RyanMc Posted June 28, 2022 Report Share Posted June 28, 2022 Incorrect stack height of components? Nothing to support the crimp then it fails under the crimp pressure? Quote Link to comment Share on other sites More sharing options...
222mark Posted June 28, 2022 Report Share Posted June 28, 2022 What cases are they. Try a different make of case to see if it still occurs. Quote Link to comment Share on other sites More sharing options...
hawkfanz Posted June 29, 2022 Report Share Posted June 29, 2022 if its just an odd one,maybe base wad is smaller volume leading to incorrect stack height,they do vary a bit sometimes.try setting press up with a factory load on final stage, Quote Link to comment Share on other sites More sharing options...
Gas seal Posted June 29, 2022 Report Share Posted June 29, 2022 Hi Tony the case could be a bit longer than stated, or it could hold more volume than other cases. You could try filling one with small shot and see if it’s the same volume as other same length cases. Could you show a photo of the crimp.

snow white Posted June 30, 2022 Author Report Share Posted June 30, 2022 Hi lads I think I have sorted the side buckling but I can’t get rid of the small hole in center of crimp I have played about with the settings that I have settled for the small hole unless somebody can help out . what I done to get rid of buckle was to reset the press from scratch and it seamed to work. Thank you all for your input on this Quote Link to comment Share on other sites More sharing options...
dipper Posted June 30, 2022 Report Share Posted June 30, 2022 Try deeper crimp starter .I sometimes punch some paper discs to put over shot or thin cork discs . Quote Link to comment Share on other sites More sharing options...
snow white Posted June 30, 2022 Author Report Share Posted June 30, 2022 Shot not dropping out but I would like to get it a bit better Quote Link to comment Share on other sites More sharing options...
Gas seal Posted June 30, 2022 Report Share Posted June 30, 2022 Hi Tony have you weighed the shot. It could be a bit light . Are you using felt or plastic wads. If you are making a lot of cartridges it’s time consuming using packers. The hole in the crimp looks like the crimp could be a bit deep. It looks like you need a bit more wad hight.

It looks like you need a bit more wad hight. This. The case isn't full enough so that the crimp lies "flat". Either more shot or an extra undershot card wad between shot and the fibre driving wad. If not maybe a cork overshot wad (like the original Eley Waterproof Grand Prix plastic cartridges) that will shred when the cartridge is fired.

Gas seal Posted July 1, 2022 Report Share Posted July 1, 2022 If a cartridge doesn’t look right chances are it’s not right. If the powder and shot are correct maybe a longer wad could be needed. It looks like the shot is (loose ) in the case. Let us know how you get on . Quote Link to comment Share on other sites More sharing options...
