Added more data and info, still raining :lol:
Did some checking today, since it is raining and I don't want to go out and ruin my hairdo in the rain.
I got busy with my MEC 9000GN and the 20/28 Alliant powder. I tested various bushings for size and weight of powder drop. All of the MEC bushings are about .996" long, so if you have a different brand of loader you can compare bushing volumes to the MEC bushings. I dropped 10 charges from each bushing using a full small bottle of Alliant 2028 powder and a PC RED powder baffle. If you are not using the baffle, you might get different drop weights and more variation as the bottle gets empty. Since this is a progressive press, a single stage press may drop a heavier charge from the same sized bushing, depending on what procedure you are using, and how smooth you are. Remember, a slight dwell at the bottom of the lever pull, will improve the bushing fill and give more consistent drops.

I found the data for the P-W bushings and added it to this chart. Of course, these are only suggestions and all that other Legal Blah-de-Blah

Mec Bushing #11 .263 dia
#12 Not available
P-W #2A=.285
#13 .287"
#13A .293" 11.3 Grains 20/28 PW 2a or 3a
#14 .303" 12 Grains
#15 .310" 12.4 Grains P-W #B= .314
#16 .318" 13.2 Grains P-W #C = .322
#17 .327" 13.7 Grains P-W ---C1 = .329
#18 .333" 14.1 Grains P-W ---D =.332
#19 .342" 14.9 Grains P-W --- D1 = .341
#20 .349" 15.8 Grains P-W ---E= .355 -.360
#21 .357" 16.4 Grains
#22 .366" 17.2 Grains P-W ---E1=.367
#23 .374" 17.8 Grains P-W ---E2= .379


Thse were all the bushings that I had that were anywhere close to the suggested drops by Alliant at the link below.

http://www.alliantpowder.com/reloaders/ ... owderid=23
These are my results, yours might vary from this, so check your press with your powder! Hope I saved somebody a bit of trouble. Have fun, kill targets.
If you have a P-W, and have some of these bushings, please inform me on the drops and we can fill in the P-W blanks. I do not have a P-W press

Thanks Curly!
I will verify that the MEC bushing recommendations we publish were performed by MEC using a single stage machine, so the lower weights for each bushing are expected for the progressives.

Thanks for the great info. I've been waiting for 20/28 to show up locally. Are you seeing it on the shelf yet, or are you having to order it on line?

I picked some up at Recobs target shop early last fall.

I have not loaded any yet as currently my 20 gauge hulls are all full, and there will be no sporting clays or skeet available for me to shoot until the spring.

I bought 16 LB from the first batch that Gamaliel got in.

FYI - 19 bushing in MEC 9000 drops 14.8 for me.

I am putting it in a AAHS 20 gauge hull with Claybuster clone of WAA 20 and Nobel primer. I have not chron'ed them. Expect its slow. Recoil is light (compared to 15.3 Universal) fits nice and it hits hard as all get out.

Thanks, Curly! You definitely saved me some time. After arguing with local sellers for a while and getting nowhere trying to get them to get 20/28 in, I finally ordered some online. I can't wait for it to get here. I'm out of Unique!

I think that you will like it, although it is not quite as dense as Longshot or WSF. But, I do need to check my notes to insure that is correct.

I have added more data to the original posting. So you might want to look back at it.

Posting updated to include P-W bushings near to Mec sizes

Thanks Curly. I just bought a 28 ga shotgun, 2028 powder and Mec grabber. I set up the reloader last night. I will start reloading tonight at least I know what bushing to start with. My load calls for 13.0 grains. I am anxious to see if the 16 bushing throws the same as you reported. I am also using a Red Powder Baffle.

Curly GREAT info, Thanks. One question, and it might be obvious, but the numbers you list last are the internal diameter of the MEC dies, correct? Do they correspond with the Hornady bushings and their numbers that will fit in my PW 900's?

Yes those are the ID specs of the Mec bushing in 0.001", The bushings with three digit part #'s = their size in 0.001" units. You may find sizes in Hornady that do not exist in RCBS or Spolar and verse vicey. So a 311RCBS/Bair/Pacific and Hornady (maybe more, not sure about Spolar) bushing is 0.311" +/- their manufacturing tol.. All of which will fit the P-W press.

Curly, Is this the Red PC powder baffle you are all talking about that you are using ...... http://www.gamaliel.com/cart/product.ph ... 626&page=1

If so I am going to get one,I have a mec 600 jr mark V and would like to get a more consistant powder drop using my alliant unique powder.

Yup, that is the part, I suggest that you get 2 or more. I have seen them break where the bottle is attached. Do not know whether it is user caused or what. I have never broken one. Some folks question the merit of the baffle part design. I use it mostly to control powder dust and particle drool.

My Red PC Baffels lasted about a year before they cracked. Now I keep and extra one in stock at all times.

Curly, after having made Mec powder bushing conversion adapters for PW presses to use mec powder bushings in those machine, the ID of the Mec bushing is all the conversion you need to cross reference it against PW bushings of the same ID as well.

Granted that every press is going to throw a bit different due to how the machine is bolted down, and even how someone is reloading for any bushing, both the Mec and PW style bushing are about the same length *, so it will be the same ID of both bushings that will put you in the same hunt.

* PW/RCBS/Hornaday bushing average around .998 long, while the Mec bushings average around .996 long. But should note, by the time you lap a PW bushing so it fits the bushing carrier correctly without protruding above the top of it when seated, you end up with with the bushing being in the .996 length anyways.

I know that, you know that but the issue is this. Most folks don't know the ID of the Mec bushings nor the P-W bushings. If I give them an idea what size Mec bushing does a job, sure as heck they are going to ask me which bushing to use in a PW or some other press. I just tried to get all the different bushing systems on the same page using numbers that the average shmoe can cross reference to. You may not be aware that unlike you and me, not all folks with presses have the means to measure their bushing bores. :D

Hi Curley,
This is my first post so be kind.
I want to load the old WW28 hulls with the old WA28 wads and Alliant 20/28 powder. I can't find any reloading data for this combination. My guess is 13 grains and use a MEC16 bushing. I have a Spolar and have a adapter to use MEC bushings.
Thanks for the help. :?:
Dick
