Vihtavouri 20N29 for 50 BMG Powder 8 Lbs
For .50 BMG there are two special Vihtavuori reloading powders available: 24N41 and 20N29. They are, like N100 series, single base surface treated powders. Their burning rate is slower and grain size larger than that of the N100 series rifle reloading powders. The renewed relative burning rate of the 24N41 is 39 and that of the 20N29 respectively 36, when N110 is given the index 100, and therefore 24N41 is slightly faster burning than 20N29. There is reloading data available also for some other magnum rifle calibers with these powders and 20N29 has gained reputation also when used eg. in .338 Lapua Magnum and in .30-378 Weatherby Magnum.
