4 rounds from a privately owned Boyes .55 ATR, black and blue for days.
110 rounds in 1 shoot of No 4 Mk1 Lee Enfield .303 at Wrekin Ranges before the whole army's stock was decommissioned. Black and blue again.
Ex argentine FN FAL 4 mags on full auto, that was just funny trying to get even the second round of the burst on target.
