What This Peterson RUM Brass Is and Who It Is For

The 7mm Remington Ultra Magnum was introduced by Remington in 2001 as a powerful, accurate long range round. From a 26 inch barrel it can reach roughly 3,450 fps with 140 grain bullets, 3,275 fps with 160 to 162 grain bullets, and 3,175 fps with 175 to 180 grain bullets. This brass is for the long range hunter and precision shooter who wants match grade cases behind those velocities.

Peterson Cartridge is trusted by shooters worldwide for precision, which is why this Peterson RUM Brass is a favorite among handloaders who refuse to compromise on case quality.

Specifications Worth Knowing

Each package holds 25 rounds of new, unprimed 7mm Remington Ultra Magnum brass. Because the RUM is a large, high velocity case, uniform capacity and headspace are essential for controlling pressure and velocity, and Peterson builds its brass to deliver exactly that. The listed velocities come from a 26 inch barrel and show why handloaders reach for this cartridge when they need reach. This is component brass and not loaded ammunition, so you supply the primers, powder, and 7mm bullets.

Practical Use, Care, and Compatibility

Full length size for your chamber, trim to a uniform length, and inspect the case head and shoulder after each firing given the pressures involved. Careful prep helps this Peterson RUM Brass hit your target every time and last through multiple reloads. It fits any rifle correctly chambered for the 7mm Remington Ultra Magnum.

Reaching Out with the 7mm RUM

The 7mm Remington Ultra Magnum was designed to be one of the flattest, hardest hitting 7mm cartridges available, and the velocities it produces put it firmly in extreme range territory. That performance only reaches its potential with brass that can hold consistent capacity under heavy charges.

Long range hunters value the RUM because it carries energy and defies wind far downrange, turning a difficult cross canyon shot into a manageable one.

Load Development and Long Term Value

Because the RUM is overbore, treat load development methodically, working up in small steps and letting a chronograph confirm your velocity spread before you trust a load at distance. Full length sizing keeps feeding reliable, and careful case inspection protects you from the stresses of a large, fast cartridge.

Match grade brass is the kind of investment that pays back in tighter groups and fewer fliers, and buying enough for a season keeps your ammunition on one consistent standard.

Ordering, Care, and Value

Check your twenty five cases when they arrive and store them in a dry, labeled container so a matched long range lot stays together. Clean, dry brass keeps for years, letting you develop loads methodically. With an overbore magnum, quality brass is money well spent, since it holds consistent capacity under heavy charges and helps deliver the tight velocity spreads that keep you on target far downrange. Building your own also lets you exploit the RUM’s full potential with premium high ballistic coefficient bullets.

For the long range 7mm shooter, this Peterson RUM Brass is a precision foundation. Ships direct to your door, no FFL required.
