Just bought a target rifle and had 3800 rounds through it

Exclusively it shot moly coated Norma black diamond

What is the favourite cleaning method for a barrel with this kind of history

Initial scrub with nylon brush and patches gives the impression of increase friction

Is this normal ?

If I don't shoot molys from this point onwards is that not advisable ?

Thanks

I used Moly bullets in my 1000 Yard any/any, and Palma rifle and in my A15 service rifle. I just cleaned them in the normal way after each match.

Never had any issues.

The advantages of Moly for me was longer barrel life [reference the Norma factory tests], being able to shoot a whole match without cleaning, or any fouling issues, and I disovered that because the bullets were less marked by the rifling they were pushed less up and down by cross winds. ie the bullets did not climb up and down the wind near as much when moly coated...

Thanks

I bought a IAAF 300 m rifle in 6th and each match is a 60 shot string so we are both thinking along the same lines thanks.
