I recently got into reloading and bought a ton of once fired brass. After I trimmed 100 cases with my Lyman hand trimmer, I put my glock up on the EE and placed my order for A giraud power case trimmer.
It is apparently the Cadillac of case trimmers. Trims to length and chamfers inside and out all in one easy step.
I can't wait to get my hands on it and finish trimming the 1000 pcs of brass I've got.
