I see there are 2 groove 4 groove and 5 groove rifled barrels. Would the the 5 groove be the best for accuracy ??? Jack
The Canadian army directed that 5-groove & 6-groove barreled rifles
could be selected for conversion into target rifles.
Wartime manufactured 4 groove barreled No4 rifles are
very rare
Bren's were made by Inglis, and No4's by Long Branch, how do they rifle LB barrels with Bren tooling?
seems a bit odd
Canadian Arsenals Limited "Small Arms Division" (commonly called "Long Branch") received
ALL of the government owned tooling and equipment from Inglis Boiler Co. when they closed down small arms manufacture in 1945/46.
CAL produced Brens & Browning High Power pistols post WW2, having said that they mostly assembled un-numbered receivers and manufactured small parts & componants (including barrels).
Long Branch 6- groove barrels (dated 1949 thru 1958) are Right Hand rifling, and are said to have been rifled with the Bren (6 groove right hand) rifling broaches.
All other military No4 barrels are Left Hand rifling grooves (2, 3, 4, 5 [& Savage 6 grooves]).
Having said that, I'm not sure that the Savage 4 & 6 groove barrels were left hand rifled...I guess I should look at my 4 groove Savage barrel, anyone got a 6 groove Savage to examine? I know that the BSA 4 groove barrels are left hand.
What manufacturers made two grove barrels other than Savage and Longbranch?
Wartime Fazakerly, Maltby & (fewer but they exist) BSA No4 rifles are found fitted with British manufactured 2 groove barrels.
