Yes this will shoot CCI standard but it's more expensive to shoot.
Mine was manufactured in 1982. I removed the bolt for the first time and compared it with an NOS one because the nos bolt holes were gritty. Whether this is by design to catch carbon I don't know.
I have drilled holes like that after discovering I used the wrong speed on the mill or drill press or a bit that needed resharpened.
I used pin gauges to check the hole sizes on both bolts.
They only varied .001 but the holes were slightly scored on both.
The spring for the ejector did not move smooth in either bolt when the pin was moved.
So I ran reamers that were .001 larger than what the pin gauges indicated to polish the scratches without enlarging the holes.
When tested it felt smooth without the gritty feel.
One bad apple can make the whole barrel SMELL.
