Originally developed as a powder for loading .22 rimfire cartridges, Vihtavuori 3N37 has a burn rate very similar to N350, and can be used for many of the same applications. As handgun shooters began to experiment loading with 3N37, they found that this fine-grained powder loaded evenly through measures and gave excellent results from a range of competitive cartridges used for USPSA and IPSC practical shooting disciplines
