Craig, the most recent 5744 report I recall was posted by Brent Danielson on the Double-Gun-Single-Barrel Forum about 4 years ago.  Brent bought a Low Numbered 1903 Springfield sporter in .30-06 done by some big name custom rifle guy from Michael Petrov's estate auction.  IIRC, did not check, he loaded heavy cast bullets and a pretty stiff load of 5744 as a deer load.

On the first shot, the action shattered, cut Brent's face badly.  Shooting glasses saved his eyes.  He posted pics of his face, maybe the wreck of the rifle.  Brent is a very well-informed guy, a careful experimenter, very much a traditionalist.  I was astonished at his report.

Before that, I thought we could shoot cast bullet loads in Low Numbered Springfields without any problems.  No longer.

The loading data for 5744 is much like the old & much-missed HiVel #2, except that you could load HiVel #2 in anything and it would work, probably be accurate.  5744 isn't like that.  It seems to get wonky at high pressures.

The consensus of the single shot guys is to save 5744 for straight-walled cases & lead bullets, never use an over powder wad, not on the powder, not a bit above the powder, and don't even use case fillers, not even kapok.
