So...I just got my 223 World's Finest Trimmer

[Rhino0427]

I realize I'm something of a new guy, but I need help from someone who has some experience. It says to adjust them using calipers (I have some), but I don't really understand that process and I don't want to jack up a bunch of 223 brass playing "trial and error". I read somewhere that it comes from the factory set at 1.75, but I'm more of a "trust but verify" guy. I'd like to know exactly how its set before I start grinding.

Any thoughts from the experts on how to get my measurement setting so I can get to work?

I'm no help but tell me how you like it. I was thinking about ordering one.

Do you have a case that is already the correct length that you could use to set it up somehow?

I trim to 1.740 and never worry about it again.

Or trim to 1.355 and call it 300 Whisper...

That's what I'm thinking I may end up going with, but this is my only trimmer. So, I'll have to sort through all my brass to find the lucky brass that just happens to be the right length after going through the die. I'm sure there is one, but that seems a bit cumbersome when I'm sure a more elegant solution is available.

That's my plan, I just need to find a way to either set the trimmer at 1.74 OR find a 1.74 case to use as a guage for setting the trimmer. I was hoping there was a more precise process.

I just ordered one. Everyone seems to like them. I'm going to make 1000 pieces of .300 Blackout (sorry, Hoser... I know it's really a Whisper) and was looking for a quick and easy way to trim the cases.

I am thinking of getting one of these.. does it chamfer as well as trim?

No it doesn't. Still needs a light chamfer before seating.

Easiest way is if you have an existing empty case that you KNOW is the correct dimension. The trimmer 'rides' up and down the drill bit that does the trimming and is held in place by two hex screws. Loosen those hex screws so that the trimmer 'floats' freely on the bit - then put the empty case that is known to be the right length into the trimmer and make sure the trimmer fits up against the case shoulder. This particular trimmer indexes off the case shoulder, so you need to be sure when the case is fully inserted into the trimmer, the trimmer is pushed up to contact the shoulder. Then tighten those hex screws. It sounds more difficult than it is.

Let me know if this was not clear and I'll try to clean up the description a bit.

Like a lot of things in reloading, there's a little trial and error. When you start, setting up dies seems daunting. After a while, you won't think twice about it.

If you let me play with your new trimmer, I'll bring you a piece of brass that's the correct length.

Just get better beer this time.
