The chart is interesting . The marked area that states ( probably not possible - polished chamber , polished brass with grease ) . . Two of the three are very possible and what about a chrome line chamber . Is that not a way to give a surface more lubricity ? Sounds like we are getting closer to it being possible .

You don't think after firing thousands of rounds that extra 3 to 400 FT.lbs per shot will not have an effect on the bolt . I would add the 5.56 round has about 10,000lbs more pressure then the 50k in the test .
