Here’s a new product for shooters who need to make rapid zoom changes with their optics. The MGM Switchview is a small, lightweight lever that clamps around the power adjustment ring of variable power scopes. Made from anodized 6061/T6 aluminum, the Switchview allows the user to quickly adjust the scope’s power setting with a push or pull of the lever, without taking your head off the gun. That should help 3-gun competitors who must rapidly switch from near to far targets and back again.
The MGM Switchview works with short, tactical optics as well as high-magnification long-range scopes. Only slightly taller than most target style turrets, the lever is easy to use, even while wearing gloves or in slippery or wet conditions. The manufacturer says that: “Whether you are glassing a large area for a target and then zooming in to make the shot without loosing your sight picture, or you need to transition from far targets to [close] targets in a hurry, the MGM Switchview will get to the magnification setting you need quickly and easily.”
The MGM Switchview is now available for a variety scopes, including the Burris XTR, Leupold CQT, Leupold Mark IV (illum. reticle), Millet 1-4x24DMS, and Nightforce NXS. And soon MGM plans to build Switchviews for the IOR Valdada 1-4 and 1.4-8, Leupold VXII and VXIII, and Nightforce NXS Compact.
MGM Switchview zoom levers cost $59.95 and come standard in anodized black. However, the levers can be special ordered in custom colors for an extra $12. (Add 3 weeks delivery time for custom color orders.)
For more info, visit MGMswitchview.com. To order, call 208-454-0555 or 888-767-7371 (toll free), or email travis [at] mgmtargets.com. You can also contact Mike Gibson Manufacturing, 17891 Karcher Rd., Caldwell, ID 83607 .

 Krieger Barrels, respected maker of cut-rifled match and hunting barrels, announced it will offer 5R rifling for 6mm, 6.5mm, 7mm, and .308 caliber barrels. This kind of rifling features 5 lands and 5 grooves, but the lands are angled (slanted) on the sides (rather than 90°) for a gentler transition between land and groove. Krieger’s 5R rifling slants BOTH the leading and trailing edge of the lands (unlike “ratchet” rifling which is angled on one side only). 5R rifling also places each land opposite a groove. Having lands opposing grooves, along with slanted sides on the lands, is thought to give a better gas seal and reduced fouling. Additionally, some folks believe 5R rifling reduces jacket deformation by displacing less jacket metal. Overall, proponents of 5R rifling say it helps a barrel foul less and deliver more velocity than conventional rifling.
5R rifling will add $30 to the cost of a Krieger barrel. Krieger will NOT offer 5R rifling for gas gun barrels. Additionally, 5R rifling is offered only for constant twist-rate barrels. So, you can NOT get a gain twist barrel with 5R rifling. At this time 5R rifling is limited to 6mm, 6.5mm, 7mm, and 30 caliber bores, as listed in Krieger’s official announcement:
“Thanks to approval by Boots Obermeyer, Krieger Barrels, Inc. is now offering the true Obermeyer 5-R rifling pattern as an option on limited calibers with our barrels. We are very proud of the fact that Krieger Barrels was chosen as the only Obermeyer-approved maker of his style of 5-R rifling in North America. At this time we are limiting the 5-R option to the calibers listed below, but may offer others in the future as greater demand arises. There is a $30.00 up-charge to the base cost of the barrel for 5-R rifling. Currently available calibers:
– 6mm (.236″ & .237″ bore diameters, .243″ groove)
– 6.5mm (.256″ bore, .264″ groove)
– 7mm (.277″ bore, .284″ groove)
– .30T Palma (.3065″, .3070″ & .3075″ groove diameters)
– .308 cal (.300″ bore, .308″ groove)
5-R rifling is ONLY available in standard bore/groove dimensions listed and standard twist rates at this time. Please call if you have questions about availability of a certain caliber/twist combination. Please note, we are not, and have no plans to offer 5-R rifling in our finished ‘Gas Gun’ lines of M14, M1 Garand, AR-15, and AR-10 variants.”
5R Rifling in Production Guns
In the past, limited runs of Remington 700 tactical rifles, including some LE and SS (stainless special) models, have been offered with factory hammer-forged 5R barrels. These rifles have a reputation for shooting faster and more accurately than Rem 700s with conventional factory barrels. The Remington 5R barrels, though based on Obermeyer designs and similar to Mike Rock 5R barrels produced for the Army’s M24 sniper rifles, are NOT cut-rifled, but are produced in-house using the hammer-forging process.
Thompson/Center (T/C) Icon and Venture rifles currently feature 5R factory barrels. On T/C 5R barrels, the sides of each land are cut at a 65° angle vs. a 90° angle for standard rifling. See diagram. T/C claims that “because the edges of each land do not cut into and deform the bullet jacket… there will be less jacket fouling in the grooves”. T/C says this produces “greater bullet stability over multiple shots, and ultimately a rifle that’s easier to clean[.]”

Here’s a new product we found on SWFA.com. Minox, famed maker of miniature cameras, has released the new Minox Weatherstation to compete with the Kestrel weather meters. The Minox is very compact and very light. It measures 4.68″ H x 2.28″ W and is just 3/4 of an inch thick. And it weighs just 2.36 ounces (67 grams)! This is definitely light and small enough to be carried in a shirt pocket.
 The Minox Weatherstation has all the functions you’d expect, plus a few more: Wind speed, Barometer, Altimeter, Thermometer, Hygrometer (Humidity), Windchill, Dewpoint, Clock, Stop-Watch, Alarm, Timer, Race Timer. Of course it can display both °Celsius and °Fahrenheit, and the Hygrometer reads from 1% Relative Humidity through 100% Relative Humidity. The barometer function uses five graphically arranged columns on the LC display to show not just the current air pressure hPa, but also changes which have occurred in the last 24 hours.
We like the fact that the Minox offers timing functions as well as weather data. This way the Minox can do double-duty as a match timer. That’s one less piece of kit to bring to the range.
 With a “street price” of $249.00, the Minox Weatherstation is priced on a par with the Kestrel 4000 and is about fifty bucks cheaper than Kestrels’ top-of-the-line 4500 model. How does the Minox stack up against the Kestrels? Well, the Kestrel 4000 outputs Density Altitude, while the Minox (apparently) does not. The Kestrel 4000 can also record data points and download these to a computer. The Minox doesn’t offer a PC interface. The more expensive Kestrel 4500 has a digital compass so it can plot wind directions (crosswind, headwind, tailwind). It seems then, that the main advantages of the Minox are compact size and light weight (2.4 oz. for Minox vs. 3.6 oz. for Kestrel 4000).

In our report about the new Tactical Rimfire discipline pioneered in California, we predicted that the major manufacturers would eventually develop rifles tailored for this fun, low-cost shooting sport. Sure enough, Ruger has released a new version of its popular 10/22 rifle that would be well-suited for tactical rimfire matches.
The new Ruger 10/22VLEH Target Tactical Rifle (TTR) features a Hogue OverMolded® synthetic stock, and a compact 16-1/8″ bull barrel (.920″ OD). The Hogue stock comes with double palm swells, a varminter-style forend, and sling swivel studs. Ruger’s TTR ships with a scope rail on top of the receiver, and Ruger includes an adjustable (non-swivel) bipod with the rifle.
Overall, there is nothing really ground-breaking about this rifle, but Ruger has included some useful upgrades (stock, scope rail, bipod), that make the rifle more suitable for gun games. Rather than buy a low-end 10/22 and toss the barrel and original stock, a shooter can now buy a 10/22 that’s pretty much ready to go (except for a trigger upgrade). Adults shooting the new 10/22 TTR will want to add buttpad spacers as the gun ships with a very short 12 3/4″ length of pull from the factory.

Vortex Optics of Middleton, Wisconsin has introduced the impressive new Razor HD 5-20x50mm tactical scope. With HD objective glass, this new scope is very bright and very sharp. It also has a ton of vertical and horizontal adjustment. Advanced design and a fat, 35mm maintube give the Razor 5-20×50 a whopping 125 MOA (36 milrads) of total adjustment (combined above and below center) for both elevation and windage. 125 MOA of adjustment is huge. That’s enough vertical for ultra-long-range shooting with almost any modern cartridge.
Impressive APO and HD Glass on new 5-20×50 Razor
The optically-indexed lenses are precision-ground from XD optical glass and coated with Vortex’s XR coating for enhanced resolution, clarity, and edge-to-edge brightness. The Vortex also boast a multi-element apochromatic (APO) objective lens that virtually eliminates chromatic aberration across the entire field of view.
 Ranging is simplified with Vortex Optics’ proprietary new EBR-2 milrad reticle. Laser-etched and placed in the first focal plane, the reticle enlarges and shrinks with the target when zoomed so the scale remains constant at all magnifications. In addition, the subtensions on the EBR-2 milrad reticle match the 0.1 milrad turret clicks for simpler ranging and adjustments.
Vortex’s RZR (Rapid Zero Return) Zero Stop mechanism employs a rotational-blocking steel design. Vortex claims this patent-pending system is “mechanically more reliable and accurate than other systems that block the vertical movement of the turret”. The RZR Zero Stop delivers precise return to zero without the need to count clicks.
The 5-20x50mm Razor features waterproof/dustproof/shockproof construction and boasts a full 3.9″ of eye relief through the entire 5-20X range of magnification. This impressive new tactical scope has an MSRP of $2499.00, while “street price” is about two grand. For $1999.95, SWFA.com offers the 5-20×50 HD with 0.1 milrad clicks and EBR-2 reticle (item RZR551), or with 1/4 MOA clicks and EBR-1 reticle (item RZR550).
Vortex Optics and Unconditional Lifetime Warranty
You may not have heard about Vortex Optics yet, but this American-owned company is putting out some very good scopes these days. Vortex backs its products with its unconditional, transferable, lifetime warranty. That warranty is as good as it gets.

 We interviewed Chris Hodgdon of Hodgdon Powder Co. and learned some important information about the IMR’s new 8208 XBR powder. First Chris confirmed that ADI (Australian Defense Industries Ltd.) is the manufacturer. The powder is a very small extruded powder, similar to H322 in kernel size. That means it packs densely in a case and meters well in manual powder measures. As to burn rate, Chris stated that IMR 8208 XBR is “a tad slower than H4895.” Chris confirmed that the powder’s distinctive qualities are temp stability in an ultra-wide temperature range and a very broad accuracy window. Chris said: “Jim Carmichael found he could go up and down [significantly] in his charge weight and the group size didn’t vary.”
Hodgdon has already begun shipping IMR 8208 XBR to “OEM manufacturers” according to Chris, who said a major manufacturer will be loading the powder into .308 Win ammo and possibly other cartridges. Chris hopes to send AccurateShooter.com some of the new 8208 XBR powder for testing within two weeks. When will the powder be available to the general public? Chris couldn’t give a firm answer, but he stated “we hope to start shipping in January, 2010, prior to SHOT Show.”
IMR 8208 XBR Load Data Now Online
The Hodgdon Reloading Center site has been updated to include IMR 8208 XBR load data for 41 cartridges. Go to www.data.hodgdon.com and select “Cartridge Loads”. Then you’ll need to input the rifle cartridge of your choice. We quickly found IMR 8208 XBR loads for the .223 Rem, 22 PPC, 22-250, 6 PPC, 6mm BR, 6.5 Grendel, and .308 Win, and many other cartridges. NOTE: For most of these cartridges, the stated “max load” velocities were NOT particularly impressive. So, be aware, that this initial load data is pretty conservative.

One of our readers, Rafal Walczowski, revealed that programmers from Poland have developed ballistics software for cell phones. The new program, KABAL, should be able to operate in over 90% of programmable mobile phones. Rafal tells us: “Our idea was to develop software which could be used on the most common devices people carry all the time — mobile phones.” Current mobile ballistics programs require a separate device (such as a Windows PDA), or are limited to a single type of phone (e.g. the KAC program for the I-Phone). The Polish developers came up with a handier, more universal application: “We made software that should work on every device with JAVA MIDP.2.0. That should work for about 90-95% of the phones on the market. And, later, we will make a KABAL version that runs with older versions of JAVA.”
Rafal reports the KABAL Ballistics program for mobile phones has worked well in field tests: “The algorithm for our calculator was field-tested for 18 months at ranges up to 1076 meters. Many different calibers, rifles, and bullets were employed during testing. We are pleased with the results, even when compared to QuickTarget and Exbal programs. Our KABAL program often proved more accurate, especially for long-range calculations, whereas QuickTarget and Exbal could be too optimistic.”
English Version Coming Soon — and Free BETA Version Online
Rafal reports: “Several weeks ago we finished the Polish version of KABAL and we are selling it for mobile phones. We are now are working on an English-language version, which is currently in beta testing.” There is a free English test version that works in a PC browser. This includes a BC database, a bullet stability calculator, plus tooltips describing each field. You can try out the free online beta version by clicking the link below. Rabal adds: “We would highly appreciate any opinions/feedback about our software”.

October 3rd, 2009
 Hodgdon Powder Co. has unveiled a brand new powder, IMR 8208 XBR. From early reports, this is an exceptional new propellant that may change the way the game is played in short-range benchrest. According to Hodgdon, “IMR 8208 XBR is a remarkably advanced technology propellant” formulated for popular match, varmint and sniper rounds, including 223 Rem, 308 Win, 6mm PPC, 204 Ruger, 6mm BR, 22-250 Remington and similar calibers. We’re told the powder is being produced by ADI in Australia.
IMR 8208 XBR is Consistent in All Conditions
This short grain extruded rifle powder exhibits exceptional stability with virtually no change in velocity at temperatures ranging from -40 degrees F to 165+ degrees F. Lou Murdica, who helped develop this new powder, confirms that it is not temp-sensitive. Lou told us: “I have been shooting IMR 8208 XBR for over a year and I have done a lot of winning shooting it. One of the great things about this particular powder is, I always shoot the same load whether I shoot it in Florida or Phoenix AZ. I have never had to adjust for temperature or humidity.” That’s big news in the short-range BR game. Currently, most competitors must tailor their load to suit conditions.
IMR 8208 XBR is Already Winning Matches
Lou Murdica, one of the nation’s top BR shooters, won numerous matches with 8208 XBR in 2009, including the Heavy Varmint Grand Agg at the Cactus Classic. In August 2009, Jim Carmichel won the Heavy Varmint Grand Agg at the IBS Group Nationals. What is significant here is that Jim shot the exact same load of IMR 8208 XBR both days to win the event. That’s right–this powder requires far less “tuning” than most other powders currently used in short-range benchrest.
Product Development and Performance
Lou Murdica revealed some interesting facts about IMR 8208 XBR. Lou explained that the development team was initially trying to produce a propellant that would match the desireable characteristics of the “classic” T32 powder from the 1960s. In the process of developing a T-Powder clone, Lou says that the Hodgdon/IMR powder wizards came up with something even better: “We were originally pursuing a formula like T-Powder, but we came up with something a bit different. It was so good, and shot so well, that we didn’t want to lose it. It turned out that this stuff shot as well or better than the earlier T-clone mixtures and was incredibly stable.”
 Lou continued: “I’ve shot a lot of T-Powder and it is sensitive in certain way. I feel this new powder is equal to, if not better than, a T-Powder clone because 8208 XBR is not sensitive. I can shoot the same load, at any location, in any temperature or humidity. Additionally, and this is very important — the new powder is very forgiving. It has a very broad accuracy window. If you’re shooting 30.0 grains in a 6 PPC successfully, we found you could go down to 29.8, or up to 30.2 and the accuracy was still there. You won’t see a change in group size. It has a very wide and forgiving load window.”
[CAUTION: These charge weights may be excessive with your rifle and your bullets. Always start 10% low and work up.]
The new powder is versatile and has plenty of energy. Lou tells us “8208 XBR is a great powder. With a 6 PPC shooting 68-grainers, I can get up into the 3500 fps range. And the powder will work with larger cases too. I’ve tried it with success in a 6BR with 105s and I think it will work in a Dasher or 6 BRX. I also shot it in a 22BR successfully.”
Lou predicts that IMR 8208 XBR will have a big impact on the Benchrest game once it is widely available: “Once this powder gets in people’s hands I think you’re going to see GREAT things. It’s not finicky. It meters really well out of normal powder measures. It’s really stable. There are plusses all around. We’ll know within a year whether it becomes the powder to beat.”
Lou is no longer involved in the sale or distribution of IMR 8208 XBR: “I’m not in it any more. I have to buy my powder like everyone else.” But he encourages all BR shooters to give it a try: “The powder is fantastic. I have been telling everyone to go to your powder dealers and order it. Buy a jug and shoot it.”
Lou has high praise for the folks at Hodgdon: “You can’t say enough good things about Chris Hodgdon and Hodgdon’s willingness to develop this new powder. They’ve finally given us something we’ve really wanted and really needed. What they have done is great.”
Product Availability — IMR 8208 XBR in Short Supply until 2010
IMR 8208 XBR will be available in 1-lb canisters and 8-lb kegs in 2010. Hodgdon has produced limited quantities already, and you may be able to find some 8208 XBR at popular vendors, such as Powder Valley, in early January, 2010. You’ll need to call around to see who has it.
