I changed out 2 barrels a year while competing regardless of the round count because I had a place in line with a super gunsmith.

Keep your powder charge near the top of the node not the middle or beginning and seat all your rounds to within 0.001 of each other using a comparator.

The variation you will see is coming from the bullets and it is an eye opener. I have seen 0.023 variation out of a box of 100 bullets.

If your shooting a 6mm try a box of 103 VaporTrail bullets or the ones made by Randy Robinette if you can get them. If not give the Berger 105 BT bullets a try not the VLD or 108's.


Someone asked a question about CM barrels lasting longer than SS barrels.

While your accuracy needs are measured in parts of 1/10ths, I am ok with a couple. I have had a lot of factory CM barrels but none that shoot much better than 2/10s (just at and sometimes above 1/2 MOA)

It seems lasting longer is just that, so I see no advantage to CM, just worst longer, unless used in auto fire. But I have no idea in precision rifle, it is just a guess. My CMs spin off fairly fast.

Can you ahead light on the truth?
