Getting correct shot weight

[star1pup]

I' m reloading 28 gauge on a MEC Supersizer. My 3/4 oz. bar throws an 11/16 oz. charge consistantly and it does not fill the Cheddite hulls enough for a good crimp. I put in one of the adjustable bars and it seems to be very inconsistant in the amount of shot thrown.

The load I' m using is 20 gr. Blue Dot and when I shot over my Chrony I got a spread of 1225 to 1301 fps. My average was 1260 and the load calls for 1265. I worry that the 1301 is just too hot. I' m shooting a Red Label 28 gauge.

You might try a different recipe with a different wad and see if that helps . I have hit a few loads that weren' t as tight as I like them and just changed recipes .As far as the spread on the chrono that seems to be quite a bit but not enough to have to worry about . Have you checked the powder charges to make sure it throws consistant each time.

ABSOLUTELY.....with the smaller gauges, I' ve found bridging of the powder in the small bushings.....especially with longshot and IMR 800X

BTW Hornady is the only company I know of that makes different size bushings for different sizes of shot.

RCBS does as well (make shot bushings) and they are interchangable with Hornaday.
