Does any one use IMR-4350 for their .308 loads? I know there are better choices for this round but I have 8 lbs. of this to use in something. Some of my load manuals list this powder for 150 and 165 grn bullets. What are your thoughts and experiences? Thanks
...I use IMR4350 for several rifles. Like he said, 243, 2506AI, although I like the slower powders for that, and in my 260AI, and in a couple 3006 loads. I think I even have a 22250 load for it. Just kidding, unless you really want to get rid of it. I imagine between what you'd want for it and the haz mat shipping, I could buy another 8 lb here.
If you are not trying to reach too far, why not try it behind 180grn bullets? That's where it appears to be reasonably effective.
I suspect you'll simply run out of case volume behind 165's with less than stellar velocities.(2650?) I use 75 grains behind 165's in my 300 win, and it does wonderfully.(~3130fps)
I'd simply fill your case with 4350 and measure the charge, squeeze a bullet on top, and sell me the rest when you decide it's boring at that loading.
