I've just spent a sizeable part of my last two evenings prepping cartridges for a competition this weekend.
I have recently confirmed a low to mid-power charge of 8.5gr N320 under a 200gr LSWC to emulate my .44Spl load with 7.3gr of the same powder under the same bullet.
40.70mm OAL for the mags, 36.80mm OAL for the Specials.
My question is this. If I load my Special cases with the same 8.5gr mag powder charge, and seat the bullets to the same 40.70mm OAL, can I expect similar performance?
The bullet, charge, primer and air would all be the same.
The only variable that I can think of is about 20% less bullet surface in the throat of the case and thus less stiction to overcome on ignition. Enough to make any discernible difference?
The idea is to have the magnum length of the mag cartridges, making for wasier reloads, while still making use of my Special cases.
