The sixth edition of the Hornady Handbook of Cartridge Reloading shows that A grain Hornady bullet can be driven to a MV of fps by Note: The complete article about the.It was developed during the s as a high-powered, long-range cartridge for military snipers.

It was used in the War in Afghanistan and the Iraq War. As a result of this, it became more widely available. The loaded cartridge is British military issue overpressure. In addition to its military role, it is increasingly used by hunters and civilian long-range shooting enthusiasts. After preliminary experiments, a. One of the disadvantages of these old cartridge cases, which were intended for firing cordite charges instead of modern smokeless powderis the thickness of the sidewall just forward of the web.

During ignition, the cartridge's base, just forward of the bolt face, is not supported. Pressed by military deadlines RAI looked for another case producer and contacted Lapua of Finland in Subsequently, Lapua of Finland put this cartridge into limited production. The current. Lapua opted to redesign the. In the new case design, particular attention was directed toward thickening and metallurgically strengthening the case's web and sidewall immediately forward of the web.

In modern solid head cases, the hardness of the brass is the major factor that determines a case's pressure limit before undergoing plastic deformation.

Lapua tackled this problem by creating a hardness distribution ranging from the head and web hard to the mouth soft as well as a strengthened thicker case web and sidewall immediately forward of the web. Lapua also designed a The result was the. This was achieved by coupling a sensible case volume 7. Good factory loads, multiple projectile weights and factory special application ammunition are all available.

This cartridge is able to push a grain Bullets are available in a very wide range of designs and weights ranging from [9] to grains. SAAMI pressure level is 64, psi. The most common bullets loaded for the. This is from a 24" test barrel as compared to Figures would be higher if shot from a This is about twice as much as the recoil from an average. Strong recoil like this can be mitigated with the use of properly designed stocks and recoil pads. By comparison, this cartridge has less recoil than other more powerful.

When the. This is due in part to the bullet technology available today. Lighter bullets made today are able to hold together and penetrate deeper than heavier bullets of the past.

In North America, the. Apart from the larger deer species, the. It is often carried by fishermen, hunters and guides in Alaska and Canada for protection as encounters with these larger bear species can be common.

It has also been found to be effective against the big cats where hunting allows for the use of the cartridge. Due to the cartridge's popularity all North American rifle manufacturers offer rifles chambered in the. Almost all custom rifle makers in the United States and Canada produce.

Five cartridges that are currently viable do this, but I am not very interested in these, for reasons I explain in, The.

Versus the. I am more interested in comparing the performance of the. A thorough examination of ballistic data indicates that these two cartridges are capable of performance that closely approaches the. Whether looking at a particular cartridge on its own merits or comparing different cartridges, the logical place to start is with the ballistic data for available factory loaded commercial ammunition. There is a wealth of commercial ammo made for the. I found only one line of ammo for each of these: Hornady Superformance for the.

When A-Square standardized the. This simplified my comparison problem.


I used the Hornady Superformance line of. Hornady loads neither. Here are the comparisons, starting with muzzle velocity for each load. The total spread between highest and lowest MV for each bullet weight set is also noted. Muzzle velocity values are as stated by the manufacturers. There is nothing surprising about these data. However, the velocity spreads are not startling; all three cartridges drive the various weight bullets fast. The ballistic data for the. The data shows they fell slightly shy of the latter goal.

After muzzle velocity, one can generate reams of data on external ballistics, but to me there are only two variables that are important. Here are these data for the factory cartridges listed above.

Retained energy is calculated at the 25 yard increment nearest to the MPBR range of each load, using the ballistics calculator at www. The total spread between highest and lowest MPBR and retained energy for each bullet weight set is also noted. Despite the current long range shooting craze, I feel that all of these loads have more than adequate MPBRs for practical and ethical hunting purposes. To me, long range shooting at the rifle range and long range hunting shots in the field are two entirely different things, but that is a subject for another article.

Several factors combine to determine the terminal performance of a bullet on a live target. Every one of these loads carries over a ton of retained energy at maximum point blank range. There is really not much more that needs to be said. A few hundred ft. For instance, an elk hit in the vitals at yards with a grain bullet from a. Anyone who wants a high performance.

Elk,and piggies. If you like the rifle and it fits you and you are not sure the cartridge selection is perfect. That's not a surprise. None of them are. You can rationalize with math. For me, it is simple. Hogs are dangerous and higher power is necessary for your own safety, Elk are big and need a hard hit to take down too. A big heavy flat nose bullet would be ideal for either in my opinion with cast bullets. You might choose something else that you put more stock in.

It is reasonable to use foot pounds as a humane harvest level for both hogs and elk. I used that method to tailor a load down for my favorite rifle, a Colt Sauer. I never see Bear past yards where I hunt in high hardwoods and I tailored a load with a gr FNGC at fps and at yards I have over foot pounds left and I see that as a good safety margin for my distance with dangerous game like a pound charging Black Bear Just the math works for me, Try it with loads you are looking at in the and your variables with this free to use software: Handloads.

I'd feel safe to say this cartridge would be satisfactory on all game up too an including the Tyrannosaurus Rex. Emile Chartier I think each case, with its attendant capacity and pressure rating, has an optimum bore diameter. Based on that index, which is PURELY subjective and has no basis in fact, the '06 case is probably at its best with either.
