Just received additional test results for two more Winchester Super Handicap target loads (using 1 1/8 oz. of lead). The components are the same as my first tested load, but with (a) 20.0 grains of Winchester Super Handicap; and (b) 21.5 grains of Winchester Super Handicap. The results: (a) 1067 fps @ 4692 psi; and (b) 1187 fps @ 5720 psi.
I have not tried the load yet, but on paper it looks very good. Depending on how much velocity you like, the sweet spot seems to be between 20 and 22 grains of Winchester Super Handicap. Plus, very low pressure.
To compare with Red Dot, 21.0 grains of Winchester Super Handicap should be comparable to 19.0 grains of Red Dot – about 1150 fps – but the Winchester Super Handicap load will generate about 1,500 psi less pressure than the Red Dot load. That is significant.
