H4227 And Powder Residue

[P.W.Herman]

I have shot IMR 4227 for years. I find if I don't look down the barrel the residue doesn't bother me.

I have had that happen with Unique as well.
For most mid-range magnum and full special loads I now use Universal instead as it burns cleaner.
Universal acts a little faster in my experience than Unique in revolver cartridges so backing off a couple of grains to start is always a good idea (as usual).

According to
Improved Military Rifle - Wikipedia
IMR-4227 was originally intended for rounds like .22 Hornet, 25-20, and 32-20 as you said.

I switched from Unique to Universal 15 or 20 years ago. Seems both leave debris behind with reduced charges, but Unique would leave both me and the firearms freckle faced regardless of charge. The newer Unique is a bit cleaner than the original, and I still load some SAA .45 Colt loads using it, but my .45 ACP's, .38 Special, etc use Universal.

When available I still stock both, but my "go to" is Universal due to similar load densities, accuracy, availability, and much lower chance of leaving the range with freckled face, hands and firearms.

I accept these powders characteristics. I find the positives listed above outweigh the negatives.

I will likely simply put the 4227 in the same category.

(I have a love affair with the Lee Auto Disc measures and powder through expansion system. I own at 6 or 8 of these measures that I leave setup on my most commonly used dies. The Double Disc kits have been replaced with the Auto Drum for calibers in the .454 Casull range. I've had questionable results with the adjustable charge bar, so I no longer use them.)

Me too. I have 3 and use them on my Dillon 550b. Use the traditional Dillon measure for larger volumes on rifles and such. I have had great luck with the adjustable one, however, I use the disk anytime they work for my load for convenience.

I still have a few pounds of IMR-4227 I was given, early 80's or so vintage. It checks good, loads fine. I'm trying to use it up as able.

Recently some light 45-70 loads, 7.62x39, 30 Carbine, 22 Hornet & maybe a few others. I have some fresh Enforcer, Win-296, & 2400, which is for later.
