Here is waht I have come up with so far with the ski plugs. Mine must be a different mfg as they seem to look more rounded then pointed at the tip like the purple ones Duke posted.
They are soft and my ejection pin is .093 so mine are a bit more blunt then algun posted.
Bullet is .224 of course at 57 grains. Looks like I'm going to have to find some better ski plugs. Mine where not connected but came in a 500 count bag.
I may have been able to apply a bit more pressure to actually swage the plastic a bit more but my die needs a good polish as it was easy to deform the tip when I applied to much pressure.
Looking good guys.
