Rifle powder A or B

Those are good powders should have data for all of those cartridges. You might look at h1000 and ramshot hunter as well.

Retumbo, H4350, and Varget would be the 3 powders I would use for the mags, 243 and 30-06, and 7-08, respectively.

If you could only have 2, with those calibers, your H4350, or IMR 4350 would be my first choice. For the 2 magnums, I would want something slower like 4381, either H or IMR. But I prefer RL22 for my mags. It has always performed better than the 4381s when compared them against each other in 7mm and .338.

But there are a lot of great powders available. I put a couple of lbs of Win 760 in my cart yesterday at Midsouth. Today I went back online and it was still on my cart, available. I found one other rifle powder, and 3 shotgun/pistol powders I wanted and pulled the trigger. The 5 lbs of Clays did disappear before I checked out but I was able to spread the hazmat and shipping fees over 10 lbs of powder.

PS: I’ve never loaded for the 300 WM.

There is quite a void between '1-2,' and '48.' Just saying.

Actually, you should do quite well with the 4350/4831 combo, with the caveat that it may not be optimal in the Magnums... but would certainly work.

Well I think that you will find that even the big guys like Winchester and Remington (who would benifit greatly in regards to inventory) do not use just two propellants for that wide a range of calibers. The two that you mention certainly will produce usable ammo but the velocity and other paramiters will always be a compromise in all but one load most likely. We often have can I get by on just one propellant threads it seems.
When I work up a load (having the luxury of years worth of buying one pounders of various propellants to try) I will find a first and secomd choice that plays well with that particular firearm and save that data for future use. Look for velocity, pressure, temp stability, and on target real world results. Some loads are easy to find and some I am still searching for after years of trying.
You seem to be asking the following question:
I purchased two large lots of tires on rims for my fleet. Can I modify them to fit all my different brand and model vehicles and race with them at the 1/4 mile track? One can argue making adapters and opening up wheel wells etc. but really!!!?? Better off doing it best choice in the first place IMHO.

The two you mentioned would do nicely. In our day and age, inspite of more verieties then ever, we have fewer choices. Look@ as much data as you can find & make a list of the 3 top velocity performers. They are usually the best thing to use.

I would say try to stick with single base if you can.
N555 or IMR4350
I haven't tried IMR4831.
Maaybe both. N555 and 4350 would work in 7rem.mag. and 300win mag but you might want something a bit slower.

The n300 series is single base and the n500 series adds nitro....
Your asking for the best compromise powders and that is strictly opinion...
If it were me and I could get anything h1000 and h4350 would be my first picks. Varget is a good possible sub for the 4350 if your rifles like it better. Running simular bullets and primers will reduce the variables but there are still a ton.

The N500 series of Vihtavuori propellants provide the utmost in performance. Vihtavuori N500 high energy powders are the perfect reloading option for a rifle shooter who is looking for added velocity and range with heavy bullets. Nitroglycerine has been added to the traditional single base rifle powder to get better energy content. The N500 Vihtavuori series offers seven different smokeless reloading powders with different burning rates, suitable for a variety of shooting disciplines such as long range target shooting and ELR

Agreed. A shooter and reloader doesn’t need a whole shelf of different powders to do everything they could ever want to do with firearms. I could do everything I need (and largely DO) with just 5 powders.

I shoot quite a few different cartridges which I could do without which drive me to carry a few extra powders, but if I were the type of person to try to limit my diversification with interest in inventory management/minimization, then I could do everything I want to do with Unique, H110/W296, Varget, H4350, and Retumbo. Pistols, puff loads in revolvers, magnum revolver loads, varmint through the largest of game cartridges, short range blasting through long range precision. Maybe these days I’ll need to add a super-magnum powder as I start more into ELR, but that’s such a super specialty, it doesn’t really fit this exercise.

4350 works fine in all of those except maybe 30-30 and .243. 30-31 works fine in those and everything else you mentioned except 300wm.
If had to choose only 2 powders it would be 4350 and 3031

I thought you would have picked 4064 over 30-31 interesting.

I love 4064, but it's kind of in the middle. If he hadn't thrown a 30-30 in the mix I would have said 4064, but 30-31 will service the 30-30 better and the 243 almost as well.

I actually like H1000 better in the 300wm than 4350, but not in any of the others he mentioned.
H1000 and 4064 would be good choices if you took the 30-30 out of the mix.

Well they had me fooled it loads loads and shoots so much like IMR4350 it appeared to be single base. Compared to W760, which is much more temperature sensitive, denser and burns way dieter than a 4350 powder and N555.
Does anyone have any idea how much NG is in N555?

N500 powders SDS gives the percent nitroglycerine at <15%.

That makes sense, typically ballpowder has up to 40%.

It really depends on the bullets you will shoot out of those calibers. I would personally choose
3 powders: 4831, 4350 and 4064. That would cover your bases pretty well. As a matter of fact, I have been able to find each of these powders so far this year and bought a pound of each which should keep me going hopefully until nightmare ends.
