Locking Bolt

[Kensal Rise]

Another rationale/benefit of the insert approach was production speed. It took a lot less time to fit up a bite with this system. And time is money when you're making products. The replaceable bite also made later servicing the system faster... and cheaper.

The major culprits in bite/locking bolt interface degradation are poor lubrication of the surfaces, improper cleaning, and heavily loaded cartridges. Just to name a few.

[Autumn Daze]

The bolt design from the introduction of the hammer less gun in 1888 featured a 12 1/2 degree angle for locking. This did not change over the course of production. The design changes with the replaceable bite and later the stepped bite were to allow the parts to be fitted and repaired faster.
