    i am loading on a 366 20 ga loader. with the deep powder base in a rem. sts hull, what powder and wad do you use with a 7/8 OZ load ? my crimp falls in a little too much. i am using win wsf powder with rp wad . i know this is a low volume powder. i have some unique but have not loaded it yet. trying for 1200 fps.

    Unique is probably one of the most if not the most high volume powders you can use. That is what you need to get level crimps. I use universal myself, and the crimps can be a touch deep, but nothing horrible, and I'm too in love with the load to change. The STS hull is high volume, the RXP20 is low volume, so you need a bulky powder and a full charge of shot...

    In the Alliant book is a load that I use a lot in the 20ga. STS and AA hull.
    The book says it goes 1200 FPS but I have not chronographed it.

    15gr. Unique/Rem.RXP power piston 7/8 oz. wad/ Win.,Rem. or Cheddite primer.
    The AA wad loads here also but has higher pressure and does not load as well.

    This is a easy loading and shooting load that breaks clays well with 8 or
    8 1/2 shot.

    Try alliant 20/28 powder 15.5 for 1200 fps and 16.5 for 1250 to me awsome on 16 yard trap 7/8 oz 8 1/2 shot and use a claybuster clone for win. but only use on very ligth wind days and not to good in the cold

    20/28 is not a good choice in STS hulls unless you load them on the hot side. Way too many off sounding shells if loaded to 1200 fps.

    Very Interesting as I have heard that 20/28 is a very good powder for the 28 ga., but there are way better powders for the 20 ga. loads. Break-em all. Jeff

    I even had trouble with 20/28 in the 28ga (win aahs hulls, aahs wad). Lots (20-30%) off sounding shells. Switched back to Universal, problems went away. It's either a very "cool" powder, or is just hard to ignite...

    Surprised you have had problems with 20/28 in 28 ga with the components you described, skeet man. My experience is the opposite and wonder what reloader you are using?

    Universal with remington wad, very soft shooting. I prefer STS's with the remington wad and Universal. Universal is also a very good power for the 28 gauge.

    MEC 9000. My friend had the same problem with the 20s and he loads on a grabber. maybe the powder isn't cold weather friendly. I've loaded probably 100k shells in my life, and can count the bad ones on both hands, so I can confidently say it wasn't my press...

    Interesting...

    I have not had problems with 20/28 in 20 gauge loads in Rem hull yet in Wisconsin in winter or summer... I am using orange duster or windjammer wads and winchester primers.

    Be sure you are dropping the correct grains of powder. With your load, I believe it calls for 17.5 grains of WSF, using the Rem. wad, with Win. primer.

    17 grains of IMR SR7625 with a RXP-20 Remington wad and 7/8 ounce of shot fits the STS hull very nicely.
