Based on the .300 Remington Ultra Magnum (R.U.M). The 7MM (R.U.M) was created to meet the need for ultra-high velocity long-range shooting. Although the 7MM (R.U.M) has enthusiast, those shooters normally choose a different caliber based on the short barrel life. It doesn’t matter what rifle a person utilizes, at some point it will encounter problems with; too much energy, wear and tear, stress and the barrels capacity of handling the caliber.

Both projectiles seem to have great performance with long range and a great Ballistic Coefficient (B.C). What the hunter wants to avoid is choosing a projectile that will produce a slow killing and lack of shock round that will lose energy on impact. This will cause the animal to be conscious while injured and run farther
