Cast Lead Thread ?

[T.FOYE]

I had some like this in 308, just pushed one edge down with screwdriver so it rotates and can then pull out with needle nose pliers. May depend on how much airgap there is

That very nearly worked. Then plop. in it went. Ah well, no worse off and at least i can save the powder and primer.
the needle nose plier trick may still work if i can get purchase holding this all upsidedown. Grrr how FREAKIN annoying.
This all happened as i decided to use somebody else's quickload readout. How can GRT and QL be so far apart on this???

But for me, i'll err on the side of extreme caution as firstly, I'm crimping and that adds who knows how much extra pressure. On the other hand, this is a PC soft lead round so it might behave with less pressure (less friction) down the barrel but initially it might not. None of that is considered in either program. So I'm setting my target of 2100ft/sec, estimating 22.8gns of 2207 to get me there and starting with 20% less. I can see i need to find some 2208 asap
