12. BARREL BREAK-IN PROCEDURE
Before a new rifle reaches a customer it has been already shot several rounds. The rifle is first
‘proof’ tested and then tested for function and accuracy by firing at least two five-round groups.
The rifle and barrel are cleaned thoroughly after each of these processes.
If the user wishes to continue a barrel break in procedure on the receipt of the new rifle, we would
suggest the following, using standard ball ammunition. The barrel cleaning procedure described
in this manual should be followed while carrying out any barrel breaking in procedure.
Shoot 3 shots and clean
Shoot 5 shots and clean
Shoot 5 shots and clean
Shoot 10 shots and clean
It is important to maintain a good cleaning regime for the life of the rifle.
