The Americans were always more prepared to use "marketing" than us reserved Brits, hence the prejudice against rear-locking actions.
The pressure in a round is limited by the strength of the cartridge case, not the action.
Rimmed case - worked extremely well to the extent that the Vickers and Lewis guns were used as scythes of men between 1914 and 18. The fact that cartridge length is not very significant in a rimmed round allowed the Short, Magazine Lee Enfield to be the premier battle rifle of all time.
The Vickers and Lewis (and the LE No4, and the Bren gun) also went through WW2 in .303 and IIRC, we won!
I believe that the steel of a rear locking bolt compresses microscopically along its length when the round is fired, whereas a front locking bolt doesn't. Hence rear locking bolts being described as 'springy'. This apparently has an effect on barrel harmonics which in turn results in front locking rifle being inherently more accurate at ranges under 600 yards and rear locking rifles better at 600 - 1000 yards. There was a whole load of plausible physics to support this explanation, but I can't remember all that. The real worry is that I also can't find the book that described it all.....charadam said:The "springy" action reference goes back, I believe to the target shooters of yesteryear.
They were trying to work out why the SMLE was capable of better performance at 1000 yards than at 300-600 (or vice versa - God, my memory!). The rear-locking action was represented as "springy" and not capable of precisely returning to battery identically every shot.
This may or may not be true ....Charles
Yes I can.....I know that WSM300 likes to go by the book so here it is....... "The Book of Shooting for Sport and Skill" 1980. ISBN 0 584 97064 1. Chapter 11 - Fullbore Rifle Shooting by Kenneth Brechin. Mr B was the Scottish National Fullbore Rifle Coach, so I'm guessing he knew what he was on about! Anyway, it is all in there with an entirely understandable explanation of positive and negative compensation.Bandit Country said:The real worry is that I also can't find the book that described it all.....
