Most of the archery wounding studies hover around 50% loss.Unsworth, J. W., Kuck, L., Scott, M. D., & Garton, E. O. (1993). Elk mortality in the Clearwater drainage of northcentral Idaho. The Journal of wildlife management, 495-502.
Right in the abstract: 43 elk killed by rifle, 8 wounded and lost. 4 killed by archery, 2 wounded and lost.
50% wounding rate for archery, but 4 times as many elk were wounded and lost with a rifle than bow. Pick you stat to fit your bias.
