I remember getting 1000 Sako 156RNSP .264 for $9/100 from Higginson back in the day perhaps Ammomart? Still have a bunch.That is a very good price in today's market. A number of years ago,
I bought 50 lbs of Norma MRP for $8.00/lb Still working on that lot.

I envy you. Norma MRP is such a great powder. Use it in several rounds I load.
Yes, I also find it to be a great propellant. I use it in 6mm Rem, 257 Weatherby, 6.5x55,
6.5x55AI, 7x57, 270 Win, 7mm Rem Mag, 30-06, 308 Norma Mag & 338 Win Mag. Dave

7828 works well in my 270 WSM super accurate I love it, you got a great deal.
I put that #### on everything
From 6.5x55, 7x57, 7 MM Rem, 30-06, 300 Win and 300 Bee.
Got a couple more rifles in 6.5x55 that i haven't fired yet, and i'm planning on using this powder hope it will work just fine.
Got a new barrel for my M03 in 300 win mag that i haven't shot yet and my latest one is a 300 WSM that hasn't been fired yet too, i think i got to go back and buy some more .

Wow, what a deal!
I love 7828, best powder in several cartridges I load.

So where can one buy this elixir of powder? Publicly available or was this a private sale?
I use it in my 7mmMag and most recently in my 6.5X55, nice powder. I think it would work in several of my other calibers too.
Cheers
I really like IMR7828 as well as IMR7828SSC. I suggest it to certain friends that are familiar enough with powder burn rates and what kinds of trouble they can get into.
I am always surprised by how many people have inherited reloading equipment, 25 year old cans of powder, bullets, primers and for some reason the reloading manuals weren't included in the mix. I often get a blank stare when I suggest a hard copy manual for safe recipes and instructions. Many declare they can get that for FREE online. Yup you can, but having a hard copy handy, with all of the info there in front of you, when you need it, instead of having to log in an look for it, is just so handy.
One of the most valuable bits of information in most current loading manuals it the "powder burn rate chart," which actually scares some people off, mostly because they don't understand what it's for.
The burn rate chart gives you an idea of what the powder is useful for, concerning the length of the pressure curve. Take heed, that is a very simple explanation and there is much more there than that. The burn rate chart will list powders with similar burn rates that should work very similarly to a favorite that may no longer be available or you've run out of, etc. THAT DOESN'T MEAN LOADING DENSITY IS THE SAME OR THAT YOUR PARTICULAR LOAD FOR A DIFFERENT POWDER WILL BE SAFE.
The chart is simply a good place to look for an alternative powder that will deliver similar results.
IMR7828 in both of its forms is incredibly consistent between lots. It's also slower than H4831 in both forms and as such, in cartridges like the 6mm Rem, 6.5x55, 6.5x57, 7x57 and the venerable 30-06 spfld it can be a good choice for a single go to powder for all of them. It's also very useful in some magnum cartridges for most consistent, excellent performance. I also use it for loading 7-08 for my grandson and 308 win for his step mom. I can fill the cases to the shoulders of each cartridge, load lighter bullets in the 130 grain range, keeping recoil manageable for both of them while maintaining acceptable velocities for hunting purposes.
IMR7828 is similar in burn rate to Reloader 25, 26, H1000, Magnum Ramshot and N165 to name a few. All will work in similar applications. Of course some will be better than others but so much depends on other things, such as barrel length, rigidity, quality of components as far as consistency goes etc.
Many folks consider IMR 7828 to slow to be useful. However, it's one of the powders that has an extended pressure curve but at a lower spike pressure and as such it really performs well in standard length medium bore cases. Example, I listed 30-06 spfld as a case it's useful in. It is, but only, IMHO, with heavy bullets of 180 grain plus.
I went into a bit more than most want to read. Fine. I'm trying to point out that even though IMR7828 is a perfect choice for many situations. There are other powders that may work better.
Here's another suggestion that makes many cringe in horror and present crucifixes for protection from blasphemy.
IT'S OK TO MIX DIFFERENT LOTS OF THE SAME POWDER, FROM THE SAME MANUFACTURER, WITH THE SAME DESIGNATED BURN RATE AS DESCRIBED BY NUMBER OR NAME ON THE CONTAINER.
To make a long story short, I always mix different lots of the same powder into as large a lot as possible. The reason for this is to maintain an extremely consistent burn rate, so I don't have to figure out what's gone wrong, when a container runs out and I have to open a new one.
I always purchase primers in at least 5000k boxes for the same reason and bullet lots in bulk if possible. I shoot to many firearms to be constantly developing loads.
Also, keep a diary of your loads. I have three diaries, one is 55 years old from its start. It lists loads for individual firearms, many of which are now obsolete and information is no longer available for. I still have some of the very cheap, even for the time powder that is no longer made and there just aren't any loading tables for online. This is where burn rate charts from days long gone come in very handy. Especially for surplus powders from WWII, Korea and Viet Nam, not to mention those from offshore, such as Bofors and a few others. I had some really good powder that only had Cyrillic markings on it and a 1943 manufacture date. It was very close to but slightly slower than the old 3031 designated powder. Only was able to get one 20kg container back in the early sixties. It came in a brown wooden box, with a heavy tarpaper liner, which was sealed with tar all around. I seem to remember $10 for the container because it was a one off and heaven forbid, RUSSIAN. A lot of my buds at the time were pretty smiley with how well it performed.
Surplus powders, are still available the very odd time. Often they're one off batches, made up for commercial orders from commercial loaders, such as Hornady, Federal etc. They're usually less than half the price of comparable powders but will require some experimentation to develop good loads. Again, this is where burn rates really shine.
For instance, I have two full canisters of IMR7828SSC, with appx 10 pounds each, filled right to the top. There is also a half full container of the same powder. All of it is a mix of close to a dozen different lots, which I have accumulated over the past 10 years for an average price around $15 per pound, from estate sales, local gunshops dumping for tax purposes or from unopened cans at gun shows. Unless I'm doing someone a favor, I don't purchase partial cans of propellant and I know/trust the seller well.

I bought the last 5 8lbs jugs for $180.00 each but there's 1 lbs bottles available.
IMR 7828 $26.00
IMR SSC 7828 $25.00.
Not sure if i'm getting in trouble with the mods if i mention this supplier name as they are not a site sponsored.
