Thankyou Daryl

So as i thought, this is a job of sending the barrels away,or getting the gunsmith to do it? Dont much fancy doing it myself anyway!

Where does pitting matter most,on the lands or grooves???

Does this 'metaloy' fill the pits,or just coat everything thinly?

I pictured that one puts it down the barrel, it turns stiff/hard,then a die of the right bore is put through the barrel,and hey presto, no pits, fully lined clean bore......is this possible,impossible,or???

Thanks

Ben
