.308 Dia. mixed 147 & 150 Grain Boat Tail ball bullets. Lead base 500 Pack

.308 Dia. mixed 147 & 150 Grain Boat Tail FMJ ball bullets.  Bullets are mostly 147 grain with some 150 grain mixed in but we have not found many 150 grain in spot checks, they also have a slight recess 1/16 or so in the lead base, lead is recessed from the jacket. We have seen these before in Federal bullets and this may cause a problem with the tips sticking in the bullet above in progressive loading thru a Mr. bullet feeder or other bullet feeders on automated progressive loaders.  These bullets are from pull down ammunition and will have slight pull marks on them from being pulled. Bullets are from several different manufacturers and will have a slight height variance between manufacturer .
