5744 is used a lot in large cases with partial filling of
cases with powder. But you can't fill the large cases to
90-100% as pressure climbs to much in big cases

Others tested 5744 and it is ok up so far. Shotgun cases are
in the realm of large cases. It works with wads,
to take up air space ok, but you can only get half the weight
of 4759 or 4227 loads before peak pressures are too high
above the limit that we want, which is about 15000 psi in
12ga.And still not get velocities that 4759 and 4227 get.Ed
