Shot shell reloading/hulls

toad67
I have been reloading shotshells for many years in my 12 gauge. I have recently purchased a couple of 28 gauge skeet guns and love 'em. I purchased a flat of AA 28 HS hulls. I would like to get some more hulls so that I don't have to pay such a high price for loaded shells but all I ever find on auctions are the old style. All of the load data says to keep the hulls separate. Does anyone interchange them and if so how do thet work? Thanks.

    The HS hull has a different internal molded form than the standard AA. The inside of the walls are straight down to just above the base then abruptly there's a slight shoulder where the base begins its form into a cupped shape. This differs from the standard AA that is a straight taper with gradually thickening walls towards the base. As a result, the internal volume of the HS hull is greater. That all important part of the reloaded shotshell, which is the crimp, is determined by the space remaining above the components within. Using the same load tailored for one hull will not fit well within the other either resulting in a deeply dished crimp or one that will not close. Either a different powder with a different specific volume and/or a different wad is necessary to tailor that all important crimp space. Therefore; they don't mix too well.

    Given the current market for hulls I'm not sure that buying a flat of loaded hulls is any more expensive in the long run. Hulls seem to be going for 20-25 cents each. Loaded rounds can be had for 40 cents each. Components are probably gonna cost you the 20 cents difference.If you can get 4-5 loadings per hull you are still coming out ahead.

    I have been using old style hulls with HS wads without a problem. However, based on 336's comments I will have to measure the depth on the wad cup, every other measurement is the same as the old wad and they pattern fine.

    Just starting to shoot the HS and keeping the hulls separate, so I will follow this thread a bit to see what we can all learn.

    Best of luck

    Thanks for the input so far guys. 336 Marlin identifies the problem very well and is the same thing that I have heard is happening. I did not want to make the same mistakes myself and ruin my huls. I'm with you geeguy and want to see where this goes. Thanks again.

    the cup is deeper not much but enough it will effect the final crimp

    a piece of puffed rice or a Cheerio will fill up the space and provide the necessary backing for the crimp to close properly and will not effect the shot string when fired
