This post is for the guys who want to clean,
break-in and look for the best ammo.
Before installing the barrel,
I suggest you clean the bore with solvent.
That will eliminate the oil.
BREAK-IN
This is the break-in procedure I suggest.
For the break in, use standard velocity or low velocity ammo.
Always start from a completely clean and dry barrel.
For the first 25 shots,
1. After each 5 shots, pass a patch with solvent.
2. Use a worn bronze brass in the leade area (in front of the chamber)
with a movement of back-and-forward
for a total of no more than 8-10 double strokes.
3. Clean with patch and solvent.
Finish with a dry patch.
As I said, do this after each 5 shots, for a total of 25 shots.
That would be a total of 5 cleaning sessions.
Repeat the same procedure for the next 60 shots,
but this time do it every 20 shots.
That would be another 3 cleaning sessions.
I suggest you use a plastic-coated rod of 17 or 20 caliber.
These have their own dedicated threads, so you will need
an adaptor to use regular 22 brushes and jags or whathaveyou.
Be careful not to scratch the chamber or the crown.
FINDING AMMO
You can move now to finding a suitable ammo for your barrel
(yes, you have to do it because nobody else will do it for you).
When testing ammo, as a general good practice,
1. start at 25 yards, as it will make it easier.
2. mark the paper with the type of ammo, distance,
wind, conditions, etc., because you will forget these details.
3. Keep the target paper with all that info (even if
the results of the test will not be satisfactory).
4. Also, before changing ammo, give the barrel a quick cleaning,
5. Allow few shots until the new ammo will “season” the barrel.
Some ammo will do that seasoning in 10 shots, other ammo will need maybe 50 shots.
