In our Forum recently, there was a discussion about “improved” cartridges based on the .243 Winchester parent case. One popular such cartridge is the Super LR, a 30° long-necked wildcat. The 6mm Super LR was developed by Robert Whitley, who wanted something similar to the 6XC, but with “more boiler room” to push the 115-grain bullets comfortably at 2950-3050 fps.
To illustrate the Super LR for interested readers, we dug into our archives and found a report on a 6mm Super LR varmint rifle belonging to Barry O. (aka “TheBlueEyedBear”), a long-time AccurateShooter Forum member. A few years back, Barry put together an impressive 6mm Super LR long-range varminter on a BAT SV action. Barry actually sourced many of the components for this rifle through our AccurateShooter Forum Free Classifieds.

The Richard Franklin walnut LowRider stock (above) for Barry’s rifle came from fellow Forum member “Preacher”, who also did most of the metal work. The gun is chambered as a 6mm Super LR.
6mm Super LR Cartridge Design and Loading Advice by Robert Whitley, AR-X Enterprises
Conceptually, the 6mm Super LR is like a long-bodied 6XC (case body about .120″ longer). The Super LR has a long neck (.321″ vs. the .263″ long neck of the parent .243 Winchester case). The Super LR also has a 30° shoulder angle vs. the 20° shoulder angle of the .243 Winchester parent case. The Super LR has about 54 grains of H20 capacity, compared to 55 grains for the .243 Win and 49 grains H20 for the 6XC.
The Super LR has sufficient case capacity to shoot the 115gr 6mm bullets in the 2950 – 3000 fps range without being “on the edge” of maximum pressure. If you do not need to run sustained fire in long strings, you can “hot rod” things more. Testing has shown that the Super LR can run the 115s up around 3100 fps without issues. With the 105-108 grain 6mm bullets, the 6mm Super LR can push them up in the 3150-3200 fps range with the right powders. In addition, if you like to shoot the 105-108 grain bullets close to the lands, or engaging the lands, the Super LR cartridge case neck is long enough to give most of them a good bearing surface purchase, even if the chamber is throated for the 115gr bullets. That gives the 6mm Super LR cartridge great versatility.
The 30° shoulder angle of the 6mm Super LR is another good feature of the Super LR. Not only does it help to avoid the throat-torching effect that people associate with the .243 Winchester (because of the .243’s short neck and 20° shoulder angle), but the 30° shoulder angle has also been a hallmark of some very accurate cartridges such as the 6 PPC, 6mm BR, 6XC, and 6.5 x 47, to name a few.
The 6mm Super LR wildcat is easy to make. Robert Whitley figured out how to reform domestic .243 Win brass with one simple pass through a Redding 6mm Super LR full-length sizing die. Robert has commissioned these dies from Redding. Call Robert at (215) 348-8789 to order.Learn more about the 6mm Super LR on Whitley’s www.6mmAR.com website.
Way to go Team USA! The American F-Class squad won the prestigious Creedmoor Cup competition held June 28-29 at the Midlands National Shooting Centre in Tullamore, Ireland. This is a competition with a rich history, going back to the original Challenge Match in 1874 between American and Irish Teams in Creedmoor, New York. (Read Match History)

Phil Kelley wrote: “I never knew when planning for this trip the wonderful history that is the Creedmoor Cup, Ireland and U.S. rifle competition, and the hunger of the Irish for freedom. It is one of many things that has made this trip so enjoyable. J.P. Craven [opened] the Creedmoor competition with John Sigler, previous President of the NRA. John had the honor of the first shot with a rifle used to help gain Irish independence. The Irish, like Americans, have a rich history that ties the rifle and independence together. It has been an honor to be part of this event, with each and every individual that is part of it.”

If you’re hunting in California, you better start using lead-free ammo. Starting July 1, 2015, “certified” non-lead ammunition will be required when hunting on all California Department of Fish and Wildlife (CDFW) lands and for all Nelson bighorn sheep hunts anywhere in the state.
CDFW reminds hunters who plan to hunt bighorn sheep or at any CDFW wildlife area or ecological reserve to acquire nonlead ammunition. California’s bureaucrats also state: “Hunters are also encouraged to practice shooting nonlead ammunition to make sure firearms are sighted-in properly and shoot accurately with nonlead ammunition. Nonlead ammunition for some firearm calibers may be in short supply so hunters should plan accordingly.”
Why is lead-free ammo now required? Thank the California Legislature. In October 2013, Assembly Bill 711 was signed into law requiring the phase-out of lead ammunition for hunting anywhere in the state by July 1, 2019. This is the 2015 phase, which applies to CDFW lands and Bighorn sheep hunts. The restrictions will become tougher each year, with a complete ban going into effect in four years.

Do you know the actual BC (Ballistic Coefficient) of your rimfire ammunition? Well Applied Ballisitics will soon have answers for you. Bryan Litz and his team of testers have been working on a Herculean project. They’ve been testing over fifty types of .22 LR ammo, using five different twist-rate barrels.
Here’s something that will teach unwanted guests some “table manners”. We’ve seen handguns hidden in books, and stowed behind faux baseboard vents, but this hand-crafted, slide-open table takes the cake. We doubt that anyone could sit down at this table and suspect that a shotgun, scoped rifle, two pistols and a knife were stored securely inside. There’s an arsenal hiding in there!
To access the guns under the sliding table-top, first you flip down a wood trap-door on the side. That exposes a key-lock which unlatches the interleaved left and right table segments. These slide open horizontally on metal tracks, exposing the full arsenal underneath. This “table vault” is a very clever design, built with fine craftsmanship. You can purchase this table from the maker for $1499.00.
Table Description
This table has a secret latch which pops down. Behind it is a deadbolt (or Kevo enabled Bluetooth lock). Once unlocked the table slides open toe reveal your valuables and/or guns. The table comes with a piece of blank white foam you can customize for whatever you would like to put inside.

The NSSF has posted a video featuring Bryan Litz of Applied Ballistics. Bryan also serves as Chief Ballistician for Berger Bullets and ABM Ammo. In this short video, Bryan explains the importance of ballistics for precision shooting at long range. Bryan covers key elements — drop, wind drift, angle correction and more. And Bryan also explains the key difference between Accuracy and Precision.
Varminter.com recently released a First Hunt Report on the new Savage A17 rifle. Savage’s new semi-auto .17 HMR has caused quite a stir. Accurate and affordable, the Savage A17 is also the first .17 HMR to feature a delayed blow-back action. We think the A17 may be the most important new rimfire rifle of 2015, so we were pleased to see that Eric Mayer, Editor of Varminter.com, put the new semi-auto Savage through its paces.
Mayer wanted to see how the new Savage would perform, accuracy-wise, and he also wanted to see how the A17 fared in the field. Mayer achieved one-MOA accuracy with the Savage A17 using the latest CCI-brand ammo, and he demonstrated the A17 is wickedly effective on ground squirrels. Here are some highlights from Varminter.com’s Savage A17 First Hunt Report:
McMillan has developed a new stock for F-TR competition. The front half is like a prone stock while the rear section has a straight underside (toe) section for smooth tracking in the rear bag. This stock appears to be designed for hard-holding, with a vertical grip and a fairly tall adjustable cheekpiece. The stock weighs just five pounds complete with adjusting hardware, so F-TR rigs built with this new stock should “make weight” easily. (The F-TR limit is 8.25kg or 18.188 pounds including bipod.)
Paul Phillips of Team Sinclair revealed the new McMillan stock on his Facebook page. Paul reports: “McMillan has been a leader in the industry for 40 years. I can’t thank the McMillan family enough for all they have done for our Military, Law Enforcement and Competitive shooting communities. Kelly McMillan and Team Sinclair worked together on what stock profile and features would be the best for FTR competition and this is what came out of the oven. Kelly also came up with some strong, super-light hardware that put the entire weight of the finished stock after bedding at 5 pounds even.
After Alex Sitman from Masterclass Stocks bedded my new stock, he told me that this new stock design is a true work of art and will fill a huge void in F-TR. Derek Rodgers set the current 1000-Yard F-TR record, 200-12X, with a McMillan prone-style stock. Team Sinclair holds the current 1000-Yard Team Record, 792-38X, and McMillan also contributed to that. McMillan [helps sponsor] the USA F-TR Team and Team Sinclair. Team USA will also be using these stocks in the upcoming 2017 World Championships hosted in Ottawa, Canada.”
Making Weight in F-TR — Every Ounce Counts
One Facebook reader asked why the new F-TR stock was so light. Here is Paul’s response:
Question: Paul, 5 pounds seems a little light. My Anschutz [stock] is heavier. Wouldn’t you want a heavier stock for stability, particularly for long range shooting?
Answer: It’s a fine line making an 18.18-pound weight limit. We need longer barrels to get the velocity to push 185- and 200-grain bullets. We also have a scope and bipod that add weight. It’s a balancing act. As I mentioned before, the current National record is with the same weight McMillan prone stock, just different profile. It works.
Forum member Jacob spotted this simple, but effective set of scope ring inserts on the Brownells’ Website. With these inserts, you can use a scope with 1″-diameter body in 30mm rings. Non-marring, matte black Delrin sleeves surround the scope tube so it can fit larger-diameter rings. Each sleeve comes in two parts for easy installation around your scope tube. Ring Reducers are sold as front/rear kits. Cost is $14.99 for the 30mm to 1″ ring adapters, item 084-000-091.
Note: These Brownells units simply function as plastic bushings. Unlike Burris Signature Ring inserts, they do not allow you to “pre-load” windage or elevation. If your rings are misaligned, the Brownells Ring Reducers won’t correct that problem.
