Consider Norma Powders for Large Cartridges
Can’t get H4350 or H4831sc? If you need slower-burning powders for your .260 Rem, .284 Win, 7mm WSM, or magnum caliber, consider Norma powders. While the popular Alliant and Hodgdon medium-to-slow burn-rate powders are still very hard to find, you can get similar Norma powders from many vendors right now, no waiting.

Norma 217 powder valleyPowder Valley has Norma 204, 217, MRP, and URP in stock. MidwayUSA.com has 204, 217, MRP, and URP in stock. MidsouthShootersSupply.com has Norma 204 in stock. The Lapua Burn Rate Chart (shown below) places URP in the burn range of H4350 and Vihtavuori N150, and Norma says “burning rate for URP is close to our 204 but on the quick side.” Norma 204 is slower than H4350 but a little faster than H4831sc. MRP is close to the original H4831. Download Chart as PDF.

Norma 217 does not show on the Lapua chart, but it is a good powder for the heavy magnums. Norma says that “Norma 217 is slightly slower than the discontinued MRP2. It was developed for the 30-378 Weatherby from start. Matches the .338 Norma Mag and .338 Lapua Mag perfect with heavy bullets. It is also a good candidate for [overbore cartridges] such as 7mm Rem Mag[.]“.
