7mm RUM

7mm RUM ammo — the 7mm Remington Ultra Magnum — is one of the most powerful 7mm cartridges ever produced, a beltless ultra magnum that drives heavy 7mm bullets at blistering velocity for the longest-range big-game hunting. Built on Remington’s massive Ultra Magnum case, the 7mm RUM delivers more velocity and energy than the 7mm Rem Mag and even the 28 Nosler, making it a specialist’s choice for hunters who want maximum reach and authority on elk and large game at extreme distance. This page covers what it does and how it compares. It’s part of our full ammunition selection at Tatted Tacticals.

Tatted Tacticals stocks 7mm RUM from Nosler, Hornady, and Remington — premium long-range hunting loads with heavy high-BC bullets, by the box.

What the 7mm RUM Does

The 7mm RUM fires a 7mm (.284-inch) bullet at exceptional velocity — driving a 160-grain bullet well past 3,200 fps thanks to its enormous case capacity. Paired with high-BC bullets, it produces a very flat trajectory and tremendous retained energy at long range, capable of taking elk and large game at distances few cartridges reach. The trade-offs are substantial: heavy recoil, a loud report, and accelerated barrel wear from its large powder charges. It’s a dedicated long-range magnum for hunters who need maximum reach. Our 7mm RUM ballistic guide covers the data.

7mm RUM vs. Other 7mm Magnums

The 7mm RUM sits at the top of the 7mm power hierarchy, exceeding the 7mm Rem Mag and edging the 28 Nosler in case capacity and raw velocity. The newer 7mm PRC offers similar long-range performance with more efficiency and less recoil, which is why many modern hunters prefer it. The 7mm RUM remains the choice when maximum velocity and energy are the priority, recoil and barrel life notwithstanding. Standards follow SAAMI specifications.

Use premium high-BC hunting bullets and zero with your exact load. Federal law sets the minimum age for rifle ammunition at 18; some states and cities add restrictions, so per ATF guidance, confirm federal rules and review our ammunition shipping rules and state restrictions before ordering.

7mm RUM Ammo — Frequently Asked Questions

How powerful is the 7mm RUM?

The 7mm RUM is among the most powerful 7mm cartridges made, driving a 160-grain bullet past 3,200 fps with tremendous energy — exceeding the 7mm Rem Mag and matching or edging the 28 Nosler. It’s a true ultra magnum built for maximum velocity and long-range energy on big game. That power comes with heavy recoil and faster barrel wear, the cost of its performance.

Is the 7mm RUM good for elk?

Yes — it’s an excellent long-range elk cartridge. With premium high-BC bullets, the 7mm RUM delivers ample energy and a flat trajectory for elk at extended ranges, making it a favorite for hunters who take long shots in open country. As always, bullet selection and shot placement matter most; choose a quality controlled-expansion bullet for reliable performance on elk-sized game.

7mm RUM vs. 7mm PRC — which is better?

It depends on priorities. The 7mm RUM offers slightly more raw velocity from a larger case, while the newer 7mm PRC delivers similar long-range performance with better efficiency, less recoil, and longer barrel life. Many modern hunters prefer the 7mm PRC for its balance, while the 7mm RUM appeals to those wanting maximum velocity. Both are excellent long-range 7mm magnums.

Does the 7mm RUM burn out barrels quickly?

Yes, relatively. As an overbore ultra magnum burning large powder charges, the 7mm RUM wears barrel throats faster than standard cartridges, with barrel life often in the low thousands of rounds. For most hunters firing modest annual round counts, a barrel lasts many seasons. High-volume shooters should expect to rebarrel sooner than with efficient, milder cartridges.

Can you buy 7mm RUM ammo online?

Yes. In most U.S. states you can buy 7mm RUM online and have it shipped to your door, in premium hunting loads from Nosler, Hornady, and Remington. The minimum age for rifle ammunition is 18, and some states and municipalities add restrictions or shipping limits, so confirm your state and local laws before ordering.
