IMR 4320

[possum1]

Is there anyone using IMR 4320 ? Just curious, I'm getting good accuracy with my .223 and .243. Don't have a chrono, 53gr.223 show's in the book 2900-3200 vel. 70gr .243 show's 3300-3500 vel. any feed-back welcome.

I use it in my 223. Get around 3100 with 52's with .3 groups.

Thank's EF, just wanted to know the speed was there.

I'm using 4320 in .17 Rem. with 30gr. Berger and 23.7gr. 4320, around 3800 fps. Groundhog deadly. Quick

I use it in my .308 Win. I found a skeet range that had 16 lbs sitting on the counter. They sold it all too me for $10 a lb. That was last year..... still working on it. I also use in my TC Encore's ..... .308, 6.5 Sweede, 6.5 Bench Rest Mag (6.5 x 30-30).

WOW....Deal.

Best powders I've found for the .308 was Varget. I've tried bunches of others and always came back to Varget....FWIW.

For my 6.5 Swede (Modern action Savage) RL-22....one hole every time with both the Berger 140gr. VLD, and the 120gr. Barnes Triple-X. The Swede is just a wonderful cartridge. Same or better downrange energy as the .308 and nowhere near the recoil. Again.....FWIW.
