I am planning on getting some loads put together for a Remington 7400 and would like to use a powder that creates as little residue as possible. I have 4320, H380, AA2520 to start with.

Well I started shooting for reliability. I fired 4 Remington 150 grain PSPCL's, all functioned perfectly. I then loaded the three good pieces of brass (one was a factory defect) with 45.2 grains of AA2520. Not enough gas volume to function. Then I tried 53.0 grains of H380, not good enough but almost, kind of dirty too. Then I tried 47.0 grains of AA2520, almost but not good enough. Next up is AA4350, 56.0 grains, works like a charm, last I try 55.0 grains o AA4350 and I get a reliable load a bit off top loadings. In all reloads the 165 grain Ballistic Tips were used. Aparently the 7400 was designed to work with medium slow burning powders if thats how you categorize the 4350's. Beyond that the same three cases were used for all loads and were still in good enough shape to load once more.

Vihtavuori powders are the cleanest burning on earth.
I'll agree with that.
I'll also add:
1) Cleaning is part of the game. 2) I'm more interested in accuracy than cleanliness--just look at my living room........ 3) Pressure affects how clean a powder will burn. What burns nice and clean in my 180 grain bullet's cartridge may not burn clean in your 150 grain bullet's cartridge. 4) What a good many people complain about when they are talking about "dirty" powders is carbon, which is the easiest thing to clean out of your barrel. If you're having trouble getting the carbon out, and you're not rushing the solvent, try a new cleaner.

Those last four Gentlemen are real profesionals. VihtaVuori powders are cleanist burning powders in the whole world. You need N-150 too. Of couse there are N-540, -550 and -560. But the first ones are good enough.

This is not a recommendation ,but the cleanest powder I've fired in a 30-06 or most any rifle I've used it in was Blue Dot. roger

I really cannot say which might be the cleanest burning but I sure am impressed with how clean Varget/AR2208 burns in both my 303 Brit and 303-25. So there are powders that burn cleaner than that! Wow!
