found out another thing this evening when i was rolling some for try outs next week.
in house i had somewhere a perforator , that is used for punching holes in paper.
turns out that the paper "disks"in the reservoir is the same size as the bottom of my bullet , so i took some , wet them in water and sticked them to the bullets base.
then i patched the bullet the same as the first ones i did.
i think it would be a nice protection of the base , and i can even put in a carton or
maby some thicker , stronger paper.
so , another thing i have to experiment with....
i patched 20 bullets this evening , 10 of them with the core sized at 6.45 mm,
and 10 of them with the core at 6.50 mm , the difference is like 0.016 ".
lets see how this works out.
