2008年2月15日 · With the current powder availability I've decided to get rid of all old stock, partial cans etc. I found a few old metal IMR 4320 cans and decided to burn it up. .223, 6 XC (light bullets) .308, .30-06 what do you suggest?

2009年3月30日 · Re: IMR 4320 - .223 I guess a lot depends upon the measure. I ran some tests with a Redding, a Lyman, and a Dillon. With 4895 or Varget they all were within +/- .2 gr. With RL 19, the Redding and Lyman were the same but the Dillon would bridge about 3 time out of 5. Interesting, but frustrating.

2011年3月29日 · IMR 4320 is an overlooked powder with today's 308 Winchester shooters. IMR 4320 has short kernels and meters well. It's a great substitute powders when other, more popular powders are difficult to find. It's slightly slower than 4064 …

2013年7月18日 · IMR 4320 is a sleeper. Our (Navy Team) LR load for the Mk2-1 match rifles (308 M1) was Sierra 190 grain MK with 4320. It was definitely a kick-butt load at 600 and 1000. Joe Sopko (also USN team retired) used the old Navy load tweaked for his own rifles to win the Porter and Atkins trophies ~some years ago.

2013年4月16日 · Does anyone have any load data for IMR 4320 and the 260 Rem. I'm putting together a new rifle in 260, never loaded for it before. With H4350 impossible to find right now, I need to use what I've got available. I have Varget and IMR 4320 on hand. I'm looking at ordering some Lapua Scenar 139s, Berger 140s, Hornady 123 SST, and Barnes 127s to try ...

2009年11月9日 · On my burn rate chart, IMR 4198 is the fastest, considerably faster than your fav 4064. Then comes 3031, still faster by a good margin. Then comes your 4064, and finally IMR 4320 which is immediately below Varget on the burn rate chart. Good luck.

2010年3月31日 · Re: Hodgdon 4350 vs. IMR 4350 Yes. The H4350 is a temp insenstive powder. From winter time to summer time, you will notice a velocity/pressure change in your load with some of the IMR powders. I love the IMR powders, especially IMR4350. But a hot/fast load developed in the winter time will be a HOT load in the summer time.

Read couple articles lately regarding burn rate and M14's. One said use nothing slower than 4064 EVER, the other said use nothing slower than 4320.
