When discussing the 7mm Remington Ultra Magnum (RUM), it’s crucial to compare its ballistics and performance against similar cartridges, such as the 7mm Remington Magnum and .28 Nosler. Here’s what I’ve gathered:
Key Ballistics Numbers:
7mm RUM:
Velocity: Approximately 3,000 - 3,300 FPS
Energy: 3,200 - 3,600 ft-lbs
7mm Rem Magnum:
Velocity: Approximately 2,800 - 3,000 FPS
Energy: 2,700 - 3,000 ft-lbs
.28 Nosler:
Velocity: Approximately 3,000 - 3,300 FPS
Energy: 3,100 - 3,600 ft-lbs
Performance Highlights:
The 7mm RUM generally offers superior long-range performance due to its higher ballistic coefficients and energy retention compared to the 7mm Rem Mag.
Its optimal use shines in open country hunting where range and accuracy are crucial.
Larger powder capacity allows for heavier bullet options, which is beneficial when targeting larger game.
Practical Considerations:
Recoil can be significant, so it’s important to practice with it if you plan to use it for hunting.
Reloading for the 7mm RUM can be rewarding, allowing handloaders to maximize bullet performance according to their specific needs.
Overall, the 7mm RUM is an exceptional choice for those seeking high performance and versatility in various hunting scenarios. If anyone has experience with this cartridge or comparisons to others, I’d love to hear your thoughts!
The 7mm Rem Ultra Mag is revered for its flat trajectory and high velocity. Typically, it uses bullets ranging from 140 to 180 grains, with velocities exceeding 3,200 fps. This makes it a top choice for long-range hunting.
When you’re considering bullet weight, I’d argue that the 160-grain options balance velocity and energy very well, making them versatile for various hunting scenarios.
I totally agree! The 160-grain bullets have great ballistic coefficients, which help maintain their energy over distance. It’s a great option for anything from deer to elk.
What about the effects of barrel length on performance? I’ve heard that you can gain some extra velocity with a longer barrel, but how much does it really make a difference?
Great question! Typically, a longer barrel can increase velocity by about 50 fps per inch. So, going from a 20-inch to a 24-inch barrel can offer significant benefits.
For target shooting, the flatter trajectory of the 7mm Ultra Mag really shines. You can stretch it to 1,000 yards with the right load! Anyone here tried that?
Oh, definitely! Target shooting is where this caliber excels. Just make sure your optics can handle the distances, or you’ll end up playing hide and seek with your shots!
Absolutely! Even a slight wind can push your shot off target when shooting at longer ranges, especially valid with the 7mm Rem Ultra Mag. It’s worth practicing in varying conditions.
I think it’s also great for beginners under the right conditions. With low recoil compared to other magnums, it’s manageable for newer shooters, yet still provides enough power for larger game.
You make a good point, [quote=“pcarey, post:11, topic:1361”]it’s also great for beginners under the right conditions[/quote]
. But underestimating it can lead to trouble if someone isn’t prepared for the power.
I heard a joke the other day: why did the bullet get hired for the job? Because it had the right caliber! But in all seriousness, choosing the proper load is key for optimal performance.
Haha! Good one! But seriously, it’s crucial to match your bullet type to your game species. A lighter bullet may not have the same stopping power as a heavier one, especially on larger animals.
Has anyone used custom handloads with the 7mm Rem Ultra Mag? I find that you can tailor the specifications to really enhance performance for your specific needs.
Custom handloads can definitely optimize performance! I just recommend taking the time to really test them at the range before heading out into the field.
I’ve had great success using H1000 powder with the 7mm Rem Ultra Mag. It provides excellent velocity and accuracy. Anyone else have good experiences with this powder?
I’ve also used H1000, but I found IMR 7828 works better for me. It delivers good consistency, especially in colder weather. What’s your preferred bullet weight?
