I hate to open another can of worms but Ive got a Q about barrel break-in. I'll be taking my Howa to the range soon (finally) and honestly Ive probably read 100 different ways to break the barrel in. I'll be using Tipton bore guide, rod and jags and have Hoppes BR copper solvent and every M pro7 product they make including their copper solvent. What do you guys suggest?
I sell barrels so it can be argued I have a vested interest in helping shooters use up their barrels faster.
I DO NOT RECOMMEND ANY SO CALLED BARREL BREAK IN.
I have shot a number of rifles both factory and custom barreled, brand new and "lightly used".
In ALL instances, shot and clean as a break in procedure did nothing vs just shoot and clean it when needed.
A barrel WILL find a level of break in all on its own and it usually takes quite a bit longer then the typical 20 to 50rds used as the break in process.
Clean it well the first time out as the rust preservative typically used is tenacious. Shoot it, and clean it after say 20rds.
If there is alot of copper, then you know you have a typical rough bore. Start taking notes on what happens next.
Clean the bore till lilly white - strip it of all copper or fouling as you see fit.
Now shoot 3 groups of 3 to 4 rds each. Did the groups shrink as you shot?
If it got better then found a level, shoot a few more groups and see if groups stabilize. It should
Clean it to bare metal again and see if the pattern repeats. you will quickly see a pattern of large groups then shrinking rapidly after so many shots are fired. Then the groups are stable for whatever time you want to shoot.
After a few cycles, you will also notice that the amount of copper fouling DROPS. It may never stop but the amount will reduce.
The reduction of copper typically happens after 200 to 500rds are fired. This is when I consider a barrel truly broken in.
I shoot to as many rds as the barrel will tolerate - for most barrels, even those that show ALOT of copper, this number of shots is way more then usually spoken of.
Then clean only enough to restore accuracy. You know you have cleaned too much if it takes more then 5 rds to stabilize the groups.
Some barrels will be/MUST BE fouled in order to shoot with any decent performance.
It is up to you to find out the quirks of your barrel.
YMMV.... Enjoy your new rifle.
