Brass trimmer

Little Crow???? Couldnt say a bad thing about them. Fast trimming and easy setup.

I got the Frankford Arsenal precision trimmer. It might not have the build quality of the others, but works well and does multiple calibers.

I had one and got rid of it along with other systems. They are not bad but not as accurate for super consistent reloads regardless
of the casing and dies you used.
Over the years I have found that most accurate way to cut and trim brass is the forster 3way system (trim, chamfer and deburr) with
their long trimmer mini lathe attached to a power source like a cheap variable speed drill that also makes it the fastest most accurate
cutter.
The mount and 3 way head is essentially designed to cut based on case length just like the regular trimmer and not indexed
from the shoulder like others.
It is also less expensive to cover any calibers in a fair nr. of bores since only the pilots are needed.
To achieve the fast speeds one can build a simple carrier using a piece of board where you mount the trimmer and then
just slide left and right to do the cut. Changing to any calibers takes only a minute.
Most people do it wrong so instead of moving the power you keep that stationary and instead slide the entire trimmer
in.
I also had the RCBS and 3 way cutter but, while it is decent still doesn't give the precision and consistency of the Forster.
In occasions I have been able to prep 500 match cases in a couple of hours all with cuts within 1-2 thousands with a perfect
3 way cut.
