PacNor did my 20 Grendel barrel, and I have been very happy with it.
Have talked with both makers about the chambers, both clam they do 6.5 G they call them both match and say its same reamer , Im told they do thr chambers on the deep side to allow the GS to cut the end of the end of the barrel to the correct head space for the action. both the CZ and Howa have no shoulder on barrel and seat on a ridge inside the rec. ring. the barrels Im looking at are replacement barrels not blanks. Thanks for the input and anymore would help
