cervusman Posted May 13, 2018 Report Share Posted May 13, 2018 I want to load some 1oz target 12b cartridges at around the 1200fps. I have new Vectan AS powder, Winchester AA cases, Winchester WW12SL wads and CCI primers, could anyone tell me what powder charge I need please.

Stonepark Posted May 13, 2018 Report Share Posted May 13, 2018 Down load the vectan pdf showing their reccommended loadings. https://www.google.com/url?q=https://www.ballisticproducts.com/images/LD12Vectan.pdf&sa=U&ved=0ahUKEwi_4O2ws4PbAhWLuBQKHQuDARIQFggLMAA&usg=AOvVaw1YQqcH3gNpgaDD_A9zm1JW Quote Link to comment Share on other sites More sharing options...
biketestace Posted May 14, 2018 Report Share Posted May 14, 2018 21.5 gn Quote Link to comment Share on other sites More sharing options...
eric lee Posted May 15, 2018 Report Share Posted May 15, 2018 18GR will likely be enough using AA cases or at least would be using a Win209, do not know what difference the CCI primer might make, 21.5GR would be lively in a compression formed case.1 oz. Winchester AA HS Win 209 Winchester WAA12SL AS 18.1 gr 1200 9,200 PSI. Quote Link to comment Share on other sites More sharing options...
