I finally got a can of 5744, took a month. I started with 32 gr's and my 317 gr GC boolit. I hit center bull where I am sighted with the 4759 loads. Here are some group sizes at 50 yd's. I only loaded 3 of each to conserve boolits and powder.
32 gr's=1" 33=2-1/2" 34=2-1/16" 35= 2" 36=1-11/16" 37=1-1/2" 38=7/8" 39=1-9/16" 40=1-3/16".
Every load hit center until I got to 38 gr's and the group hit 1-3/4" high. This is where a recoil increase started to be felt. 39 and 40 gr's hit 3-1/4" high.
With the lighter loads I was getting some unburned powder out of the cases. This went away as I increased the charges.
Next is to try 37.5, 38 again, 38.5 and work up to 42 gr's. I had no pressure signs and brass fell out. Then I will try some Dacron over the best loads. When done I will chronogaph the best.
Hoping for 3/4" or under.
