Case trimmers.

[NF1E]

Have been using a Giraud trimmer for years and it works great. Trims, cuts outside and inside case mouth to the correct angle. Well, I have this old Lyman power universal trimmer in the shop that I use for straight walled cases and thought , Hummmm, how about bringing it into the 21 Century with a 3-1 cutter. Found the Forster 3in1 was an easy fit after turning down the OD of the Lyman cutter, it slipped over and locked down with the allen key. When I want to go back to the old setup, I just unscrew the altered cutter and pop on a new one. Can't get much easier than that. Whatta Hobby!
