I just acquired a 10 gauge 2 7/8" Francotte SxS and will need to load for it. I plan to use Cheditte hulls and primers. Ballistic Products has primed hulls in 3 1/2" that need to be trimmed. I plan to fold crimp. I understand there are homemade trimmers, but I like the ease of use and convenience of the commercial made ones. Has anyone used the ones below? The Creative has to be special ordered to cut 2 7/8", but it makes a very clean square cut. The pilot rides in the spent primer flash hole, which is a problem with already primed hulls. The GAEP can cut 2 7/8" and the barrel is interchangeable with all gauges. The cut is not as nice as the Creative and I've read doesn't work as good with tapered hulls, which isn't a problem with Cheditte.
