Home Forums Reloading Big Game Rifles What is IMR 4320 good for??

For me it has worked well in .22/250, .30/06, and even .222 Remington, where it is
a compressed load.


Burn rates for 4064, 4320, & 4895 seem very similar.

All worked well but IMR 4320 flows throw powder measures almost as well as ball powder, due to small grain size. IMR 4895 measured almost as well. 4064.

I think that newer powders and 4895 have taken the place that 4320 used to occupy.
