Hodgdon has data for it with 120 to 175gr bullets. IMR 4955 doesn’t seem to be very popular so I’m not sure how many people with actual experience with it will chime in. It’s very similar to H4831 and RL23 on burn rate. It will be a good powder and I would recommend starting with Hodgdon‘s data and working up from there.
