RMR Bullets is a U.S.‐based company specializing in manufacture and sale of bullets, cases and reloading supplies. Their product lineup covers both pistol and rifle calibres, including popular handgun bullets like 9 mm (.355"), .357 Sig, .45 ACP and rifle calibres such as .224 (5.56 mm) and .308 (7.62×51) among others.
The company emphasises “in‐house” production of bullets (and some cases) at their facility in Lewiston, Idaho, USA — so many of their items are labelled “RMR In-House”. Their mission statement emphasises providing quality products, strong customer service, and competitive pricing.

In terms of bullet types, they offer Full Metal Jacket (FMJ) Round Nose (RN), Flat Nose (FN), Truncated Cone Flat Point (for match use), Heavy MatchWinner series, and Jacketed Hollow Point (JHP) variants (e.g., for self defence or specialised loads). For example, their 9 mm 147 gr Heavy MatchWinner FMJ Flat Point is marketed for sub-sonic and heavy‐weight 9 mm or .357 Sig shooting.
They also offer “Seconds” bullet lots (bullets with cosmetic or minor weight variances) at reduced prices, noting these are still shootable and made on the same machines.
Important user notes: some bullets have specific seating depth or OAL (Overall Length) requirements to chamber reliably in certain firearms; for instance the 9 mm 147 gr RMR FN requires ~1.10″ OAL in many handguns, and may present issues in pistols with very short leade (such as some Glock Gen 5 or CZ models).

About RMR load data on XXL Reloading
This page collects every RMR bullet we hold reloading data for, grouped by caliber and bullet weight. Each caliber and bullet combination links to a detail page with powder-by-powder load recipes: powder brand and type, start and maximum charge weight in grains and grams, case fill ratio, calculated peak chamber pressure, muzzle velocity and the barrel length the load was computed for.
Unlike a manufacturer's own tables, our RMR data is generated with an inner-ballistics engine across the full powder range, so you can compare many powders side by side for the same bullet instead of the handful a single load manual prints. Charge weights, pressures and velocities are modelled consistently, which makes cross-powder and cross-caliber comparison meaningful when you work up a load.
Use the caliber and bullet-weight filters above to narrow the list, switch to the Bullets tab to browse the RMR product range, and open any combination to see the full load table. All data is calculated reference data for experienced handloaders: always start at the minimum charge, work up carefully in your own rifle, and cross-check against current published data before firing.
