In December 1836, trials were conducted to compare the Brunswick rifle against the Baker rifle. The Brunswick rifle proved to be equally accurate at shorter ranges, and more accurate at longer ranges. The Brunswick rifle also proved to require less cleaning than the Baker rifle. Evaluators also noted that the simplified two groove design of the Brunswick was likely to have a longer service life than the barrel of the Baker, and the Brunswick rifle was noted as being very rugged overall. In January 1837, the rifle was approved for production.
