Converted 50 .303 into .410
Loaded a dozen with 11.5 gr Blue dot.maybe do up the rest tomorrow
I used my 9.3 FLS die to open up the case mouths.The felt OP wad and 3x9mm cork wads need less fiddling, seat well, Topped off with 1/2 oz of No.7, OS wad and Shower silicon sealant.
Am looking at screwing the wad to a 150 gr .38 CB wadcutter, patch with teflon tape to .395" and experiment- after the cases have fireformed.
Now to turn the kids loose...
