Hello Nick,

I really like the 600s. I have one in 350 RM, one in 6.5 RM, one in 222, one in 30-30, and one in 35 REM. I sold my 600 in rare .223 caliber because it was too valuable to keep.

As my post above shows, the custom on the O3-A3 action allows for longer cartridges and the chamber has a deep throat to allow for heavier bullets seated longer.
