2. Introduction
There have been few developments around the in many years.
Most Rifles are lever action.
Lever actions inherently have exposed hammers and many moving parts.
Space concerns and inherent danger with exposed hammers.
Lever actions can be difficult for inexperienced shooters. Especially older models.

3. Introduction—Contd.
A Bolt action would eliminate the need for an exposed hammer by having firing components contained within the bolt.
This makes them inherently safer than their lever operated counterparts.
Problems arise when rimmed rounds like the are considered. Primarily due to their pronounced rim, which often catches on the followers of traditional box magazines.
The rim and the blunt nose of the round are the reasons behind tubular magazines being ideal for the

4. Objective Create an optimal design for the .30-30 Winchester.
This design will utilize a bolt action rather than a lever action.
It will retain the tubular magazine running under the barrel.
The chief idea/objective is to retain the pros of both types of actions while eliminating their respective cons.

5. Design Challenges
Action/Mechanism must be designed to reliably and safely complete the firing  ejecting  feeding  reloading cycle repeatedly until magazine is empty.
The chamber/barrel/headspace needs to be designed to handle a variable working pressure with a maximum of 42,000psi (290Mpa).
Internals must be able to handle the many stresses applied by the different individual movements of metal parts within the action, as well as impact loads during firing.
Custom barrel, magazine assembly, receiver/housing and internal mechanisms must be designed and adapted to meet a standard bolt and trigger assembly.
The whole system should be light and compact, with internals that are simple and reliable, and made of specifically selected materials.
It needs to be easily disassembled for cleaning, and need little maintenance to function smoothly.

6. Deliverables Conceptualize and complete rifle/mechanism design.
Compile all necessary data.
Complete all necessary calculations.
Choose best material(s) based on calculations.
Build assembly model prototype in SolidWorks.
Complete analysis of all parts in COMSOL.
Total build cost estimation.
