Home Forums Hunting & Shooting Ask The Gunwriters IMR 4320

gnoahhh

I'm similar but diff powder.

I ONLY ever bought ONE (1) pound of 3031. It is too fast burning for any cartridge I ever loaded.

I bought and used several pounds of 4320 for my 35 Whelen. My understanding of its burning rate is
between 4064 - 4320 - 4350. I have wondered if I should have tried to find out how close to 4350 it is/was.

Oh Well. I'm sad to see it go but I won't have a void.

It is one common powder that I never got around to using - always seemed to be too fast for my applications.

I look at newer "improved" powders the same as I looked at Ethanol replacing Pure Gas....B. S. no matter what they tell me....

My biggest used lists of powders are/Were... SR 4759, IMR 4198, 3031, 4064, IMR 4895, to a less extent 4320 but always have kept 4 lbs or so on the shelf...After IMR powders, My preference was with Alliant Powders...probably because they were out of Radford VA, near my home roots from the last 200 plus years...

of course, I also prefer Federal brass and primers living near Anoka MN for 15 years...

Use to try all the new stuff, but finally found myself using old school stuff the most, stuff that had been around longer than me.. it worked then and its still works just fine now...solid predictable performers...guess I'll keep using the ones I can, until the Good Lord discontinues ME...

Guess bottom line, I just don't see what's so great and appealing about "Change",,,,,

Guess I better start looking for a couple of 8 pounders of 3031....got the heads up when they were discontinuing SR 4759, so I picked up four 8 pounders of it on sale...cheap... I've been reconnecting with the accuracy 3031 returns...

been working with the 6.5 Grendal lately, which I enjoy... just brought home how much the average cost of 6.5 mm has gone up and the old standys are all being or have been discontinued...got a 6mm ARC barrel on the way also...4350 and such really don't work so good in these cartridges...nor the 223s, or 22.250s...

heck, last couple of months, going over to the range and target shooting with a heavy barrel 223, I've been having a blast with the accuracy of Unique in a 223 case.. shooting 40 to 80 rounds in an hour or two...doesn't really heat up the barrel very much in the long run.. a pound of it lasts a long time... 4 pound container, lasts a really long time.. the 8 pounder even more so...

each does a good job of plinking at 200 yrds at targets the max range of that particular shorter range... everyone thinks they need the far range ( out to 600) to zero their rifle for 50 yds black tail hunting... those big 90 to 100 pounder Blacktails....

like everything.... vendors want to max out the cost of everything.. .driven by their accountants.. Abe Horowitz

IMR4320 isn't nearly as slow-burning as IMR4350, and in fact is almost identical in burn-rate to IMR4064. You can find this out easily by looking at Hodgdon's on-line data. Rarely will maximum charges of 4320 and 4064 vary more than a grain in the same application, and often they'll be even closer.

Thanks You Sir:

The only rifle I ever used 4320 in was the 35 Wh.

4064 was one of my FIRST powders BECAUSE JOC used 52/52.5 grs of it in 06 with 150 gr bullets.

Also 49 grs of it in 270 with 130s. I'd guess that DATES myself, huh ? lol

I appreciate this info from you because of your experience with many more rifles/cartridges/powders than I have.
I'm far from a newbee but I'm not in the BIZ.

THAT IS GOOD NEWS for 35 W shooters -- 4064 is close to 4320 ! I'd like to have known that then.
I also know there are newer powders some are using in the Whelen but I'm not sure they are better. ???

Thnx Again

When I started loading for the 35 Whelen velocity pressure levels were held to 2600 fps for 225 gr bullets. The 225 NPT has long been my goto bullet in the Whelen, guy can argue the 200's or 250 s for this or that I don't care, I use the 225 gr NPT on everything that needs whelenizing. Flat works started at 2600 fps with a max dose of 4320. Kills everything dead and you can eat right up to the bullet hole. I won't gnash my teeth , pull out my hair or wail inconsolably about 4320's demise, I am damn sure that there are other powders that can replace it for me. Magnum Bob

I got an extra can, loading for my bud's .416 Rem. Actually traded a guy some RL-26 for some 4320. Seems they're both scarce.

IMR4320 is the only thing I've ever used for the 350 Rem Mag. Load data for that cartridge is scarce, especially with new powders. Losing IMR4320 is a tragic.
