I just (3 weeks ago) got back a JES rebore in 9,3x62. It was Ruger Guide gun in 30-06. It wouldn’t hit the side of a barn at 100yds. Jess said the 3 groove would be all I need. I remounted the scope when it came back and used cheap PPU 285gr to get it back on target. It shot 1.5 or less right off the bat. As soon as it warms up I’ll be trying JB’s 250gr Accubond load.
