Brass trimming !

Here is another thought about case trimming. I use a Forster Bushing Bump Die on my Lapua 6BR brass. I did the initial square up trim with a hand Lee trimmer. Since that time I have reloaded 5 times and they have not needed any more trimming. With the bushing bump die, I only resize about 2/3rds of the neck and bump the shoulder 0.001". I load them pretty hot, but with this method of sizing, they don't seem to grow. YMMV...
 
I have a Giraud and have my gunsmith make custom caseholders using the same reamer as the rifle. Super snug fit and no need to FL size.
Expensive, yes, but very consistent trim length and super fast.
 
Why is the Giraud trimmer so expensive? Because it's worth it in terms of the labour savings.

If you are looking for a lower cost option, I would consider the Trim-It II. It's a drill-mounted tool with interchangeable case inserts that cuts and chamfers at the same time.

Lee Deluxe Power Quick Trim all the way for me. I set it up in a spare press. I replaced the flimsy adjustable dial thingy with a stack of washers from Home Depot. The washers are all .030" in thickness. You stack them up to the correct length and fine tune by sanding the last one to the proper thickness. This way the cutter repeats the correct length every time within a couple of thousands. I have mine set just under max SAAMI in .308. Great thing is if you have different sleeves for different calibers they're all going to be the same few thousands from max too.
 
exact way I use mine. Set the depth stop and you're not even putting pressure on the pilot/gauge.

I'm quite impressed with my setup, enough that I've cancelled my plans to purchase a up-market electric trimmer, and haven't used my Lyman trimmer in severL YEARS.

I still shudder thinking of my first experience making 8mm lebel revolver brass from 32-20 cases. Trimming a quarter inch from each case on 200 cases with a Lyman manual trimmer was almost more than I could do - came very close to pitching that trimmer in the garbage can.

Laziness is the true mother of invention. Whoever said "necessity is the mother of invention" was full of crap.
 
This is how I trim my .223 brass. It is a Giraud Tri-Way trimmer mounted on a single phase 1725rpm motor.
