Locking Handle Kits for Swivel Bipods

KMW Pod-Loc BipodIf you’ve ever used a Harris Swivel Bipod, you know that, without tools, it is difficult to put enough tension on the swivel locking knob to really lock the unit solid. And, if you do manage to get the knob really tight (perhaps by using pliers), it is difficult to loosen with fingers alone.

That was why Terry Cross and the folks at KMW Long Range Solutions invented the Pod-Loc™. This system replaces the knurled swivel tension knob with a push-button adjustable handle. Using the handle you can easily set the swivel tension at any level from loose to “rock solid”. And you can release tension to adjust the bipod to different terrain just as easily. The KMW Pod-Loc™ retails for about $27.00 at Brownells.com and Sinclair Int’l.

Pod-Loc™ Installation Instructions

How to Build Your Own Bipod Swivel Locking System
While we use genuine KMW Pod-Locs on our rifles, readers on a tight budget, or who have a large collection of bipod-equipped rifles, can economize by putting together their own swivel locking systems from off-the-shelf components. You need two parts per installation: a push-button swivel handle and a 3/16″ spacer. Levers and spacers are both available online from www.T-Nuts.com. The spacer is part #SS1 ($1.00). T-Nuts offers a variety of suitable handles, ranging in price from $5.80 to $8.50. So, by sourcing the parts, you can outfit three bipods with swivel adjusters for the cost of one Pod-Loc.

T-Nuts Bipod Handle lock

We recommend the Nylon/Stainless BPL/NS model ($7.70), but you may prefer the all-metal BPL-Z ($7.00), or the shorter BPL-Micro model ($8.25). The compact Micro lock does not protrude past the body of the bipod, yet is still easily grasped. T-Nuts supplies one 3/16″ spacer with most of its bipod handles. T-Nuts handles are also available with a metric M6x1.0 thread for use with imported bipods such as Outers and Rockport.

Installation is Easy — With the Right Socket
To install a swivel locking system, first you’ll need a 1/4″ socket to remove the keeper nut from the threaded pivot rod. (During this process, you’ll need to keep pressure on the pivot rod retaining pin on the opposite side of the bipod.) Don’t try to remove the keeper nut with pliers or an open-end wrench. You really need the correct socket. Once that keeper nut is removed, then unscrew the knurled tension knob/ring. This is attached to the same threaded shaft as the keeper nut but you should be able to remove it without tools.

After the knurled tension ring is off, it is easy to put your handle on the bipod. First slip the 3/16″ spacer over the threaded pivot rod. Keeping finger pressure on the pivot rod retaining pin (on reverse side), then spin on the T-Nuts handle. Rotate the handle inwards until it firmly locks the bipod swivel mechanism. By pushing the button in the head of the handle, you can swing the handle left or right to set its position without altering the swivel tension.

Amazing! Wagner Shoots 0.349″ (50-2X) Group at 600 Yards

Rodney Wagner 0.349 IBS Light Gun RecordThis is one of the most amazing feats of precision shooting ever recorded. In an IBS 600-yard Benchrest match today at the Piedmont range (Rutherfordton, NC), Forum member Rodney Wagner shot a 0.349″ five-shot group at 600 yards. That smashes the existing 0.699″ IBS Light Gun Record (and it’s way smaller than the NBRSA record as well). To top that, the group was centered up for a 50-2X score, which establishes another record (50 score with small-group tie-breaker). Rodney (aka “Eggman” on the Forum) was shooting a 17-lb IBS Light Gun with a Brux barrel chambered for the 6mm Dasher, a popular improved version of the 6mm BR Norma cartridge. Rodney was shooting 32.5 grains of Varget, with CCI 450 primers, and Berger 108gr BTs, seated .020″ away from the lands.

Stay tuned — we will have more information soon. Our friend Sam Hall was on hand to interview Rodney at the Piedmont range. Click “PLAY” button below to hear Rodney talk about his rifle and his load:

[haiku url=”http://accurateshooter.net/Video/wagnertalks.mp3″ title=”Wagner Talks about 600-Yard Record Group”]

Rodney Wagner 0.349 IBS Light Gun Record

Record-Breaking Family — Like Son, Like Father
Here’s an interesting factoid: In 2008, Rodney’s teen-age son set the IBS 600-yard Light Gun record with a .711″ five-shot group, combined with an Aggregate of 1.628″. That Agg was itself an IBS record (until Chad Jenkins recorded an 1.5009″ Agg in 2012). Rodney’s son was shooting a 6BRX. The 600-yard group record was then lowered by Rodney’s friend Sam Hall, who shot a 0.699″ group in 2010. Sam also set the current 600-yard LG score record with a perfect 50, but that should be eclipsed by Rodney’s 50 score based on tie-breaker by group size.

Look at that target and try not to be astonished! When this editor saw the group, I was honestly stunned and speechless. Consider this, one MOA at 600 yards is 6.282 inches. So Rodney’s 0.349″ group works out to 0.055 MOA. That’s what a mid-zero group at 600 yards looks like boys and girls….

Remington Announces $32 Million Ammo Plant Expansion

Current demand for loaded ammunition and reloading components is very high. To meet this demand, ammo imports into the USA have nearly doubled. But supplies are still short. One reason is that domestic ammo manufacturers are already operating at full capacity — and they have been doing so for the past decade or so. The machines just can’t run any faster…

Now an important domestic ammo-maker has committed to a significant increase in production capacity. Remington Arms Company, LLC (“Remington”) recently announced a major expansion of its Lonoke (Arkansas) Ammunition Plant. Remington will spend $32,000,000 to add new structures and machinery.

Remington Lonoke Ammunition Plant

Work on the expansion, which will include the construction of a new building, is expected to begin second quarter of 2013. The $32 million expansion plan is projected to be in operation by the second quarter of 2014. The Remington’s Lonoke Ammunition Plant, opened in 1969, produces a wide variety of commercial ammunition.

“We continue to invest in all of our manufacturing operations because we are committed to ensuring quality, increasing product availability, and improving on-time delivery. This significant investment in Lonoke is a testament to that commitment. Our customers can count on Remington to invest in its manufacturing operations in order to ensure that its facilities are state-of-the art”, said Kevin Miniard, Chief Operating Officer of Remington.

NSSF Splits with Reed, Seeks New SHOT Show Management

NSSF Shot Show ReedThe National Shooting Sports Foundation (NSSF), the trade association for the shooting industry, is severing its ties with British-based Reed Exhibitions. On May 9th, NSSF announced that it has reached an agreement with Reed Exhibitions to terminate the contract the parties had for the management of the SHOT Show. Accordingly, effective immediately, Reed Exhibitions will no longer be manager and producer of the SHOT Show. NSSF is now actively engaged in the process of identifying a new show management company to manage and produce the SHOT Show beginning with the 2014 SHOT Show in Las Vegas.

The NSSF stated: “Reed Exhibitions provided excellent service to NSSF and the customers of the SHOT Show for more than three decades, however, the company’s decision to restrict the sale of certain types of firearms this year at its consumer hunting and fishing show — an event unrelated to NSSF and the SHOT Show — was in conflict with NSSF’s mission to serve the shooting sports industry. As a result, both organizations decided it was in the best interest of the SHOT Show to end their relationship.”

Reed Exhibitions had banned AR-platform rifles and other semi-automatic, mag-fed firearms from the 2013 Eastern Sports and Outdoor Show (ESOS) in Pennsylvania. As a result, consumers complained and many exhibitors boycotted the show. Ultimately, the ESOS was postponed. (Related ESOS Story)

The SHOT Show — the Shooting, Hunting and Outdoor Trade Show — is owned and sponsored by NSSF. It is the largest and most comprehensive trade show for all professionals involved with the shooting sports, hunting and law enforcement industries. The 2014 SHOT Show will be held January 14-17 at the Sands Expo and Convention Center in Las Vegas.

Large vs. Small Flash Holes in .308 Win Brass

Conventional .308 Winchester brass has a large primer pocket with a large, 0.080″-diameter flash hole. In 2010, Lapua began producing special edition .308 Win “Palma” brass that has a small primer pocket and a small flash hole, sized 1.5mm (.059″) in diameter. Tests by U.S. Palma Team members showed that the small-flash-hole .308 brass possibly delivers lower Extreme Spread (ES) and Standard Deviation (SD) with some bullet/powder/primer combinations. All things being equal, a lower ES should reduce vertical dispersion at long range.

Why Might a Small Flash Hole Work Better?
The performance of the small-flash-hole .308 brass caused some folks to speculate why ES/SD might be improved with a smaller flash hole. One theory (and it’s just a theory) is that the small flash hole creates more of a “jet” effect when the primer fires. German Salazar (Rifleman’s Journal Editor) sought to find out, experimentally, whether this theory is correct. German explained: “During one of the many internet forum discussions of these cases, Al Matson (AlinWA) opined that the small flash hole might cause the primer flash to be propagated forward more vigorously. In his words, it should be like shooting a volume of water through a smaller nozzle, resulting in a flash that reaches further up the case. Now that kind of comment really sparked my curiosity, so I decided to see what I could see.”

More Primer Testing by Salazar
You can read more about this test and other primer experiments on RiflemansJournal.com.

Salazar Primer Tests: Small Rifle Primer Study | Large Rifle Primer Study

Large and Small Flash Hole .308 Cases — But Both with Small Primer Pockets
To isolate the effect of flash hole diameter alone, German set up a test with the two types of .308 case that have a small primer pocket: Remington BR brass with a 0.080″ flash hole and Lapua Palma brass with a 0.062″ flash hole. NOTE: German reamed the Lapua brass to 0.062″ with a Sinclair uniforming tool, so it was slightly larger than the 0.059″ factory spec. The Remington brass has a .22 BR headstamp as this brass was actually meant to be re-formed into .22 BR or 6 BR before there was factory brass available for those cartridges.

.308 Winchester Flash Holes

German set up his primer testing fixture, and took photos in low light so you can see the propagation of the primer “blast” easily. He first tested the Remington 7 1/2 primer, a primer known for giving a large flame front. German notes: “I thought that if there was a ‘nozzle effect’ from the small flash hole, this primer would show it best. As you can see from the photos, there might be a little bit of a flash reduction effect with this primer and the small flash hole, the opposite of what we expected, but it doesn’t appear to be of a significant order of magnitude.”

Lapua Palma case, 0.062″ Flash Hole, Remington 7.5 Primer.

Next German tested the Wolf .223 primer, an unplated version of the Small Rifle Magnum that so many shooters use. German notes: “This is a reduced flame-front (low flash) primer which has proven itself to be very accurate and will likely see a lot of use in the Lapua cases. With this primer, I couldn’t detect any difference in the flash produced by the small flash hole versus the large flash hole”.

Palma case, 0.062″ Flash Hole, Wolf 223 Primer.

German tells us: “I fired five or six of each primer to get these images, and while there is always a bit of variance, these are an accurate representation of each primer type and case type. You can draw your own conclusions from all this, I’m just presenting the data for you. I don’t necessarily draw any conclusions as to how any combination will shoot based on the pictures.”

Results of Testing
Overall, looking at German’s results, one might say that the smaller diameter of the small flash hole does not seem to have significantly changed the length or size of the primer flame front. There is no discernible increased “jet effect”.
