The leading problems that I experienced with N310
powder and 38 Special cases were just as serious with
357 Magnum cases - I tried these to see if reducing
the bullet jump from case to chamber throat would
improve things. My chosen load for the Magnum cases
was 3.5 grains of N310 behind the GECO bullets and
this gave about 800 - 830 ft/sec. There was very
little to choose in accuracy between the two
loadings - I shot my best ever group with the 357
Over the years I have conducted many ransom tests with wadcutter bullets and
.357mag cases, in every case the group size was larger than when using
.38spl cases. I put this down to the fact that when a .357mag case is used,
the bullet base is still in the case when the tip is entering the rifling,
thus any tolerance in the cylinder/bore alignment causes a distortion of the
bullet. Perhaps this is why the top 1500 shooters use .38 cases and not
.357.
Keepup the good work
