Imr 4320

It is a shame if it's gone. I am down to 4 lbs but it is great in the medium bores.

Richhodg66 Do you mind sharing the charges and the boolit weight for your .358? I have some and was wondering how it would do with cast. I've used it for a maximum load with 225 grain Sierra which worked very well.

I used 40 grains and a tuft of dacron pillow filling and the NOE clone of the RCBS 200 grain flat point designed for the .35 Remington. Lee makes that bullet in a six cavity now, if I were to do it again, I'd buy one of those, I think.

Too bad. I found it to be excellent in quite a few things. Didn't have data for it, but when I got this 6.5 Creedmoor it seemed about the right stuff for it with 120 grain bullets and it was, amazing accuracy. Interpolated data from the 4064 data I had.

I have two or three pounds of it, and started experimenting with it and the 311466 in my .308 target gun. I seem to be on to something. It was also good with cast deer loads in my .358 and .32 Special.

What's with all the powder discontinuing these days? The industry seems to be introducing new ones, I have my doubts they're gonna perform any better.

You happen to have data for 4320 for the 6.5 Bleedmoor? I went through my old stash and I have 7 lbs of it and would like to put it to good use in something besides my .308. I'm using 140 gn bthp in the CM

It burns very closely to IMR 4064 which I did have data for, I just did a little interpolation and went from there. Worked fin, accuracy good, primers looked great, no sticky extraction and the deer never knew any different.
