Sieger,
All I know is from another forum, where they quoted Chris Hodgdon as saying this in response to being asked about 4756 being discontinued:
Yes this powder (4756) along with 4759, PB and 7625 will be discontinued by the end of 2014. I can understand that you are disappointed but there are many reasons why we are discontinuing including outdated technology, high manufacturing costs and low sales.
Appreciate your interest and business
