sitsinhedges Posted December 30, 2011 Report Share Posted December 30, 2011 What weight of lead and what wad are you going to use? Nobelsport seem to state maximums but I have had good success with 23.5grains of A1 over a B&P Z24 wad with 32 grams of shot in a 70mm 12g case. I wouldn't want to increase this amount of powder myself and there would be no need to because it's a cracking round. 23.5 grains = 1.53grams roughly, google is good for converting gn to g. For lighter shot loads get Vectan AS and save some money. Always verify recipes Quote Link to comment Share on other sites More sharing options...

(For those who are not mathematically minded, there is no such thing as 'division!) Quote Link to comment Share on other sites More sharing options...
sodit Posted December 30, 2011 Report Share Posted December 30, 2011 Yes Useful little program called Convert gives 1.58grm = 24.38319 grains so for normal use I would call it 24.4 but I guess it is safer to go under when reloading. Convert is available free from http://joshmadison.com/convert-for-windows/ Sodit Quote Link to comment Share on other sites More sharing options...
Donkey Posted December 30, 2011 Author Report Share Posted December 30, 2011 Thanks for the replies guys I usually use hodgdon clays or longshot powders but have a tub of A1 I want to use up The load data was from the Nobel web site for use with 32gm loads I only use verified data when loading I just wanted clarification to grains I get some cracking loads from the clays powder in a CF case but it's expensive so I might try some of the vectan AS for 1oz loads Donkey Quote Link to comment Share on other sites More sharing options...
