This ambition led to the development of the Ultra Magnum series, a family of cartridges designed for unparalleled power.
The development of the Ultra Magnum series was a response to the growing demand for more performance, particularly in the realm of long-range hunting and competitive shooting. The desire to deliver flatter trajectories, increased energy at extended ranges, and superior downrange performance fueled Remington’s engineers. The goal was to create a cartridge that could effectively take down large game at distances that were previously considered challenging, or provide a distinct advantage in long-range target shooting.
The 7mm RUM wasn’t just about incremental improvements; it represented a bold step forward. It was designed from the ground up to handle significantly more powder than existing 7mm cartridges, resulting in a substantial increase in velocity and energy. This new cartridge was larger, with a greater case capacity, and was built to provide a noticeable edge in various applications.
The creation of the 7mm RUM stemmed from a desire to leverage the existing popularity of the 7mm bullet diameter, which has a proven track record for both accuracy and terminal performance. The 7mm bullet is well-known for its high ballistic coefficient, which contributes to better downrange performance and wind resistance. Remington combined these existing benefits with a new approach to case design and powder capacity, birthing a cartridge that would quickly become a favorite among serious hunters and long-range shooters.
Understanding the Core: Performance and Specifications
To truly appreciate the 7mm RUM, we must examine its fundamental attributes. The cartridge’s dimensions are key to its impressive performance. The case is designed to hold a substantial amount of propellant, maximizing the potential for high velocities.
The cartridge typically uses bullets ranging from light bullets like the 140-grain variants to heavier ones reaching up to 180 grains or even slightly beyond. The selection of bullet weight can be crucial; lighter bullets tend to fly faster, with flatter trajectories, but heavier bullets possess more sectional density, delivering deeper penetration. This wide range of bullet choices allows hunters to fine-tune their load based on the game they pursue and the conditions they anticipate.
The 7mm RUM distinguishes itself with its raw velocity. Muzzle velocities commonly exceed 3,000 feet per second (fps) with some bullet weights, reaching speeds that offer unparalleled ballistic performance. This elevated speed translates directly to a flatter trajectory, giving the shooter a greater margin of error at longer ranges. It means less bullet drop, making it easier to hit a target at extended distances.
Energy is another critical aspect. The 7mm RUM delivers significant energy at the muzzle and maintains a substantial level of energy at long ranges. This power translates directly to the cartridge’s effectiveness in hunting. The combination of high velocity and substantial energy makes the 7mm RUM a powerful choice for taking down big game.
When compared to some other 7mm cartridges, the 7mm RUM stands apart. While the classic 7mm Remington Magnum is a great cartridge, the 7mm RUM offers a noticeable bump in power. This increase in power is most noticeable at extended ranges, where the 7mm RUM’s superior velocity and retained energy provide a clear advantage. This can be the critical difference when the shot must be taken far out.
The benefits of this cartridge are reflected when analyzing trajectory charts. The 7mm RUM has a very flat trajectory, minimizing bullet drop over the course of a long-range shot. This attribute reduces the need for holdover, making the shot placement much more predictable.
The Bright Side: Advantages That Make it Special
The 7mm Remington Ultra Magnum offers several clear advantages that make it an appealing choice for hunters and shooters. The first is its inherently high velocity and the resulting flat trajectory. With a flat trajectory, the shooter can aim with greater confidence, and the bullet will strike closer to the point of aim. This advantage simplifies the shot, decreasing the difficulty and increasing the probability of a successful hit.
It has exceptional energy, offering significant stopping power, and is suitable for bigger game. The energy delivered at the target is crucial, especially when pursuing large and tough animals. The 7mm RUM provides enough energy to efficiently dispatch big game at considerable distances.
Another strength lies in its versatility. It can be effectively used for various game animals. The cartridge offers hunters the possibility of pursuing different species with one reliable platform.
Finally, the 7mm RUM has demonstrated accuracy potential. With the right rifle, quality ammunition, and a skilled shooter, exceptional groups can be achieved at long ranges. This accuracy enhances the hunting experience and makes the cartridge useful for competitions.
The Other Side of the Coin: Considering the Drawbacks
While the 7mm Remington Ultra Magnum offers significant benefits, potential users should be aware of its downsides. One of the most noticeable is recoil. The high power generates a substantial kick. This recoil can be unpleasant for some shooters, and it can make it more difficult to maintain accurate shot placement. A well-designed rifle with a quality recoil pad can mitigate the effect, but it is still a consideration.
It is also true that it is a barrel burner. The large amount of powder burnt with each shot can erode the barrel over time, decreasing accuracy and necessitating barrel replacement. The speed at which the barrel wears depends on factors like how often you shoot the rifle, the powder being used, and the care that is taken to maintain it.
The cost must be factored in. Ammunition is often more expensive. Reloading is a popular choice and can help with this, but reloading equipment and components require an investment.
A further consideration is availability, with ammunition and components not as readily available as some more common cartridges. This can make it more difficult to acquire ammunition, particularly in rural areas.
Finally, barrel life can be shorter than with some cartridges. This is an important consideration, because barrel replacement adds to the overall cost.
