A kit includes a case trimming assembly and a plurality of interchangeable case bearings (e.g., collets and/or bushings) adapted for engaging cases of different sizes for guiding the cases into proper position with respect to a cutter. The case preparation apparatus includes a support member for supporting a trimming assembly of the apparatus in an upwardly inclined orientation. The case preparation apparatus includes a storage container. Associated methods are also disclosed.
