IMR 4064 and IMR 4198(what carts like these?)

What cartridges seem to like these the best? I know IMR 4064 works will in large cases but I'm not quite sure about the IMR 4198.

Anyone have experience with either of these?

IMR 4198 was one of the favorite powders for the original .222 Rem. A little fast for .223 but can be used with lighter bullets. Good for light bullets and light loads in many calibers, including smokeless loads in BP cartridges.

IMR 4064 is good in so many things from .220 Swift to .308 and beyond.

Why, did somebody give you those powders? Have you got a loading manual?

Oh I've got plenty of manuals......and I bought the powders.

IMR 4064
The IMR 4064 for my .375 H&H mainly (the manual recommended that powder for it...I've been trying IMR 4350 for it but the best I can doo is 1.5-2.5 inch groups or so with that....if it doesn't seem to like IMR 4064 I'm going to try IMR 4831).

IMR 4198
I was told that IMR 4198 works really well in .45-70 (even though my jacketed bullets seem to like IMR 30301-I was given the tip that the heavy lead loads like IMR 4198) I believe it is a faster burning powder than IMR 4895 which is supposed to be one of the best powders for .308 but I was also told that it tends to do well with the heavier .308 bullets. However......I have my reservations about that...I guess the theory there is that if the bullet intrudes deep into the case and you have a faster burning powder you don't need as much of it????? Maybe something like that? I'm not sure on the .308 I'll def want to see some manual loads with that before I even think of trying it with the .308. But I know that like you said Jim, it is supposed to do well in the .45-70 with the heavier lead loads.....

So mainly the IMR 4064 was purchased for the .375 H&H and the IMR 4198 for the .45-70 with the heavy lead bullets 405+grs.

If someone had given me the powders..unless they were sealed in the canister brand new...I'd give them right back....I'm a reloading manual freak I love just reading what the diff books have to so say etc. I'd really like a copy of A Squares any shot you want book??? If anyone has one of those lying around I'd be interested in a review of it.

Thoughts??

Thanks
Pat

I've used IMR 4064 (DuPont prior to that) for about 40 years in a 22-250. It yields very good, intermediate velocity, loads for all weight bullets.

I think you are right in the ballpark.

I would never attempt to load .308 with heavy bullets over 4198. The 4064 ought to do well there; I use Varget which is kind of the Australian imitation of 4064.

My best loads for the 375 used IMR 4831, but IMR 4350 works well, too.

loads

Scorch
Yea they ordered H 4831 instead of IMR 4831 So I went with the IMR 4064.
Mine seems to do pretty good with IMR 4350 (.375 H&H)
I'll keep trying to get some IMR 4831.
I wish the bloody bullets for the .375 H&H weren't so expensive!!!!!!!!! I don't suppose you know of a good bullet for a reasonable price? Speer Hot Core
235gr???

Jim
I think I'll avoid the .308 loads with the IMR 4198 then and focus on using it for my .45-70-It really is a pretty fast burning creature isn't it?
I use Varget a lot in .308 and in 6.5x55 swede(the swede loves it every single load I try...of course within reason...seems to do an inch or less with Varget)
Just out of curiosity what do you mean by an Australian imitation of IMR 4064?
(manufactured there or what?)

Thanks for the info guys!

Hodgdon does not manufacture powder, except for Pyrodex and 777 fake black powders.
Their "Spherical" powders are made by St Marks Powder in Florida on the same production lines as Winchester Ball powders.
Their "Extreme" powders (Varget and all the numbered powders that sound a lot like IMR designations such as H4831) are made by Australian Defense Industries. As are their flake shotgun-pistol powders like the Clays series.

4064 is my goto for cartridges like the 6.5 Japanese, the .243, and the .300 Savage.

I have used 4064 with 150 grain bullets in a 30/06 for years.I use something a little slower with heavier bullets.

I have had great results from the 4064 in 30-06, .300WM, 22-250 7mm and a few others. Getting rady to try 4064 in 6.5X55 Swede as I heard it did good in that caliper from a friend.
Haven't tried the other powder yet.

In my experience

4064 is the best I have found for my .308's and 7.5 Swiss. It works okay even in .223's. My 30-06's with 150-155's like it as well. 4198 works great in my 223's and 6.8SPC's.

I use IMR 4198 in the .222 for some loads. I've heard that some shooters use it in the 45/70 but I don't have any experience with that caliber. IMR 4064 and the AA version are just the ticket for my old 742. It shines with a 180 gr. bullet, and gives me right around 2700 fps. I use different powders for lighter bullets, but you will have a hard time finding a caliber that 4064 doesn't work well in over the.222,.223 calibers. BTW I use 4320 sometimes in the .222 and it does quite well with 55 gr. bullets. A friend has a 45/70 and he usually uses IMR 3031 or RL7. Hope this helps. Enjoy. CB.

Generally, the faster powders like 4198 work best with lighter bullets. It's one of my favorites in .223 with bullets like 55gr and less. I've never tried it in heavier calibers, but I'd be real careful if you are using a gas-operated gun in something like .30 cal. They can (will) be damaged if you use powders with burning rates outside the recommended range.

4064 was at one time one of the most popular powders for competitive shooters in .30 cal guns, but because of its long heavy sticks it was hard to feed through powder measures with consistent results. Then about 15 years ago or so, they put out some bad batches of it and velocities were all over the place. Since newer, easier to use powders were becoming available, 4064 got kind of left behind by the long range shooters after that. It works great in my M14 guns, but it's still hard to measure.
