No, too much reduction.

I reviewed 4 or 5 different rifles when the BOSS Unit was released and found with the Browning in particular, with its very light barrels, some charges were slight barely turning the Boss unit which is why I stated 1mm or .040" as a measure point.

That was not an OAL adjustment, it was meant to be a die movement which will be less in OAL as an adjustment. I have a Model 70 Featherweight in 7x57 which made obvious gains with only .003 taken off the OAL.

You are in a position to take your loads to the range with your press and seating die set up and drop them 2-4 thou per group. You will be pleased.

When truth is ignored, it does not change an untruth from remaining a lie.
