuracy in a match rifle. Done right, fire-forming can improve cartridge consistency shot to shot. Creating a fire-forming fixture like this, or even a more basic design, can save you time and potential frustration on the range, Shiraz explains. The key is getting the initial case expansion to match your competition chamber quickly but without generating excessive heat. Follow along as Shiraz takes you through the methodology of fire-forming both in his work shop and on the range.


Here Shiraz Balolia takes you through the essentials of fire-forming brass with his custom-made, water-cooled benchrest railgun.

Along with running the successful Grizzly Industrial enterprise, Shiraz is a top competitor and member of the U.S. F-Open team. He has competed in three world championships. In recent years he captured three straight Canadian National F-Class Championships (READ 3-Peat STORY). So, this guy knows his stuff.

Shiraz shows fellow shooters how to fire-form cases efficiently without burning precious match barrel life. In the video above he uses a custom-designed railgun that employs water cooling for the barrel. This is done with hoses running from a sink, so that cool water is constantly flowing through the barrel jacket.

Shiraz says the fired cartridge are actually cool to the touch because the water-jacketed barrel keeps everything at a moderate temperature. (See video at 8:00)

Sunday Gunday: Ocock Railgun May Be Most Accurate Gun Ever

Gary Ocock Rail Gun Unlimited Target Visalia CA 6 PPC IBS NBRSA
Want to see the details? CLICK HERE to view full-screen photo.

Gary Ocock railgun aggreggateCheck out those five targets. The Aggregate (average) of all five targets is a tiny 0.0840 inches! These were shot by Gary Ocock at 100 yards in a California benchrest match on August 6, 2017. Though Gary’s 0.0840 Agg beats existing records, this was not a “sanctioned” match, so Gary’s killer Agg will NOT be submitted for IBS or NBRSA records. So, sadly, the Agg won’t appear in the record books, but this remains a spectacular, verified feat of rifle accuracy, accomplished in competition.

Gary’s red railgun is arguably the Most Accurate Gun Ever Built. As far as we can determine, no one has ever shot a smaller 5-target Agg anywhere, at any time. FYI, the NBRSA Unlimited Class 5×5 Aggregate World Record is 0.1242″ shot by Jerry Lahr in 2012. Gary’s 0.0840″ Agg is much smaller.

The Unlimited Benchrest Record That Will Never Be (Official)

Report by Boyd Allen
Gary Ocock’s stunning unlimited Aggregate is beyond amazing. That’s an average of five, 5-shot groups of .0840. Shot under sanctioned match rules, but at an unsanctioned 100-yard fun match, this Aggregate is well under the current 100-yard official records of the IBS (.1386), and the NBRSA (.1242). The fourth of the five groups measured a minuscule .018, less than half the size of the existing NBRSA Unlimited record of .049 (also shot by Gary). Check it out:

When the top 15 shooters all post teen Aggs, conditions must be pretty favorable. However there were some light switchy winds — Gary said that he shot better in the left to right condition.

GUN SPECIFICATIONS
Ocock’s red Jay Young Unlimited Railgun features one major difference from Young’s typical Railgun designs. The bottom of the barrel block is integral with the top (moving part), of the gun. The barrel is Ocock’s usual 1:13.5″-twist Krieger chambered for the 6 PPC. The BAT Neuvo action* is unusual in that its lugs are horizontal at lock-up instead of the usual vertical. With horizontal lugs, both lugs maintain contact with their abutments when the action is cocked. In the more normal configuration when cocked the top lug is forced off of its seat by a combination of the angle of the trigger cocking piece interface, the pressure of the striker spring, and bolt clearance at the rear of the action.

LOAD SPECIFICATIONS
Gary shot this remarkable Agg with well-used brass, Vihtavuori N133 powder, and self-made 66gr BT bullets** seated at “jam”. This amazing Agg was shot on the second day of a 2-day Unlimited Benchrest match. On Day 1 Gary had experimented with various loads using both surplus IMR 8208 and Vihtavuori N133, but was not satisfied with the results. For his first group on Day 2, Gary tried a light load of N133. After seeing the result, however, he decided to go to the other extreme — a super stout N133 load — with the same powder. As you can see, Gary’s willingness to experiment paid off.

Gary Ocock Rail Gun Unlimited Target Visalia CA 6 PPC IBS NBRSA

Notably, Gary used light neck tension. Ocock found that for these bullets and this barrel, light neck tension worked best (contrary to “normal” N133 benchrest practice). Ocock used a bushing that only produces .001″ difference between the diameters of sized and loaded case necks.

This video shows a line-up of Rail-Guns. One of Gary Ocock’s Rails appears at the 0:35 time-mark.

Comment on Ocock’s Achievement
Congratulations to Gary Ocock for superb shooting (and smart loading). Even though the match was not sanctioned (so the Agg will never be a record), Ocock has raised the bar very high, and given us a new standard of ultimate accuracy.

Though this 0.0840 Aggregate and 0.018 group will never go into the record group, they are still noteworthy. There’s virtually no doubt that they would have survived inspection by any record committee. Except for the lack of fixed backers, an IBS requirement (for detecting cross-fires), all other conditions were met for an officially-sanctioned match.

Here is Gary with his Red Railgun at a Visalia event in October 2017. Ocock let the event’s youngest competitor, 12-year-old Gavin Lichtenwalter, shoot Gary’s new Railgun for the last three matches on Sunday afternoon. The day before, 10/21/17, Gary shot an IBS Heavy Benchrest World Record putting five shots in just 0.045 inches, as certified by the IBS record committee. Here is that group, as first measured at the range at 0.039 inches.

*The new BAT Neuvo actions are the result of a collaboration between Dwight Scott, and Bruce Thom, featuring Dwight’s ideas and BAT’s proven manufacturing expertise.

** Ocock shot his own, boat-tail match bullets, made with George Ulrich-crafted dies using Hood cores. Although he said that it had been a while since he had weighed any, his best guess was that they weigh something around 66.5 grains.

Rise of the Railguns — Potential Records Set at IBS Match

Visalia Heavy Benchrest Unlimited Railgun record Visalia CA California
Gary Ocock let the event’s youngest competitor, 12-year-old Gavin Lichtenwalter, shoot Gary’s new Railgun for the last three matches on Sunday afternoon. The day before Gary shot what should be a new IBS 100-yard, five-shot HB group record. Photo credit: Ben Zentner

Heavy Benchrest (Unlimited) rifles, also known as “Railguns”, are the most accurate competition firearms ever invented. And these amazing examples of shooting technology showed their capability recently, with potentially four (4) new records being set at an IBS Heavy Benchrest Invitational match in Visalia, California. If you are curious about the most accurate rifles on the planet, then read on…

2017 Visalia Invitational — IBS Heavy Benchrest Match

Report by Boyd Allen, IBS Exec. Vice President
There was some amazing shooting at a recent Invitational Heavy Benchrest match* held in Visalia, California on October 21-22, 2017. No less than FOUR new Heavy Benchrest (HB) records may have been set. Three individual targets were submitted for the 100-yard HB five-shot group record, a .039 by Gary Ocock (photo below), along with two targets by Jim Nicolas, a .040 and .041.

Visalia Heavy Benchrest Unlimited Railgun record Visalia CA California

Multiple Aggregate records (at both 100 and 200 yards) may also have been set. Larry Boers shot a 100-yard, five-target 0.1232 Aggregate that will be submitted for the IBS HB 100-yard, five-shot group Agg record. And Gary Ocock may have set two additional HB Agg records. Gary’s five-target 200-yard Agg (0.1310) is a potential new five-shot-per-target record, as is his ten-target Grand Agg (0.1480) (that covers 100 AND 200 yards, five targets per yardage, ten targets total).

Top Guns Come to IBS Match in California
This California match attracted some of the best Railgun pilots in the game today. On the firing line were three current NBRSA Unlimited record holders: Larry Boers (one record), Steve Kostanich (two records), and Gary Ocock (three current NBRSA UNL records, plus one HV). All three shot well enough in this match that their targets are being submitted to the IBS for consideration as Group, Aggregate, or Grand Aggregate records. NOTE: The “Heavy Benchrest” IBS category is equivalent to “Unlimited” under NBRSA rules. CLICK HERE for Complete Match Results.

Top Shooters for the Match included: Larry Boers (Two Gun, HB GrAgg1, HB 100-yd); Gary Ocock (HB 200-yd and HB GrAgg2); Francis Lee (HB 200-yd).

Two-Gun Overall Results
Visalia Heavy Benchrest Unlimited Railgun record Visalia CA California
Note: The computer software shows the results for one Grand Agg as “Heavy Varmint”. In fact the SAME HB Railguns were used for both Grand Aggs, so the “Two-Gun Agg” is actually a pair of HB Aggs.

Conditions: It rained on Friday, but Saturday and Sunday were sunny and slightly cool at first and perfect after that. Saturday at 10:00 am it was 62°, 64%, and the wind was light, increasing slightly later in the day. Sunday’s conditions were similar with a slightly higher wind speed, but still light. The wind was from the West at 3-10 mph, generally stronger closer to the firing line than down range. This normally is more of a picker’s range than a runner’s venue. However, there was some “running” of groups this weekend since rail guns are particularly suited for that style of shooting.

Hall of Famer Helps Young Novice
Along with the seasoned veterans, there was a new competitor, a 12-year-old shooting his very first match. As with life, there were highs and lows. Young Gavin started out with an equipment failure — the rifle he brought wasn’t working, so shooter Bob Hatley let Gavin borrow Bob’s bag gun. Then Gavin got some expert assistance from one of the world’s best — Hall of Famer Gary Ocock. Gary let Gavin shoot the last three 200-yard matches with Gary’s new integral block, Jay Young-built Railgun, one of the most accurate firearms on the planet. Gary shot this rig on relay #1 and let Gavin shoot it in relay #2. How many of us will ever get this kind of opportunity, much less a first time 12-year-old competitor? It’s like a school kid getting to drive an Indy-winning race car.

Bob Hatley (extreme left) stepped up to share his bag rifle with Gavin, and Gary Ocock (right of Gavin) let Gavin shoot his Railgun. Note Gavin is wearing Gary’s Hall-of-Fame jacket.

The Facility at Visala — Dale Wimp Rifle and Pistol Range
The Visalia Range has a covered firing line with 28 fixed, monolithic steel-reinforced concrete benches. The direction of fire is north. The cover extends well past the front of the benches as does the concrete. There are covered loading areas both at the level of the benches, directly behind them, and one level up farther to the rear. The firing line and range are below the level of the surrounding land, having been excavated in flat ground with the material from the excavation surrounding the range on three sides, higher in the back, forming an impact berm. A major construction project is about to be finished that will extend the range to 300 yards, and provide a new 10-station, 25-yard pistol range.

Surrounded by fields, the Visalia Range is located in California’s Central Valley, a rich agricultural area.

Notables on the Visalia Firing Line

Three of the competitors at the match deserve special mention because of their recent accomplishments in the world of Benchrest shooting and the interesting equipment they had on display.

Visalia Heavy Benchrest Unlimited Railgun record Visalia CA California

Jim Nicholas was on fire on Saturday. During Saturday morning’s 100-yard Aggregate he shot a .040 in the fourth match, and a .041 in the fifth. Both targets and the .039 that Gary Ocock shot were sent in to be measured for a record. All are substantially smaller than the current record, Hap Zeiser’s .063. In the photo above, note the tuner. Jim adjusted a little less than 8 degrees just before he shot .040 in the fourth match and .041 in the fifth. That must have been the “sweet spot”. Jim’s blue Railgun, built by Craig Kinsler, features a barrel block that is integral with the rig top. This is like the new Jay Young Railgun Ocock shoots.

Visalia Heavy Benchrest Unlimited Railgun record Visalia CA California

Larry Boers owns the NBRSA Unlimited, 100-yard 10-shot group record (.097). This makes the fourth time that he has won the Two-Gun Overall for this match. Larry is not just a trigger-puller — he makes his own bullets and chambers his own barrels. This year he shot a bullet he still lists under his bullet-making mentor’s name (Del Bishop) a 65 grain, double radius 5/9 FB made from J4 .790 jackets, out of a Nemi point die. Del originally made the bullet and the story is that Nemi at first refused to make the die because he was sure that it wouldn’t shoot well. Later, after some cajoling by Del, he made it, tried a few and excitedly called Dell to tell him just how good the bullets shot. Larry set his record shooting a .750 jacket short BT (.040) bullet from the same die.

Visalia Heavy Benchrest Unlimited Railgun record Visalia CA California

Steve Kostanich, a long-time competitor and highly-respected gunsmith from Washington State, recently received official confirmation that he will go in the record books with a pair of 10-shot Unlimited NBRSA world records. The first record is a 10-shot 200-yard 0.1839 Aggregate, while the second is Steve’s 100-200 yard 0.1951 Grand Aggregate.

Parting Shot — This is what happens when you set your Wind Flag stand too high.

Visalia Heavy Benchrest Unlimited Railgun record Visalia CA California


* Course of Fire: This was a two-day Heavy Benchrest (aka HB or “Unlimited”) weekend match with targets at 100 and 200 yards, five shots per target. Saturday all shooting was at 100 yards. Sunday all shooting was at 200 yards. There were two (2) Grand Aggregates. One Grand Agg combined Saturday morning (100) with Sunday afternoon (200). The Second Grand Agg combined Saturday afternoon (100) and Sunday morning (200). The match had two HB Grand Aggs because only one class of gun (Heavy Benchrest or “Unlimited”) was shot. The computer software shows the results for one Grand Agg as “Heavy Varmint”, but all matches were for Heavy Benchrest (Unlimited) guns. NOTE: Some competitors did shoot bag guns as these are allowed under HB/Unlimited rules.

IBS Match Report: 2017 Group Benchrest Nationals in Michigan

IBS Group Nationals international benchrest shooters 2017 Holton Michigan Powderpuff 6PPC Wayne Campbell Tony Boyer
The IBS Groups Nationals has a 4-man team competition based on the HV Grand Aggregate results. The 2017 winning team was a “Murderer’s Row” consisting of Wayne Campbell, Billy Stevens, Bart Sauter, and Larry Costa. Each boasts Hall of Fame and/or multiple World Team accomplishments. Hamming it up in the background is HOF shooter Jack Neary.

2017 IBS Group Benchrest National Championships

Holton Gun & Bow Club, Holton, Michigan
August 14-19, 2017

Report by Jeff Stover, IBS President
This year the 2017 IBS Group Benchrest Championship was held at the Holton Gun & Bow Club, in Holton, Michigan. This is a pretty facility boasting an impressive firing line with forty (40) concrete benches. Monday morning in western Michigan saw the Heavy Bench (HB) shooters hauling their big railguns to the line. Hall of Fame and multiple World Team shooter Wayne Campbell shot a nice .1858 aggregate for five 10-shot groups. The only other “Teen Agg” was Iowa’s Dave Coots with a .1978. Wayne’s win foretold what was to come the rest of the week.

Wayne Campbell and Jeff Summers Put on a Show
On Tuesday, the bag guns came out for Light Varmint (LV) and Sporter (SP). Mr. Campbell maintained his mojo, shooting yet another “Teen Agg”. Wayne’s .1788 edged fellow HOF member Larry Costa’s .1854. The Light Varmint 100 was also contested on Tuesday. Peter Smith shot a very fine .1658 to beat out Canadian Bill Mitchell at .1960.

Wednesday was reserved for Heavy Varmint (HV) at 100 yards. Holton is Bob Scarbrough’s home range, but he can shoot “lights out” anywhere. Nevertheless, his .1518 had to be satisfying. Wayne Campbell, still on fire, laid down a .1694. In third place, Tennessean Jeff Summers posted a .1800. Mr. Summers is always near the top of any benchrest leader board. He is coming off another Super Shoot win. Most of the time Jeff does not win the small group of the day, but he wins many Aggregates. He is one of the most mistake-free shooters in the game.

Benchrest for Group Basics — Four Classes at Nationals
IBS group competition is contested at 100 and 200 yards. At the National Championships, it takes thirty targets of five shots each and ten targets of 10-shot groups to win a “4 Gun Nationals”. That includes four (4) gun classes: Light Varmint, Heavy Varmint, Sporter, and Unlimited. For all practical purposes, the first three are known as “bag guns” while the heavy bench rifles are “railguns”.

In fact, most competitors shooting a bag gun opt for a single rifle, which has been benchrest standard for decades: a 10.5-lb rifle chambered in 6PPC. This can compete in three classes: Sporter, Light Varmint, and Heavy Varmint. The fourth class shot at the Nationals is Unlimited (aka Heavy Benchrest or “HB”). This class features the big, heavy railguns — the most sophisticated Benchrest rigs of all which shoot 10-shot groups at 100 and 200 yards.

For the IBS Nationals, group-shooting competition features 100-yard targets for the first three days followed by three days at 200 yards. Six days total. It is done this way to require only one change of wind flags. Nationals competition requires “full rotation”. That means that every time a shooter goes to the line for the next match target, he or she must move a requisite number of benches to the right. At the end of the day a shooter will shoot across the full width of the line. Some ranges offer unique properties that render some parts of the range harder or easier to shoot small groups. Bench rotation is important to even out those factors.

Thursday was set for 200 yards. Starting off was Heavy Bench (HB), the big railguns. Upper Midwest shooter, Mark Buettgen shot steadily for a .2406 Agg, aided by a small .378. His largest group was a .527. Consistency wins bench matches. Lee Hachigian drove in from the Detroit area with his railgun to be next to the winner with a .2608.

On Friday, two Aggs were shot, Light Varmint and Sporter. Larry Costa nearly nicked a Teen Agg to win LV 200 with a .2027. Lurking high in the standings once again was Jeff Summers and his .2352. Wayne Campbell was not asleep. He was merely third at .2480. The Sporter competition was won by the best benchrest shooter of all time, Tony Boyer. Tony shot a .2287 to edge Billy Stevens. Mr. Boyer added another Hall of Fame point. His 170 points are 120 more than the next shooter (Lester Bruno, no slouch!) in the ranking.

The HV guns came out to contest 200 yards on the last day of the Nationals. Jeff Summers worked a .1868 to the winner’s circle. The always tough Larry Costa was close at .1929.

At the IBS Group Nationals, shooters compete for Grand Aggregate (100+200) honors in four classes: LV, HV, Sporter, and HB. In addition, there are multi-gun titles: 2-Gun (all HV and LV targets in 100 & 200); 3-gun (all HV, LV, SP in 100 & 200), and 4-gun (all HV, LV, SP and Heavy Benchrest in 100 & 200).

The Grand Aggregate (100+200) winners were:
Heavy Varmint: Bob Scarbrough, Jr. (.1824)
Light Varmint: Jeff Summers (.2313)
Sporter: Wayne Campbell (.2119)
Heavy Bench: Lee Hachigian (.2374)

In the prestigious multi-gun competition, Jeff Summers won the 2-Gun. Wayne Campbell added more HOF points by winning BOTH the 3-Gun AND the 4-Gun. With his impressive 3-Gun and 4-Gun victories, the talented Mr. Campbell claimed the title of Top Overall shooter after six days of trigger-pulling.

2017 IBS Nationals Powderpuff Exhibition Shoot
For decades, IBS hosts an exhibition shoot on the afternoon of a day when only one Aggregate is contested instead of two. It is called the Powderpuff and is intended to allow family members and others who do not shoot competitively to give benchrest shooting a try. Each shooter is assisted by a coach who instructs the shooter. World-class shooters such as Billy Stevens and Bob Scarbrough give their time and talents to assist the novice competitors. There is no time limit to rattle the inexperienced shooters.

The competition is financially supported by the IBS President’s Fund. This year, at Holton in Michigan, we had four youth and 11 adult competitors. Chris Jeffers won the adult category with a nice .204″ group, while Jake Henderson put his five shots into a .244″ to win the youth division. Congratulations to all the Powderpuff competitors — we hope this inspires them to get more involved in Benchrest shooting.

Insane Railgun Accuracy — Lozano Sets Two World Records

Benchrest NBRSA Unlimited Railgun Grand Agg World Record, Visalia

You are looking at one of the most impressive examples of precision shooting in history. On each of those five targets is a five-shot group made at 100 yards. This is the best set of five targets ever shot consecutively at 100 yards in the history of firearms competition on this planet. That’s right, nobody has ever drilled a better set of five, five-shot targets. The combined Aggregate for these five targets is a stunning 0.1014″, with the individual groups measuring: 0.102″, 0.168″, 0.123″, 0.053″, and 0.061″. So, two of the five groups were in the Zeros. And the 0.1014″ Agg handily beats existing world records.

Benchrest NBRSA Unlimited Railgun Grand Agg World Record, Visalia

This is an amazing accomplishment that beats both the existing NBRSA and IBS records. The NBRSA Record 100-yard Unlimited 5×5 Aggregate is 0.1242 set by Jerry Lahr in 2012. The IBS Record Heavy Benchrest 100-yard Aggregate (for five, 5-shot groups) is 0.134″, set by R. Howell in 2004.

But there’s more…

Lozano Grand Agg of 0.1226 also Breaks IBS and NBRSA World Records
George Lozano also shot a superb five-target Aggregate at 200 yards: 0.1439. This gave him a combined 100 + 200 Grand Aggregate of .1226 which is also a new world record. NOTE: for the 200-yard Agg, the actual group measurements (in inches) are summed, averaged and then divided by two to provide equivalency with the 100-yard results. Lozano’s actual group measurements at 200 yards were: 0.205″, 0.307″, 0.220″, 0.409″, and 0.298″. As averaged and divided by two, that is 0.1439. When combined with George’s 0.1014 100-yard Agg, Lozano’s 100+200 Grand Agg is a stunning 0.1226.

Benchrest NBRSA Unlimited Railgun Grand Agg World Record, Visalia

Lozano’s 0.1226 Grand Agg breaks both NBRSA and IBS World Records. The current NBRSA Unlimited Grand Agg Record for five, 5-shot groups at both 100 and 200 yards is a 0.133 by Dave Dowd in 2012. The equivalent 100 + 200 IBS Heavy Benchrest Grand Agg Record is a 0.1575 by Lester Bruno in 2004.

Benchrest NBRSA Unlimited Railgun Grand Agg World Record, Visalia

The talented shooter, George Lozano (shown above), was modest about his achievement: “Thanks, guys. I appreciate your very kind compliments. It was a good Father’s Day weekend and a fun match.”

NOTE: These records are pending verification by the NBRSA official records committee. But based on the numbers we’ve seen, it looks like Lozano will soon find his name in the record books.

Technical Details
We don’t know much about George Lozano’s load — either the powder or bullet. We’re told he was shooting a 6PPC cartridge in an Unlimited Benchrest rig, also known as a “railgun”. Here is a photo of a modern benchrest railgun. This is NOT Lozano’s record-breaking rig, but it shows the type of hardware used in the modern Unlimited Class.

Navy’s BAE Railgun Shoots Projectile 203 Kilometers at Mach 7

Navy BAE Railgun

How would you like to “reach out and touch” someone 203 kilometers away (about 110 nautical miles)? Well America’s Navy may soon be able to do exactly that with an amazing new, high-tech weapon system. BAE Systems has developed (and successfully test-fired) an electro-magnetic rail gun that fires a 23-lb projectile at Mach 7 — (about 5300 mph or 7800 fps). This futuristic weapon can send its projectile 110 nautical miles (126 mi / 203 km), five times the range of the big 16″ guns on WWII-era battleships. This railgun has serious “knock-down” power — at Mach 7, that projectile carries a whopping 32 megajoules of energy. BreakingDefense.com says: “23 pounds ain’t heavy. But it sure hurts when it hits you going at seven times the speed of sound.”

Watch Video to See Navy Rail-Gun in Action:

The latest prototype of the railgun developed by defense contractor BAE, in conjunction with the Office of Naval Research, can accelerate a projectile up to Mach 7 within 10 milliseconds. The gun uses no gunpowder to generate propelling force. Compared to an item on a smaller scale, the railgun projectiles resemble crossbow darts, except they deliver such massive Kinetic Energy they don’t need to carry explosive ordnance. The railgun can strike targets 110 nautical miles away.

To prepare a charge, the ship stores electricity in the pulsed power system. Next, an electric pulse is sent to the railgun, creating an electromagnetic force accelerating the projectile. Because of its extreme speed, the projectile eliminates the hazards of storing high explosives in the ship. Each shot costs about $25,000 — but that’s cheap compared to the price of a missile.

“It’s like a flux capacitor,” chief of Naval research Rear Admiral Mathias Winter said in a video posted by Reuters Friday. “You’re sitting here thinking about these next generation and futuristic ideas, and we’ve got scientists who have designed these, and it’s coming to life.”

The Electromagnetic Railgun Innovative Naval Prototype (INP) was initiated in 2005. The goal during Phase I was to produce a proof-of-concept demonstration at 32 mega-joule muzzle energy, develop launcher technology with adequate service life, develop reliable pulsed power technology, and assess component risk reduction for the projectile.

Navy BAE Railgun

Phase II, which started in 2012, advanced the technology to demonstrate a repeatable-rate fire capability. Thermal-management techniques required for sustained firing rates will be developed for both the launcher system and the pulsed power system. The railgun will begin testing at sea in 2016.

How would you like to “reach out and touch” someone 110 nautical miles away? Well America’s Navy may soon be able to do exactly that with an amazing new, high-tech weapon system. BAE Systems has developed (and successfully test-fired) an electro-magnetic rail gun that fires a 23-lb projectile at Mach 7 — (about 5300 mph or 7800 fps). This futuristic weapon can send its projectile 110 nautical miles (126 mi / 203 km), five times the range of the big 16″ guns on WWII-era battleships. This railgun has serious “knock-down” power — at Mach 7, that projectile carries a whopping 32 megajoules of energy. BreakingDefense.com says: “23 pounds ain’t heavy. But it sure hurts when it hits you going at seven times the speed of sound.”

The latest prototype of the railgun developed by defense contractor BAE, in conjunction with the Office of Naval Research, can accelerate a projectile up to Mach 7 within 10 milliseconds. The gun uses no gunpowder to generate propelling force. Compared to an item on a smaller scale, the railgun projectiles resemble crossbow darts, except they deliver such massive Kinetic Energy they don’t need to carry explosive ordnance. The railgun can strike targets 110 nautical miles away.

To prepare a charge, the ship stores electricity in the pulsed power system. Next, an electric pulse is sent to the railgun, creating an electromagnetic force accelerating the projectile. Because of its extreme speed, the projectile eliminates the hazards of storing high explosives in the ship. Each shot costs about $25,000 — but that’s cheap compared to the price of a missile.

“It’s like a flux capacitor,” chief of Naval research Rear Admiral Mathias Winter said in a video posted by Reuters Friday. “You’re sitting here thinking about these next generation and futuristic ideas, and we’ve got scientists who have designed these, and it’s coming to life.”

The Electromagnetic Railgun Innovative Naval Prototype (INP) was initiated in 2005. The goal during Phase I was to produce a proof-of-concept demonstration at 32 mega-joule muzzle energy, develop launcher technology with adequate service life, develop reliable pulsed power technology, and assess component risk reduction for the projectile.

Phase II, which started in 2012, advanced the technology to demonstrate a repeatable-rate fire capability. Thermal-management techniques required for sustained firing rates will be developed for both the launcher system and the pulsed power system. The railgun will begin testing at sea in 2016.

Murdica’s Masterpiece — Just About as Good as It Gets

Lou Murdica Railgun NBRSA Record one-hole 6PPC Berger Bullets kelbly Action

Sometimes superlatives really aren’t necessary. Just look at that target. Yes that is FIVE shots (although it truly appears like one hole). And it is centered! This remarkable group, measured at 0.039″, was shot by Lou Murdica in Phoenix on January 3, 2015. Lou drilled this group with his 6 PPC railgun. Rounds were loaded with Accurate LT-32 powder and Berger 65gr BT bullets. The target will be submitted to the NBRSA as a potential new 100-yard Benchrest record in the Unlimited (Railgun) Class. The current NBRSA record small group (Unlimited) is a 0.049 shot by Hall-of-Famer Gary Ocock in 2009.

This wasn’t the only tiny group shot by Lou over the weekend. Murdica shot a sizzling 0.1262 five-target 100-yard Unlimited Aggregate. That 0.1262 Agg will also be submitted for consideration as a possible record. Here are the individual group sizes: 0.104, 0.183, 0.201, 0.104, 0.039. At this match Lou won both the Unlimited and Sporter class. “It was a great weekend” Lou reported.

About the Gun
What kind of rifle can put five shots in one hole? Lou was shooting an Unlimited-class railgun. This return-to-battery rig (a Kensler railgun) allows the shooter to focus on firing at the perfect time for the conditions. Lou’s Kensler railgun (see below) features a Kelbly top-loader Grizzly action, Shilen 6-groove barrel, and March 10-60X scope. The Shilen is chambered for the 6 PPC cartridge. But there’s something special about this particular 6 PPC — read on….

Radical New Reamer Design from PT&G
Lou used a new chamber reamer from Pacific Tool & Gauge (PT&G) with special geometry in the leade/throat section. Called a “Bore Rider” (or sometimes “bore-runner”), this new reamer design cuts a staged, variable taper in the leade/throat area that is quite different than the taper in a typical throat. It’s a little hard to explain, so we’ve included the 6 PPC Bore Rider reamer print below. (Download the PDF file for a better view.) Experts should look at the leade angle(s), freebore, and throat dimensions. You may be surprised. Dave Kiff of PT&G says this Bore Rider design has worked successfully for other cartridge types/calibers as well. Apparently this design helps the bullet center up smoothly in the bore before the bullet engages “hard” in the rifling — or so we’ve been told.
