The ammunition used in the Khyber Pass region is often underloaded, being made from a variety of powders or even old film (which contains nitrocellulose, a key component of smokeless powder); Khyber Pass Copy rifles cannot be expected to withstand the pressures generated by modern commercial ammunition. A few collectors have made extremely mild handloaded cartridges for their Khyber Pass rifles and fired them, at substantial personal risk.
