Built my 10mm PCC only to find it has a FTF.  It has been to a gunsmith and he determined that there was too big of a gap to jump from when the bolt carrier picks up the cartridge from the magazine and delivers it into the throat of the barrel.  The cartridges get part way in then jam. He could get it to shoot with round nose FMJ bullets but no hollow points. Recommended a different bolt carrier.  Does this sound correct? Aren't  all bolt carriers for this 10mm the same?  Thanks in advance!
