RE: Who has tried Retumbo?
Bigcountry I have been using it in my Sendero and haven' t noticed any flames. I started at 93 grs and went up 1 gr at a time and am at 101grs right now and am starting to show primer flatting. I am using Hornady 180SSTs. I have been getting decent groups but more flyers than I want. My Chrony is not working so I don' t know bullet speed yet. I have just bought a RCBS neck sizer die to try to improve. I think that I am seating at 3.665
