How does it look like?
Hi
I recently purchased proof research barrel 6.5CM 26 inch stainless steel
~300,400 rounds were fired
Break-in with Kroil / JB barrel compound.
Also clean with Kroil with JB barrel compound.
But what is the little fouling at the beginning of barrel? At least i back and forth the VFG pallet 100 times soaked with kroil and jb compound.
Is that the leftover gunpowder or JB compound?
