I picked up a 700 BA in 243 from someone that was having trouble chambering rounds and showing excessive pressure signs.
Long story short, removed the lead in the rifling but it has a severe carbon build up in the throat.
Leaning towards using an oversized nylon bore brush and solvent (shooters choice) to remove the ring, but not sure if this would be the best method.
Also looking for an 8"-12" carbon fiber cleaning rod that doesn't rotate (fixed).
Any recommendations are appreciated.
