I reload 380, 9mm, 40S&W, 38spc, 357mag, 45acp, 45colt, 454casull, 44mag, 223, 22-250, 243, 270, 30carbine, 30-30, 308, 30-06, 375, 300win mag, and 45-70. I think that's it for now. I am concerned with having so many different powders stored at home and room for them. Is there anyone with opinion on maybe sizing down to 3 for pistols and maybe 3 for rifles? It might be hard as I'm an old dog and do have some favorites that I hate to give up (ie H335 for 223, 2400 for 44mag, Unigue for 357.) I am open for suggestions. Would possibly the new IMR Enduron powders replace all of my needs properly?

Not sure about the new IMR offerings.
For your pistols, maybe Unique, Power Pistol and AA#9
For your rifles, RL 15 or Varget, IMR or H 4350 and 'something' for the 45-70 that will work for some of the others also.
Lots of options out there----IF you can find them.

Look in your reloading manuals and your answer will appear to you.
Lots of options.
You could use Black powder; then you will only need one. Works for everything.

Yep, a single powder would work in all of them, but obviously wouldn't give you optimal performance.

Here's what I'd suggest.

Unique for your .380, 9mm, .40, .38 spcl, 357, .45 ACP. .45 Colt; plus for mid-power loads in the .454 and .44 mag. Unique will be a few fps short of maximum power in your .357, but why would you want maximum power from an undersized "magnum" when you have three more powerful revolvers?

AA1680 for full power in the .454 and .44, plus .30 carbine, and some loads in the .45-70. You could also use IMR 4227 or a couple of other powders in this burning range, but I've found AA1680 to be very consistent.

H4895 or IMR 4895 will be great in .223, .22-250, light bullets in .243, .30-30, .308, and light bullets in the .30-06. It is also a good choice for both standard (black powder pressures) and +P loads in the .45-70. There are several other powders of this approximate speed which would do nearly as well, but 4895 has been proven at higher and lower pressures and is even adaptable to reduced loads.

Any of the 4350's will do well with heavier bullets in the .243, and .30-06, It is a favorite in the .375 H&H, and quite passable in the .270.

The .300 Win Mag is the outlier, requiring something like IMR 7828 (preferably the SSC version) if you shoot bullets from 180 grains up in it. The 4350's will actually "get you by", but are best with only 150 grainers in this caliber. So, go ahead and stock some 7828 as you can also boost your .270 velocities by 50-75 fps over 4350 with it. 7828 ain't bad with 100 grain bullets in the .243, either.

Others can make recommendations which would accomplish much the same thing with different powders. The ones I've recommended are those I've used extensively and am confident in, which doesn't mean that an entirely different set of powders wouldn't do as well.

Thank you very much Stonecreek for all the info, it is very well taken. I will try those. I don't seem to care for 4895 though, even though I use it, cause it doesn't meter well. Almost have to hand trickle every load.

There are a lot of powders that overlap. For Pistol you can get down to 2. One for non magnum, and one just for true magnum loads. Rifle is a little harder. Varget will work in a lot of cases but not every bullet weight for those cases. At least not great. I wouldn't worry about too much powder unless you have 50 or 60 pounds. Even then proper storage and separation can go a long way.

I've reloaded for all except 3 of the cartridges you mention. The only ones I use the same powder for are Longshot for 9mm Luger and 40 S&W and RL-15 for 223 Rem. and 375 H&H Magnum.

You could get by with much fewer powders but will find you won't get optimum performance by doing so.

A couple of powders you might consider for use in multiple cartridges would be Titegroup for handgun ammo and IMR 4064 for rifle ammunition.

Stonecreek.....sent you a PM.
