The .260 Remington and the 6.5×55 Swedish (aka 6,5x55mm SE) are both very popular cartridges with hunters and target shooters. The 6.5×55 has a long military heritage and a great record as a hunting round. The .260 Rem, essentially a .308 Win necked down to .264 caliber, is a more recent cartridge, but it grows in popularity every year, being one of the top cartridges for tactical/practical competitions. It offers better ballistics and less recoil than the parent .308 Win cartridge. In our Shooter’s Forum, respected UK gun writer Laurie Holland provided a good summary of the differences between the two chamberings. Laurie writes:
The 6.5×55 case has 6 or 7% more capacity than the .260s, even more in practice when both are loaded to standard COALs with heavy bullets, which sees them having to seated very deep in the .260 Rem using up quite a lot of powder capacity. So loaded up for reasonable pressures in modern actions, the 6.5×55 will give a bit more performance.
The issue for many is what action length is available or wanted, the 6.5×55 requiring a long action. So sniper rifle / tactical rifle competitors will go for the .260 Rem with the option of the many good short-bolt-throw designs around with detachable box magazines (DBMs). If a bit more performance is needed, the .260 AI (photo right) can yield another 100-150 fps velocity, depending on bullet weight.

If you really want to learn about long-range hunting, listen to a pro, a man like Nathan Foster who has spent a life-time in the field. Nathan has just released a new book: The Practical Guide to Long Range Hunting Cartridges. You can trust what Nathan says. He has spent decades in the wild, harvesting over 7500 head of game. Nathan’s richly-illustrated, 415-page resource guides you through the process of choosing the best cartridge and projectile(s) for your hunts. The book begins by explaining the key principles of of long-range hunting. Then Nathan examines the pros and cons of various cartridges so that the reader can select the best cartridge and projectile to get the job done.
Nathan is truly a hunting expert. Nathan has spent thousands of hours in the field and he knows the subject cold. Unlike some outdoor writers, Nathan doesn’t pull punches — he tells the unvarnished truth about what works and what doesn’t. Here’s what Nathan says about his new book:
After many months of writing, it is now done, 415 pages of research, each bullet repeat-tested in the field, my research scrutinized by veterinarian surgeons [and] industry peers. It was truly an immense undertaking.
For several years, I have received two types of email. The first question is which is the right rifle for me? The second question is which is the right cartridge? My first book dealt with the accurate rifle. This second book deals with long range hunting cartridge selection. I firmly believe that there has been a huge gap in education regarding optimal long range hunting cartridge performance. In many instances, both hunters and bullet manufacturers do not understand what’s required to achieve goals. Many times, the wrong tools are used for long range hunting. This book seeks to remedy these problems.
In the Practical Guide to Long Range Hunting Cartridges, I start with the fundamentals of game killing — but from the perspective of the long range hunter (also encountering close range shots). This section is not politically correct in any way, as after the study of anatomy, I explore worst case scenarios in as much depth as ideal shot placement.
The second section of the book is a study of projectile design. I wanted to get right down to the finer details of the long range hunting bullet in this section, exploring manufacturers, manufacturing techniques, and ways in which the end user can perform preliminary testing as well as bullet modifications.
The third section explains how to select a long range hunting cartridge. The system I have used here is based on a selection method I developed over the years to help clients worldwide. This method takes individual circumstances into consideration rather than a one size fits all approach. It is a system that relies on plain common sense based on research.
The fourth section of the book is the cartridge section. Cartridge information is presented in a set format with Pro/Con summary tables. In many instances I have included my own load notes. I have also included notes regarding how to approach close range shots with each of our long range cartridges.
Book Buyer Comment: “Nathan has ‘hit it out of the park’ with his 2nd book, The Practical Guide to Long Range Hunting Cartridges! This is definitely the ‘go-to’ manual for decision-making for hunters around the world. Where else can you fine such a wealth of information on bullet selection for a particular cartridge based on the weight of the animal you intend to pursue. This allows the hunter to make an educated decision on the best cartridge for a particular game species or to load that round, up or down, to cover a variety of game species in their location.” — Jim Moseley, North Carolina, USA

After much anticipation, we finally rolled out our latest project gun, a Bat-actioned 6-6.5×47/6.5×47 Lapua switch-barrel benchrest rifle. Equipped with two (2) Bartlein 30″ 5R barrels, the gun was designed to compete in a variety of disciplines: F-Class, Varmint Matches (Silhouette + Paper), and 600- and 1000-yard Benchrest.
The gun was built to a 17-lb. weight limit, with the goal of achieving the maximum possible accuracy with this pair of cartridges. We chose two identical, 30″ Bartlein barrels so we could evaluate the relative performance of the 6.5×47 and its necked-down 6mm version, holding as many variables constant as possible. Both barrels were chambered by ace gunsmith Mark King with tight-tolerance, no-turn necks.
. Sightron provided the SIII 8-32×56 30mm scope, shown mounted in Burris Signature Zee Rings.
The rifle, two years in the making, features top-of-the-line components. The action is a BAT multi-flat MB, with a +20MOA Weaver-style rail on top. As the action was originally intended to be used in an F-Class rifle, the loading port was enlarged at the BAT factory to load full-length .284 Winchester rounds.
The stock design is unique. It started as a Bruce Baer MB Tooley style, but we added some custom design upgrades. The sides of the fore-end are square (like a McMillan edge), and the underside of the fore-end has been relieved in the middle, creating two “rails”. The rear flat, on the underside of the buttstock, is 1.25″ wide, with a channel cut in the middle (to reduce drag, and to ensure that the bag tracks in the ears rather than on the center stitching.)
The stock was expertly inletted, pillar-bedded, and finished by Alex Sitman of Master Class Stocks. Alex put much time and effort into ensuring that the geometry was square throughout, with straight, parallel tracking surfaces. The BAT MB action has an extended front section, to allow for additional bedding surface. The MB action employs a three-action screw design. Sitman installed pillars for all three action screws then carefully bedded the entire action. Alex, one of the best stock-workers in the world, did a great job on this rifle.
Rifle Will Provide Load Data for New Cartridge Guide
This rifle was originally conceived as a match-grade test bed for the 6.5×47 Lapua cartridge and its wildcat cousin the 6-6.5×47. Jason Baney will test different powders and bullets in the rifle, to develop reliable load data for an upcoming 6.5×47/6-6.5×47 Cartridge Guide. And yes, we will be trying H4350, Reloder 17, and the relatively new Hodgdon Hybrid 100V. Jason will test a variety of flat-base and boat-tail bullets in both 6mm and 6.5mm.
Pet Loads Wanted for 6-6.5×47 and 6.5×47 Cartridge Guide
While Jason will generate load data for our planned 6-6.5×47/6.5×47 Cartridge Guide, we recognize that one rifle (even with two barrels) can’t provide all the key info. Each gun has its powder/bullet preferences, so we want to offer a broad sampling of load data for the new Cartridge Guide. That’s where you, our readers, can help.
If you shoot the 6-6.5×47 or 6.5×47 Lapua, and have developed some really great loads, share them with us. We can then include more data in our planned load charts. Send your “pet loads” to mailbox@6mmBR.com. Be sure to include: Powder Brand, Charge Weight, Primer Type, Bullet Brand and weight, and the OAL or known seating depth. We also request that you list the type of action, barrel length, and contour. Chron data is also important. Include the tested Muzzle Velocity, Extreme Spread (ES), and Standard Deviation (SD) if possible. It’s helpful if you can provide a short summary of your load, such as “Great 600-yard accuracy, near max, works best with light neck tension, low ES/SD.”
