Shooting at 232 yards with a Marlin 336w 30/30

Shooting on a can at 232 yards (length measured by my brand new 100% Chinese rangefinder) instead of 245 yards which was the total length of the range, with a Marlin 336 30/30 "out of the box" equiped with an old Tasco World Class 3-9X40 scope made
me dubious .
Is it possible or not ?
I made my own rounds with Sierra 170 FN with a light crimping .
It's almost easy to do at 110 yards but it's a bit different at 246 yards . I improved my round by using the Hornady Concentricity Tool and I made the difference with it .
