In a departed Ruger 77 Mk II IMR 7828 ssc did very well with 140 gr PT's at around 2775 fps if I remember right. In my wife's Tikka IMR 4955 is showing promise with 140 gr PT's at just under 2700 fps. It shoots well but I still might tweak it a bit.
I have some 4955, tried a little of it in a Ruger 270 Win over the weekend. I am not sure what is up with the lot but the starting charges were ultra hot.. To the point of losing primers. First time that has happened. Might have to go back and get 8lb's of the stuff..HA!
