??? Just started loading for this new gun.After firing the brass is coming out burnt arounrd the base.no signs of pressure.no bad primers,just dirty brass.kinda acts like the breech not sealing.

Do you mean it looks dirty around the primer?

What cartridge and what is your load?

N135 and N140 will do just that in that case. The peak pressure is not quite right. Try some Varget.
