Nosler
Nosler Custom Brass for the 300 Remington SA Ultra Magnum delivers the consistency and quality that serious handloaders demand. If you're working up precision loads for a short-action magnum—whether for long-range hunting, precision rifle competition, or just dialing in your pet load—starting with properly prepped brass saves hours at the bench and gives you a genuine foundation for accuracy. Nosler's premium brass comes factory-ready to load, so you skip the tedious case prep work and get straight to the reloading press.
Each piece in this box of 25 has been through Nosler's rigorous prep protocol: chamfered and deburred case mouths, checked flash holes, precise full-length sizing, and trimming to spec. The brass is then weight-sorted to hold variation within ±0.5 grains—tight enough that you're not chasing case-weight variables when you're chasing velocity nodes. Hand inspection ensures dimensional standards are met, giving you consistent case walls and neck tension from round to round. That consistency translates directly into tighter groups and more reliable performance across multiple loadings.
Nosler brass is known for solid case life and reloadability without brittleness or premature failures. If you're tired of sorting and prepping bulk brass or dealing with inconsistent dimensions from the box, Custom Brass takes a real load off your reloading workflow and lets you focus on what matters: building accurate ammunition.
| Cartridge | 300 Remington SA Ultra Magnum (SAUM) |
| Brand | Nosler |
| Product Type | Premium Unprimed Rifle Brass |
| Quantity | 25 rounds |
| Weight Sorting Tolerance | ±0.5 grains |
| Condition | New, fully prepped |
Yes. Nosler Custom Brass arrives fully prepped—deburred, chamfered, sized, trimmed, and hand-inspected. You can begin loading immediately without additional case prep.
Each piece has been sorted so its weight falls within ±0.5 grains of all others in the lot. Uniform case weight reduces variables in powder burn and velocity, helping you achieve tighter shot groups and more consistent ballistics across your ammunition.
Nosler brass is engineered for multiple reloadings. The exact number depends on your load pressure and practices, but Nosler's quality materials and design support solid case life and reloadability without premature failures.
No. This is unprimed brass only. You'll need to supply primers, powder, and bullets to complete your loads.
