Swaging Jacketed Bullets

I have never tried to do so with jacketed bullets - you might be able to ram a jacketed bullet through a smaller sizer, though. I had read that chances are good that the core and the jacket get separated (loose their grip) by doing so, though. I think the commercial bullet makers draw (swage) the jackets first, then insert the lead core, then various crimp / swage / etc. for forming the bullet's tip - It would be good to hear if anyone has tried to resize finished bullets and what the shooting results were like?? 0.224 to 0.204 would be reduction of 0.020" diameter - circa 8.93% reduction from start size. 0.284 to 0.277 would be reduction of 0.007" diameter - circa 0.199% reduction in diameter
 
Yes............. 8mm .323 to .32 Special .321 etc Not sure how forgiving the jackets are as there is some spring back after sizing apparently?
 
If the lead and jacket separate... You could be left with the jacket in your barrel... Dangerous upon next round fired

This is likely when someone nips the top off a fmj to make sp
