Looking on the Hodgdon site they have IMR POWDER AND THE SAME ID NUMBER WITH A Hodgdon BRAND H.
Do they make both powders if so what is the reloading difference with the same number?

Since everyone is sold Out of powder for sale.

Has anyone tried the H Superformance powder?

It is listed as a reload power for those that want to reloaded the same powder as Hodgdon makes for Hornaday ammo.

I have not reloaded much since I found the cheap Hornaday Whitetail ammo. Cheap and shoots from one hole to less than an inch group in 6 different rifles from 270,7 mag and 7mm-08 with the 139gr sp and 140gr for the 270s.

Downside flat base and so so BC but to 350 great and 7mm-08 gets 2880 and the 7 mag gets 3100+.

Is this the powder that Hornaday uses to load their rounds since I need to load some more rounds for a trip back to take pxs and hog hunt with some old bullets that I have.
Thanks. Jim

Hodgdon doesn't make any powders. It markets them.

The "Hodgdon" line of powders is mostly made by ADI of Australia (ADI now has another name, but I can't remember it.) These are powders like H4227, H4198, H4895, H4350, and H4831.

"Hodgdon" branded ball powders like H335 and BL-C2 are made in the St. Marks, Florida facility which was once owned by Olin (don't know who owns it now).

The "IMR" line of powders are now mostly made in Canada. The same numbers like IMR/H4350 or IMR/H4831 are similar in burning rate but have slightly different burning characteristics. Therefore, the powders are not interchangeable, often requiring different charges and may or may not achieve similar results.

Don't confuse a marketing company or name with a manufacturing plant.

Ammunition manufacturers don't used canister grade powders for their ammunition, so don't assume that you can duplicate a factory load even if you think you have all of the same components. Every manufacturing lot of a given powder will tend to vary by some degree from one another. So, only those lots which fall within a specified range are packaged and sold as powder to individual reloaders. The lots which vary outside of the standards for canister powders are sold in bulk to ammunition manufacturers who will test them (and sometimes blend them) in order to tailor them to the specs for a given caliber and bullet weight of their particular ammunition. Thus, the powder in the factory loads is almost certain to be different from the powder you can buy off the shelf in some unpredictable way. Assuming that it is a particular powder and reloading with the same volume (or weight) of that powder in a canister grade will not necessarily result in factory ballistics and can be dangerous if you are misinformed of what powder it is to begin with or if the canister powder is significantly faster burning than the bulk powder lot or blend.

Has anybody tried the H superformance powder?

All I have is old H4831 that shoots well except 140gr bullets in 7mm-08 and it is a lot slower than the 2880 FPS 139 gr Hornaday whitetail loads

Now is not the time to look for powder to reload.

Thanks for the info.

Happy Thanksgiving. Stay safe.

All I use in 7mm is H4831. Fast twist rates like 1/8 seem to like heavier bullets up to 175. Standard ones of 9 like 154 grainers. Twists slower than that like 9.5/1 to 10/1 do suggest the use of a faster powder like 4350's. Different manufacturers, similar burn rate.
Hope this helps.

All that comes to mind as interchanable is IMR-4895 and H4895...WW760 and H414..Im sure there are some others, but its always best to go with what the Reloading books state..and even the above listed sometimes show a grain or two difference, for whatever reason..probably the test gun itself showing a difference as guns are an inity unto themselves..

Burn rates are slightly different between the H and the IMR powders that end in the same number.

A little bit of caution is in order if you're looking for top performance.

Some of the Hodgdon powders still come from Nobel in England and France, Bofors in Sweden, and maybe Lovex in Czech(?) They just buy whatever, wherever and repackage and distribute. And apparently they are having issues with Int'l shipping regs at present as well, as to quantities that can be shipped in certain fashions and they are trying to find ways around that, which apparently will also jack the price.

Not strictly true, they do manufacture Triple Seven, Pyrodex and Goex black.

IMR 4885 and H4895 are not interchangeable, as can be seen in Hodgdon’s .30-06 data etc. The IMR version has a higher maximum charge weight. However, W760 and H414 are identical with only the normal lot-to-lot variations.

As zeke said, a little caution is always a good idea, Id start low and work up with any of them.

there is a scale in one of my old reloading books that matches all the powders that have the same burning rates and load density. most vary a grain or two, so again start low and work up.
