Alk8944,

Guns were being blown up with reduced loads of W296/H110?Where and when?

W296 and H110 give poor burning qualities when downloaded too much.Squib loads can result.Guns blown up?Where and when?Be specific.I don't think you can.

About warnings not to download,I can very vividly remember Winchester advising not to download and that was 40 years ago.What sources of information are you drawing from?
