Single powder for a bunch of different cartridges

[Imageview]

So I’ve been cleaning up my reloading tools and decided to make a portable reloading kit using a Stanley lunchbox and a selection of Lyman 310 tools and dies (for some reason I find them very pleasant to use). I have a scale, funnel, several 310 tools, and dies for the following cartridges:

22 hornet
38/357
30-06
45-70

Basically everything I need to reload those rounds aside from powder, projectiles, brass,and primers. At some point I’d want to add calipers, but there’s plenty of room for those as well as the bullets, brass, and primers. In the lid of the lunchbox there is a wire bracket for holding a thermos, and it occurred to me that a bottle of powder could fit in nicely.

So the question becomes which powder? My gut says 2400, which is fine for reduced loads for 30-06 and 45-70 and full power hornet and 357. But I’d love to hear if anyone can come up with another option with published data. Obviously with such an odd and diverse selection of cartridges not much would make sense and nothing would be optimal across the entire range (probably doable with 2 powders, definitely with 3), but kinda a fun question I’ve been pondering and I’m hoping to get more input.

Thanks!

2400 would be my pick too but it would be so much better to have a few different powders.
3031 would work for 30-06, 45-70 and poorly for 22 hornet but not for 38/357 at all.
How about 2400 for 357 and 22Hornet and 3031 for 30-06 and 45-70?

3031 or something like 4895 would be my choice definitely for #2, and adding a third powder would be along the lines of bullseye or unique. Realistically those combinations cover pretty much anything I personally have any interest in shooting in rifle or handgun assuming I can find a decent load for a particular firearm. Still if I had to pick one single powder for this portable reloading kit, i'm having a hard time beating 2400.

If you have a bunch of 2400, use that. If not, I've found TCM to be a good substitute for it.

I use 700x for most all pistol calibers (and 12/20 gauge), and H4895 for most of the rifles I shoot. 4198 is also a very versatile powder.

I have not yet tried 700x, mostly because I happened into 5lbs of tightgroup and that's pretty much a lifetime supply for me (not much of a pistol shooter, I've shot more 38/357 out of rifles than I ever will in any cartridges from pistols combined). I've had a bottle of bullseye waiting for years, but haven't gotten to it yet either. 700x does seem versatile on paper however, so if I happen across some maybe I'll pick some up.

Go here: https://hodgdonreloading.com/rldc/ and select "Filter by Powder" It will list every cartridge that Hodgon has data for. Try different powders to see what fits you best. You will have to select either by "Rifle" or "Pistol" to see what overlaps.

Edit:

I don't have a single powder for all the reloading that I do for one cartridge. In my 243's I shoot 58 grain, 70 grain, 95 grain and 105 grain bullets and I use a different powder for each of those bullet weights. In the case of the 95 grain bullet weights, I shoot Berger VLDs and Hornay A -Max bullets and they each use a different powder.

You can try to use one powder but you'll never be happy with the results in all your guns.

I used 700x for 12ga when I was loading trap loads. Never tried it in a handgun load. Seems a little fast for most of the pistol calibers I loaded. 4895 and 4198 are good powders for many rifle cartridges.
