Re: Who is using VihtaVuori 500 series powders
I don't know exactly what the burn rate of N550 is in a .30-60, but in a 22 caliber with lighter bullets, it seems to be slightly quicker than IMR 4350 but not quite as quick as H414. It should work nicely, and give you a little more velocity. It is double base though and seems to maybe be tougher on throats over the long haul. I know someone who has six pounds of it that would sell it for very cheap. It's all the same lot too. If interested, just post me.
If it's not far, it's boring.
