My crank trimmer gathers dust while my new Little Crow (.223 and .308} trimmers do all the work about five times as fast, at least. A lot cheaper then the power trimmers as well. I chuck mine in a 3/8 drill then put it in soft vise jaws and lock the trigger back. Away we go!

I used a friends Worlds Finest Trimmer and was sold on this product.

Case prep is everything. I clean then, full length size and de-prime every case. Then I clean the primer pockets, trim, and chamfer necks in/out. I clean again and anneal all my cases every reloading.

I suggest everyone interested read Matt’s original blog post at http://blog.pmatool.com/. We don’t insist or even recommend trimming your cases prior to neck turning. Cases grow and stretch at differing rates and trimming prior to firing at least once (fireforming) can amplify this variance. Unless you are forming brass for a wildcat or other cartridge that requires it, there is no reason to trim prior to firing once or twice (at least no other reason that we can think of).

I like the ‘worlds fastest trimmer’ but shoulders are rarely EXACT. Just measure em, you can see for yourself.
Such an approach throws you into all that fails with StoneyPoint type OAL tools..

I’m satisfied so far trimming to the case heads.

My vote is for the Giraud trimmer. Awesome piece of machinery.
