Hello,
Other than holding the bullets secure the amount of neck tension provided by the same sized neck bushing as the fired neck diameter yeilded no difference in accuracy.
I have been experimenting with wads, paper wet/dry, powders and various combos of anything I could think of and have come to two loads that are eauqauly accurate to 1k.
Both loads are the constructed the same other than powder charge.
Swiss 1.5, 71 grains dropped directly into case - 78 grains dropped tubed into case.
BR2 primer.
.060 veg wad, matriarch from BACO punched out on a press punch. Bottom of wad compressed to bottom of neck.
.070 cork wad, gasket material from Felpro punched out on press punch and pushed down on top of veg wad.
500 grain swaged Creedmore style cup base bullet of pure lead dry patched with .002 onion skin paper
Will get some pics taken and posted this next week after I get some more bullets smashed.
