  Good evening to you!! I've found listing for both 1-7 and 1-7.5 .To obtain the precise barrel twist rate for this specific model, it would be best to consult the manufacturer directly. The manufacturer for CVA is Connecticut Valley Arms https://bpioutdoors.com/contact-us/
  Hope this helps. Have a good rest of your day.

  A:

  The .243 Winchester has a significantly larger case capacity compared to the 6mm ARC. Here's a breakdown:
  6mm ARC:
  Case Capacity: Approximately 34 grains of water (H2O).
  243 Winchester:
  Case Capacity: 53-54.8 grains of water (H2O).
  Key Differences:
  Significantly Larger: The .243 Winchester holds considerably more powder than the 6mm ARC due to its longer case length (2.045" vs. 1.49").
  Potential for Higher Velocity: The increased case capacity of the .243 Winchester enables it to achieve higher velocities with similar bullet weights, resulting in a flatter trajectory and potentially greater energy at longer ranges.
  AR-15 Platform: The 6mm ARC is designed to function reliably in the AR-15 platform, while the .243 Winchester is primarily found in bolt-action rifles.
  In Summary: The .243 Winchester has a larger case capacity, allowing it to hold more powder, while the 6mm ARC is designed for the AR-15 platform and prioritizes efficient use of powder in a shorter cartridge.
