Idealised simulations of turbulent convection in the O-burning shell of a massive star are performed in $4\\pi$ geometry on $768^3$ and $1536^3$ grids, driven by a representative heating rate. A heating series is also performed on the $768^3$ grid. The $1536^3$ simulation exhibits an entrainment rate at the upper CB of $1.33\\times10^{-6}~M_\\odot~\\mathrm{s}^{-1}$. The $768^3$ simulation with the same heating rate agrees within 17 per cent.
