I use the Redding competition bushing die set. My brass has 14 plus frings on it and never below 90 gr of H-1000 with a 300. Most loads were 92.5 gr. All is still good there. However at one time I was not getting the shoulder back quite enough and in that instance I would get a harder bolt lift (after fire) and sometimes a slightly stuck case. Once I moved the shoulder back another .001" this went away and all hase been good since. Now I do a controlled body size every time and do the necks in a seperate step as well. My velocities from a 27 1/2" tube are 2800 and right in line with your stated velocities.
I only post this to back up your process and to support your load data. The only thing I can think of would be your sizing could be a little on the weak side resulting in a similar issue as I had.
