Cumbria reloader

Thanks Dave at Kelton. Sounds about the same as I'd tried though. Might cut a case down in length and try a firmer wad to better match Alan's load. I think packing out might risk changing the ballistics, eg extra friction and more column to compress until lead gets moving, I.e. pressure could spike(?). Thanks.

Hi, looking for a recipe for mild clay load in 10 bore using bluedot, Remington hulls and cci209m (cos I happen to have loads of each) but all aliant recipes use plastic SP10 wad. I have SAM1 wads- anyone have experience of swapping them? - but in any case clay ground insist on fibre wads. Couple years ago I tried using wax coated cork wads like I do for B.P. rounds and the primers just blew the whole shot column down the barrel without igniting the powder. Whoops didnt realise wads made such difference back then! Guess cork too soft or not enough roll turn over. Looking for someone that knows more than i do on the matter, thanks
