Not Mule Deer but I had far better results with IMR 3031 in my BLR 358. 748 is just too bulky, I even had a 200 grain Hornady spire point pushed up out of a case due to powder compression using 748. My BLR, an older steel from rifle would almost make MOA using 3031 under either 250 grain Speer bullets or 200 grain Hornady spire points.
