num: 4
paragraphs: These regulations shall apply to shotguns.
METHOD OF PROOF
num: 5
paragraphs: (1) Statutory proof shall consist of the firing of two proof loads in each barrel of the firearm, together with view in respect of each firing.
(2) The firing of these two proof loads together with view shall be known respectively as barrel proof and breech proof.
num: 6
paragraphs: (1) The sender shall deliver each firearm to the Institute in a proper state for proof.
(2) To comply with paragraph (1), each barrel shall be
(a) struck up and chambered,
(b) both internally and externally smoothed, clean and free from rust, pitting, dents and bulges, and
(c) fitted to its action, which shall be finished (or in the finished state) and intended for the firearm.
(3) The Institute may at its discretion engrave serial numbers on each barrel and action of a firearm delivered to it for proofing, or require the sender to do so before delivery.
num: 7
paragraphs: (1) In the case of a firearm in which soft soldering has been used to effect a joint in a position where a failure of the joint would, in the opinion of the Institute, involve the user in danger, the sender shall satisfy the Institute that the joint is correctly and efficiently made.
(2) The Institute may at its discretion—
(a) take such steps as it considers necessary to ensure that the joint mentioned in paragraph (1) has been correctly and efficiently made,
(b) refuse to accept for proof a firearm having a soft soldered joint in a position mentioned in paragraph (1), if it is not satisfied that the joint has been correctly and efficiently made.
(3) A firearm of the type mentioned in paragraph (1) shall fail proof if the Institute is not satisfied in accordance with that paragraph.
num: 8
paragraphs: If a sender—
(a) submits a firearm in a condition which fails to comply with regulation 6,
(b) submits a firearm of the type mentioned in regulation 7 (1) and in respect of which the Institute is not satisfied under that regulation,
(c) requires a firearm to be proofed by a type of proof which, in the opinion of the Institute, is unsuitable,
(d) supplies, in respect of a firearm, informationn which, in the opinion of the Institute, is inadequate or erroneous, or
(e) fails to supply any information requested in relation to a firearm,
the Institute may refuse to proof the firearm.
num: 9
paragraphs: If a sender submits to the Institute for proof or reproof a firearm which is in such a state or condition, that in the opinion of the Institute—
(a) the firearm cannot be viewed,
(b) the firearm cannot be viewed in a manner whereby any defects, whether latent or patent, would be disclosed, or
(c) the firearm cannot be loaded or fired with a proof load except by involving an employee of the Institute in unusual danger,
the Institute may, at its discretion, refuse to accept the firearm for proof or reproof.
num: 10
paragraphs: (1) A firearm which has been marked as proofed under these regulations and has, by any process of manufacture or any means other than normal use, been reduced in substance or strength, so that the proof mark thereon does not represent the proof, shall, from the time of such reduction, be deemed not to have been so proofed.
(2) A barrel, the bore of which has been enlarged to a diameter ten-thousandths of an inch greater than that marked on the occasion of the last proof under these regulations, or to a diameter greater than the maximum diameter appropriate to the firearm (having regard to the nominal bore and length of chamber) as specified in Table I of these regulations, shall, from the time of such enlargement, be deemed not to have been so proofed.
VIEW
num: 11
paragraphs: Before a proof load is fired in it, each barrel of, or intended for, a firearm submitted to the Institute for proof shall be to the satisfaction of the Institute in relation to straightness and condition.
num: 12
paragraphs: (1) Before a proof load is fired in it, a barrel shall be gauged at a distance of 9 inches from its breech face for its bore diameter, which shall be within the appropriate limits set out in Table I of these regulations, for the bore diameter of that barrel.
(2) The bore guages to be used for the purpose of paragraph (1) shall be of the diameters set out in Table II of these regulations.
(3) Before a proof load is fired in it, a chamber shall be gauged and each diameter and each length of such chamber shall, at such gauging, be within the appropriate limits set out in Table I of these regulations, for the dimensions of that chamber.
num: 13
paragraphs: After the firing of a proof load, a barrel or firearm shall be inspected for the purpose of ascertaining whether or not any material change has taken place as a result of the firing.
num: 14
paragraphs: A barrel or firearm which fails to comply with Regulations 11 and 12, or which, on inspection, is found to have changed materially by reason of the firing of a proof load, shall fail proof.
num: 15
paragraphs: (1) Whenever a barrel or firearm has been submitted for proof, the Institute may, at its discretion, inspect the barrel or firearm for any flaw or material which, in the opinion of the Institute, might render the firing of a service load or a special load in that barrel or firearm dangerous to the user and for the purpose of such inspection may use any test.
(2) Whenever a flaw or material mentioned in paragraph (1) is detected, the barrel or firearm concerned shall fail proof.
PROOF PRESSURES
num: 16
paragraphs: (1) Each proof pressure shall be calculated so that it exceeds the service pressure by an amount between the following limits—
(a) in the case of the barrel proof, when the pressure developed is measured by an approved method at a point 6 inches from the breech face, the limits 80 and 100 per cent;
(b) in the case of the breech proof, when the pressure developed is measured by an approved method at a point 1 inch from the breech face, the limits 60 and 80 per cent.
(2) (a) in the case of the breech proof, the pressure developed at point 6 inches from the breech face shall not exceed the specified pressure for the barrel proof;
(b) in the case of the barrel proof, the pressure developed at the point 1 inch from the breech face shall not exceed the specified pressure for the breech proof.
(3) A proof pressure may be achieved by means of the appropriate loads set out in Table III of these regulations or by any other loads which the Institute may in a particular case consider appropriate.
num: 17
paragraphs: The service pressures to be used in calculating proof pressures shall be the appropriate service pressures set out in Table I of these regulations or, if service cartridges developing a higher service pressure than those so set out become available, the service pressures set out in that Table may be increased as the Institute thinks fit.
