Anybody use IMR 4320 lately? Best use? Any rounds where it didn't work for you?

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.

I just put about 2 pounds of 3031 through a 3BR Redding....I finally figured its rhythm.
I can't help but thinking the IMR line as a misunderstood, under-appreciated series of useful powders.
I tend to think volume and less grains; with shortages and high demand, we've bought a few kegs of the old standbys and made them work well, like they always have.

I have used it in the 308 and the 300 savage.
It has also been tried in the 223 with 55 grain bullets.
It does fine work.

I have a 35 Whelen that is partial to IMR 4320 and the only powder/Barnes TTSX 140 grain bullet combination to give respectable groups in a 7x57.

Great in the '06 but ignored by many.

My best load in the 35 Whelen is 56 grains of 4320 behind any 250 grain bullet. Oddly enough it worked great in my 17 Remington as well. It is an excellent powder in a lot of applications and much overlooked.

It is the prefered powder by my .375-.416 Rem with G.S.Custom 265 HV bullets ( http://gscustom.co.za/). I get 3,050 feet per second and 1/2" groups. One time I got 3/4" at 300 yards and 5/16" for four shots at 100 yards.

I use it in my 6.5 and 7.7 jap rifles, it also works great in my 25-35 Winchester TC pistol.

Loaded most of a pound of it in my SIL's model 70 30-06 with 150 grain Hornady Interlocks. It shot real well for him.

I really like it in the 358 Win, I also loaded it in my 7mm-08 with both 100 gr an 140 grain bullets. I've got some 270 Win loaded with 110 gr Sierras and IMR 4320. It's also on the list for the 300 Sav. when the current supply of IMR 4895 loaded rounds gets low.
And I may give it a whirl in the 30-06 eventually.
It would be my choice if I had to pick one powder for all my uses.

With the 130 gr Hornady out of the .30-06, IMR4320 is the best powder I've found for good accuracy at top velocity. It's also my favorite powder behind the 150 gr bullets out of the same cartridge.
Other favorite pairings are: 50 gr Nosler BT and 52 gr Sierra HP in the .22-250. 75 gr Hornady HP in .243 Win. 120 gr Hornady SP in the 7x57 and 7mm-08. 130 gr Speer SPBT in the 7mm-08. 170 gr Hornady FP in the .30-30.
Although it is technically a stick powder, 4320 has the shortest kernel length in the IMR series, so it meters almost as nicely as a ball powder through your powder measure.
I was hoarding when hoarding wasn't cool.

My Go-To for 338-06 from 200-225s, should be worth trials in 7/08 - 120 loads and 260 - 85-100s.

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.

This is a powder I haven't used in quite awhile. If my memory is correct the burn rate is very similar to R15 of which I now use a lot. I know it was used in my 7-08 and my 220 Swift. I think it was usable but not memorable.
