5R-Twist Posted March 13, 2014 Report Share Posted March 13, 2014 Hi All Just been given some superformance that I may try as a replacement for H4831SC in my shehane has anybody had any dealings with this powder. It seems to be a very close burn rate to H4831SC. Thanks V Link to comment Share on other sites More sharing options...
hangfire Posted March 23, 2014 Report Share Posted March 23, 2014 Hi there has been quite a lot of discussion on this powder the only thing I can tell you is no help at all, 1 it is not the same powder used in Hornady Superformance ammo, and two there is no published data for the powder Link to comment Share on other sites More sharing options...
5R-Twist Posted March 23, 2014 Author Report Share Posted March 23, 2014 Hi there has been quite a lot of discussion on this powder the only thing I can tell you is no help at all, 1 it is not the same powder used in Hornady Superformance ammo, and two there is no published data for the powder Hi hangfire Ive now done a fair bit of testing against vit160 in my shehane and found it performs almost the same i.e. 56-57gr of vit160 gives 2923-2971fps the superformance gives 2917-2967fps at the same grns. When you look on the burning charts it seems H4831sc-vit160 and superformance are next to each other. It seems quite clean as well its also easy to meter as its so fine but time will tell. Its available as well Hope that helps someone. V Link to comment Share on other sites More sharing options...
