I used when I had a 220 swift and it shot great with a 52 gr bullet but rarely is it ever mentioned here on the "Fire".

For me it has worked well in .22/250, .30/06, and even .222 Remington, where it is a compressed load.
Burn rates for 4064, 4320, & 4895 seem very similar.
All worked well but IMR 4320 flows throw powder measures almost as well as ball powder, due to small grain size. IMR 4895 measured almost as well. 4064.
I think that newer powders and 4895 have taken the place that 4320 used to occupy.

58 grains 4320 under a 150 in my tikka 300 win mag makes a fun reduced load that shoots sub moa. Does about 2780 fps and is PERFECT for brush hunting whitetail here in Wis where shots are rare over 100 yds.

It works great, when nothing else I tried would, in my 243 with 100gr Nosler Solid Bases.

Best powder I've ever tried in .350 Rem Mag and 8x57. I expect it would work as well in .35 Whelen and also in .375 H&H.

It is a very good powder in the 35 Whelen. I believe it can be considered the first "short cut" powder, as it had the shortest grain in the original family of IMR powders. I think one of the 2006 issues of Handloader had a write up on 4320.

It was by ar the best in the .22-250 with the 55 Nosler. Typcally he accuracy was five shots at 100 yards about 5/8". The velocity averaged 3,775 feet per second.
It is the powder of choice for my .375-.416 Rem with 265 G.S. Customs at 3,055, 260 Noslers at 3,000 or 270 TSXs at 2,950. Depending on which bullet and how I am doing that day the groups range from a best of 1/16" at 100 yards with the G.S. Customs to 1 1/2" at 100 with the TSXs. I shot three groups the other day with the Noslers at 300 yards. Two of the groups were 3 3/8" and one was 3 5/8".

IMR 4320 is a great powder. My first "love affair" with it began with 150 BTs in 30-06 - loaded to max according to IMR Reloader's Guide. THe 358 Win shoots the 225 Sierra GK into tiny little groups with 4320 and about as fast as it can safely be pushed in that case. A 6mm I had loved 4320 with the 87 grain Hornady. In recent years I've burned more pounds of 4320 to push the 64 grain Power Point through the barrel of my 223. It is a really excellent, if somewhat neglected powder.
Truth and ultimate worth are not decided by democratic principles nor by the wallets of the people. Unfortunately it is the wallet which ultimately decides what we have or don't though. Long live 4320 anyway!

It is a tack driver in a 223 with a charge of 27.5 grains and a 55 grain bullet....

34.0 grains of 4320, with 52 grain bullets in a 22-250 was THE load years ago.

It's funny. I have a copy of a book titled "Propellant Profiles" which I consider an invaluable resource, partly because it's a bit dated and I often get questions about some old powder or other.
But in the review of 4320, the writer damned it with faint praise. His analysis showed that 4320 seldom produced peak velocities nor the tightest groups, but that it was a solid if unspectacular performer in many rounds. Ho hum.
I avoided using any 4320 for years because of that article. Until I started doing my own bookcrawling. It turns out that while 4320 does not produce top velocities in many rounds, it is off by only a very few feet per second - not enough to matter. Many loads were reported with second-place accuracy, and again, not enough behind to matter. Hmmmmm, thought I.
Bought a can. Loved the way it flowed and how charges were nearly identical. Confirmed that it delivers very respectable speeds and darn pretty groups in every round I stuffed with it, from 223 through 7-30 Waters to 308. Hmmmmm again, thought I.
Now, that dark green can has an honored place on my shelf. It's a keeper.

About a year or two ago I asked in the reloading section if IMR 4320 had become a forgotten powder.Recieved many positive replies if I remember correctly.Always had great results using it in my '06.
Certainly it has has fallen by the wayside for some but it is a great powder that has fallen out of favor not by any shortcomings but by the the introduction of newer and more versatile propellants.

I will be hunting with it this week in my 405WCF behind a 300gr Hornady. It produces 1 1/2" groups @ 100yds (as good as I can shoot with a peep) from my Win'95 at a little over 2200fps.

IMR 4320 delivered the most accurate load according to Barnes when used with a 200 grain TSX in the .325 WSM. I just loaded some up, but I dont have a scope for the gun yet. Results pending!

I use it in my .270 Weatherby Mark V & Swift Sirroco's 5 shot covered by dime. I also used it with .257 Weatherby Vanguard, 75 grain V- Max for 3 shot 1 hole group back to back, Then went south, ? if dirty barrel, I just can't seem to get consistent 75 grain v-max with RL22, the 4320 was the best, am out of 75 V-maxs so back to the TXS 115 - Load was with RL 22 but am going to work up 4320. ? if .257 Roy is just not really a varmit gun ya know. Barrels get too hot in summer
Use it 22-250 50 gr. or 55 gr. V-max, 36 grains or 4320 bug holes. It is hard to find load data excpet in old books.
