I have to agree that "best" phrase is a loose term. But then if you ask that without a definition?
So I will add in, accurate and as fast as possible, I am not one of those re loaders that like bench time, I like to shoot, not load.
I won't say I hate reloading, but it does not give me any kum buy yaes (however that is spelled). So I want to spend my time where it counts in accuracy (again where that is is my opinion)
Off the shoulder trimmers are what I wanted. Accurate and fast.
While I could be wrong (far from the first time) I don't fathom that .005 length is going to make any difference (if its too long yes, but trimmed back to nominal?)
So yes, if you ask me, best trimmer is Gerard then Little Crow/Trim It II
Gerard is tops for its simplicity, exception operation and three way
Little Crow WFT and Trim It II are second place to me as the WFT is not a tri trimmer setup (otherwise it would be 2nd) and Trim It II is too complicated and lacks the precision of Gerard.
More or less I put the WFT and TITII
1. Hunting: WFT, lower cost, a bit of work with a chamfer and deburr not a bit deal
2. Trim It II: In the case that Gerard does not make a Tri Trimmer for and you don't have the Motorize Gerard setup that they make everything for.
Until I ran out of my killer priced Juggernauts, I was shooting 1/4 in groups with Trim it II bullets in the 7.5 x 55 Swiss Savage I built.
I do shoot 3/8 inch groups regularly with the Gerard trimmed brass, often flirt with and do get 1/4 inch groups.
Give me David Tubbs gun and I suspect I could manage 1/4 inch groups all the time.
