This is the Enfield (.303) action. The presenter explains why this action is a very fast action to use enabling very quick repetitive fire. The actual firearm is not an Enfield built rifle but an Enfield action. It is not chambered in .303 but originates from that calibre. It is all about the ergonomic design.
note: the maker of this firearm is no longer in business.
Faster repetitive fire because:
- No need to reposition the hand to fire after working the bolt.
- You can maintain good grip on the bolt and fire at the same time
- Rear locking lugs shorten the throw for faster reload
Enables constant targeting because:
- Low radius of cam action - 50 degrees means no need to move the head. Shooter can maintain sight picture.
- Sights not obscured by bolt action
More stability of the rifle assisting in maintaining target because:
- Cocking occurs during the locking cam action, not on the outstroke
- Spring compression on the instroke when force is being applied (anyway) to drive the round and cam the bolt into lock.
- Not pulling against the spring on the out stroke which results in more force being required and more movement in the firearm pushing it off target
probably other good points I missed
