This is a direct cut/paste from their site. There is nothing listed on their site for this powder/bullet combination.
I had a similar question for use of IMR7828 with a Sierra bullet. One of their technicians was MORE than glad to help. I suggest you call Hodgdon's customer service and ask them - sure they wouldn't mind.
wanted to also tell ya i looked in my newest hodgon manual, its not listed with that light of a bullet,one thing iv''e noticed about retumbo is it burns with higher presure, comepaired to h-1,000, ive burnt more h-1,000 and it was great,but that doesn''t mean retumbo isn''t steller i heard many great things about retumbo,one things 4 sure your gun won''t lie to you..regards jjmp :wink:
