Anyone have any luck with Imr 8133 . Looking for any loads for 7mm and 28N . I hear it is supposed to be in comparison to Retumbo. Thanks
Happy to of found this post ,sent you a PMIn my 7WSM I got pressure signs before I got close to advertized velocity. Highly compressed loads which I don't like. ES and SD not good either. Higher velocities, better ES and SD, plus better accuracy with Retumbo. Still compressed loads tho, but not as bad. I had great hopes for 8133 and 7977 because of the temp stability and the copper scrubber, but neither worked out for me.
