I had JES bore my .308 barrel to a .358 also. Overall I am pleased, but found that after the work, I struggle to feed the first round into the rotary magazine, Once I load one up, however, the rest go in easy and they feed well into the chamber as well.
I have been loading and firing 200 grain Hornady RN in front of 47 grains of Varget, getting good results.
