and just like the WFT setup... you still have to debur and chamfer afterward.

the lee trimmer will do the same # of cases in about 2/3 the time and you're already chamfer and deburred too.


not knocking the lyman setup, just that its a one trick pony, like most of the trimmers out there.

Lyman Universal with a carbide cutter for heavier cuts and cartridges that I do not have the Wilson collet for yet.

The Wilson trimmer for finish work.

I bevel the inside flash holes so I need an accurate case length to get consistent debuts there.

In mostly bolt gun shooting, cases are neck sized (Lee Collet die) and they grow rather slowly. It is a long time before I have to trim again!

like was mentioned, new primers will fall in and out before the case needs trimmed.

that is throwing the books out and knowing how long the case can actually be before it needs trimmed. i guess if you dont know that, you probably should trim. lol

I can agree most chambers are long enough to let the cases grow above max. My bore cam tells me that by the carbon ring left in front of the case mouth.

I will ask this, and have always wondered but never spent the time/components to test. Does/can varying case lengths affect accuracy at all? Say they vary 10 thou from minimum to maximum book length. I would think it could, but haven't done anything to prove it one way or the other.

not enough to get worked up over. not even a little.

as noted further up in the thread... if you crimp.. having a consistent case length is going to be critical to getting a consistent crimp on said loads. so while there's validity to the fact that many cases can probably do without it, there are specific cases where trimming really makes sense and is almost manditory.


such is the fun of reloading though - we can cater our process to suit our individual needs for each of our very unique firearms smile

Same with annealing, nothing to get “worked up about”?

What’s a long, short or brittle neck between shots?
