Hello,

I had given up on a 28 Nosler rifle that was shooting innaccurately. It is heavy recoiling and I thought it was just me but I decided to get a cheap bore scope to take a look before contacting the manufacturer.

This is after much cleaning using
-BoreTech Copper Remover (there was a good amount of copper fouling)
-BoreTech Carbon Remover

The copper and carbon cleaned out quite easily but there seems to be lead(?) fouling? I cant find much information googling this, and it's definitely raised, so I wouldn't say it's pitting. Is this lead, and what would cause this?
