7mm ultra mag vs 300 win mag ballistics

As an example, let’s take two rounds, both are 100gr, but one has a diameter of .100″ and the second has a diameter of .200″. Of course, it might also tell us that both are more than capable of doing the same thing efficiently and effectively. Before we get started, I have an administrative note: Some of the links below are affiliate links. The averages definitely lean towards the .300 WM rounds for higher momentum. :-) Either will drop game reliably at distance. We have also added an additional 1,000 yard marker for those who like to push their limits. Mag. Due to its advantage in case capacity, the .300 Win Mag has a noticeably flatter trajectory along with approximately 20% more energy than the .30-06 Springfield. Unfortunately, there is no single measurement that is going to convey to us a cartridge’s stopping power, but there are several factors that influence stopping power such as bullet energy, penetration, and bullet expansion. The fact that I have to nitpick the strengths and weakness of each cartridge like that really speaks to their overall effectiveness. The 7mm RM has a flatter trajectory throughout the bullet’s range, but the largest difference seen between the two cartridges is only 0.9 inches at the 400 yard mark. The case isbased off a .404 Jeffery Nitro Express by narrowing down the neck to fit a .308 (7.8mm) bullet. Secondly, ammunition and components for the 6.5-300 Weatherby Magnum are going to be more expensive than for the .26 Nosler.

While this cartridge has been and is still used in sharp shooting corners of the military, the majority of its action is found in the hunting world. Like most ballistic and other performance specs we have looked at between the 7mm Rem Mag vs .300 Win Mag, there is not a whole lot of difference between the two cartridges. This speed along with the sectional density is going to be more than enough to penetrate to and through vital organs of big bull elk and moose at long ranges. That introduction was, I’m guessing, retaliation against Remington’s 1962 release of its equally famous 7mm Remington Magnum. Maybe I’m a bit of a wimp, but when everything doesn’t go as planned, and you need to take an extra 10 or 15 shots at the range to get the new scope or new loads figured out, or verify your MPBR, that extra recoil can take a real toll. As I’ve stated many times: the 7mm Remington Magnum and .300 Winchester Magnum are both outstanding rifle cartridges. Though the averages give a slight advantage to the 7mm Rem Mag in flat trajectories, especially as it moves out to the 600 and 700 yards range, the two top performing rounds at each yardage marker was a 7mm RM and a .300 WM. The .308 Win and 7mm-08 Rem are also very good choices as general-purpose rounds and will remain so. While picking the most accurate cartridge of the two is a relatively contentious subject, most people agree that both the 7mm Mag and .300 Mag are capable of excellent accuracy. Both are celebrated by hunters worldwide, but which one of these classic .30-caliber cartridges will come out on top Weapons. The 7mm RUM is based on the .300 Remington Ultra Magnum (1999) which is in turn based on a grossly modified version of the unbelted 404 Jeffery’s case. We are looking at the bullet drop (inches) from the 50 to 300 yards with the firearm zeroed in at 100 yards. The recoil energy for these rounds was generated as we described earlier and used the same variables. Below, you will find the numbers for the larger data set. Glad you enjoyed the article Heine. Let’s take a look at the how the recoil energy between these two cartridges compare when we work with a larger data set. The shooting stops being fun at some point, and I don’t like that. Designers at Winchester during that timeframe could see what direction the wind was blowing and they began work on a .30 caliber cartridge built along the same lines as their other belted magnums. The 7mm RUM is really only a good option if you are shooting ultra long range. Also if Elk are ever a posibility I like the added energy at 1000 of the heavier 210 gr 300 bullet. The life of barrels for shooting a 7mm RUM is approximately 400-500 rounds due to erosion from gas, but can be extended further by waiting for the barrel to cool between shots and using cleaning out powder … Mag. Though both cartridges utilize .308″ bullets, the .300 Win Mag is also better suited for using heavier bullets in the 200-220 grain range than the .30-06. Book an incredible African safari hunt here. We are again seeing that both of these cartridges are performing very similarly. For the .300 Win Mag rounds, all of the them leave the muzzle with over 75lb/ft.s of momentum while all of the 7mm RM rounds are below the 70lb/ft.s mark. If you need a round that’s going to resist wind deflection and drag, both the 7mm RM and the .300 WM have options to get the job done. I’ve been told by more than a few experienced hunters that the 7mm bullet is too small to break thru the heavy bones of a large Elk. Mag.

The 300 WM produces significantly higher recoil energy almost 30% more. That is why you will see so many 300WM with muzzle breaks. But when hunting moose in Alaska I did go with a 300 WM for the bullet weight. Remington's decision to use a metric bullet may have been prompted by their past success with the 7 mm bore diameter. If you can make the shot and score an ethical kill on the game animal, go for it. 1 of 3 Go to page. It takes some range time to dial it in for a specific load, but once you have it dialed in, it is an outstanding flat shooting rifle for small and medium sized game at longer ranges than a 30-06.

Before we move on to the trajectories of these two cartridges, take a look at the average BCs of the larger sample size. In this next section, we are going to look at several sub-categories of stopping power. Both cartridges also have heavy enough bullets and the terminal ballistics to be used for larger game such as elk, moose, and more exotic game and still have a wide effective range. The sectional density correlates with the amount of penetration a bullet will have on the target, and since we are not looking at bullet types and designs in this article, we think the SD is a good means of comparison for two cartridges. The .300 Ultra Mag can fire the same weight bullet approximately 200-300fps faster than the .300 Win Mag. Both cartridges maintain supersonic speeds over a 500-yard range and will maintain that rating over several hundred more yards. Penetration is another component to a bullet’s stopping power that we want to address in this article. For the .300 Win Mag, our choice goes to the Nosler Trophy Grade AccuBond Long Range 190gr.

Sectional density is a measure of the ratio of the diameter of a projectile to its mass. We first notice that the caliber of bullets that the casings will accept are different. While we will not be graphing all of these rounds (that would be a nightmare for your eyes) we have calculated averages for both and will present those at the end of each section. Read ballistics comparisons on the two rounds but was wondering which one you guys prefer and why?
