I am really glad Hodgdon made Universal and that Alliant made Unique a whole lot cleaner.
Any experience with Alliant 20/28?
Has anybody reading this thread tried 20/28 in the 16?
Over a few decades, I've burned up only 2-3 lbs of Unique; a limited number of 20 & 28ga loads and a variety of handgun loads. I can't fault its versatility but it was never a first pick for me in anything I loaded. When Universal Clays became available I abandoned Unique for shotshells in a heartbeat.
For handguns, I hung onto Unique for awhile in spite of it's dirtiness and poor metering; UniClays didn't seem to deliver the same accuracy for me.
Then along came 20/28. I'm biased in favor of Alliant over Hodgdon and the switch to 20/28 in the 20ga was a no-brainer for me. Generally speaking, compared to Unique, it's squeaky clean, meters like water and is about 0.5 grain more economical in handguns. Even so, That wouldn't be enough to wean me from Unique if it weren't for the fact that I've found it to give better accuracy in a number of recipes. I don't think there's a single published handgun load for it, but many experienced handloaders have tested it and are in close agreement in how favorably it stacks up to Unique.
I now have 10 lbs of 20/28 and zero Unique so I'll eventually get around to trying it in the 16. In the meantime, I'm wondering if anyone has.

I converted to Universal and never bothered with 20/28....not for any particular reason other than I had already developed the loads I wanted with Universal.
The only loads that I know about using Remington hulls and 20/28 are on Old Hunter's spreadsheets. They were done by a fellow Sorrentino, 15.5 grains of 20/28, using Win, Ched and Rem primers, DR16 and 7/8 oz of lead. pressures are 5700 to 6200 and the velocities are 1100 to 1125.
I have about one year worth of experience with the 'new' Unique and 7/8 oz. loads. I like it and it didn't soot up my 1100 like the 'old' Unique.
Kind of a nice load really.
20.0 grains Unique
7/8 oz. of lead shot.
This is a takeoff of a Unique 1 oz. load. I have no idea of the velocity but it kills pen raised pheasants just fine. I also used it for Sporting Clays. It does cycle the 1100 without a glitch.

I loaded Unique for many years beginning with 20ga and handgun loads for 38, 45, 10mm and 44spec. before I used it in my 16ga. It always worked great in my handgun loads and metered well in my powder measure. I found it to be clean burning in the handgun but the 16ga loads did get a little dirty.
I have since switched to Ramshot Silhouette powder for my handgun loads and have been experimenting with Vectan powders in my 16 and 20ga loads with good success.

Unique and 20/28 are very close in burning rate and can be substituted for each other by weight. However, 20/28 is more dense, so a given powder bushing will drop a greater weight of 20/28 than Unique. I have used both at the same weight in the 16. The only difference is the space between the shot and the hull mouth if the same wad and shot charges are used. 20/28 was developed to be used in the new Winchester 28-gauge HS hull when stack height proved to be a problem with traditional charges of Unique.
Lyman 5th - Federal 209A 19.5 Grns of Green Dot, Rem SP16 wad,1 oz. of shot. 1257 FPS, 10,700 PSI. I don't like Remington wads in Federal hulls because of powder migration. Someone with a lot of knowledge that I trust suggested dropping back 1 or 2 grains of powder and using a nitro card over the shot. I went to 18 grns and everything is good IMHO.

I’ve loaded some 7/8 and 1 oz 20/28 loads in Cheddites and Federals. Have to look in my reloading log to see how much powder, what they chronographed at and how it burned. I did settle on a 1 oz GD load, but I have a fair bit of GD to burn up. I can dig it out if anyone’s really interested.
