Interesting question !
... Considering this is a Canadian site, naturally there's more interest in the "Longbranches" than any other manufactures. That being said, it's not unreasonable to assume that the quality of the steel/metallurgy of the Longbranch No4s was superior to other No.4s. Made without the interruptions of Air raids and uncertain supplies. I would also assume that to a lesser, perhaps, extent, the Savage No.4 rifles would have had a high quality of materials as well. ..... as to accuracy, well, that depends on the individual rifle to a large extent, but the average rifle, that would be an interesting subject for unbiased research! And I doubt that there would be any conclusive answers! Even the debate of 2 "groove" rifling vs 6 "groove", shows no definitive advantage. ..... Bear in mind, the "T" (Sniper) rifles, were 'selected", so fall outside of the average Enfield No4. ..... David K.
