The Bedfordshire Training Depot used two firing ranges. In Ampthill Park there was a 30 yard miniature range where the recruits practiced with reduced calibre .22 Lee-Enfield Rifles. The musketry instructor was Second-Lieutenant HL. Farnell.

The miniature range, Ampthill Park
The main firing range was at Millbrook and dates from the 1870s. It is likely the range was upgraded to meet the 1908 British Army standard. In the aerial photograph the butts are clearly visible (centre left). Recruits went on to use this range once they mastered the basics of weaponry. Millbrook Proving Ground now occupies the land.
