It works quite nicely with 150/155 grain bullets in the 308 Win. and 300 Savage.
4320 has very small kernels so it goes smoothly through a powder measure.
Yep, good 308 powder.
Great in the '06 but ignored by many.
Denny.
Especially like it with an old DuPont/IMR Smokeless powders guide load with 150s.
6mm Remington with 100-grainers.
And with the 87 Hornady in my old 788.
Burned a few pounds of it with the 64 Powerpoint in my 223s as well.
I've long had a soft spot for IMR 4320.
