They should work well. Also try some 69gr SMK Sierra Match Kings. Mine favors this rd.
It took about 10 min to lap the uppers. Neither one appeared to need much lapping. It took about an hour to disassemble and reassemble the .223 upper. The 6.5 Grendel was in pieces, so I only had to assemble it.Bruce, How much lapping effort was required to square up your two receivers?
