Lyman Drill Press Case Trimmer
Does anyone have any experience with this piece of equipment? I have decided to get one, but have concerns. My current case trimmer is a lyman, and the little screw that held the pilot was so soft I destroyed it the second time I switched pilots. It caused a major inconvience. I think this has the same set up but this time I will replace the screw with a high grade bolt right out of the box.

If it works as designed it should allow me to uniform brass with great speed and precision. If it doesn't, it will just be another $50 piece of junk.

Thoughts?

I have and use this unit with a Jet 14" press. It works like a charm, although I will say that it is a bit of a challenge with .348 Win brass. The rim is almost too large to function right. For .22-250, 6mm and .338 Win, it works perfectly. Just get the carbide cutter to go with it, it will save you some time.
It is actually cheaper than an RCBS unit in which you need to buy the different shell holders.

I have no experience wih the Lyman case trimmer.

But I have used the Lee Case Trimmimg system extensively, and I recommend it highly. (I think this is one tool -- there may be others -- where Lee has succeeded in making something that is superior to other manufacturers.)

The system consists of a cutter and lock stud, which are universal -- you need buy only one as the same one is used for every caliber -- and a case length gauge and shell holder. You need to buy a new case length gauge for each caliber -- they cost less than $5. Different shell holders are needed for each different diameter case head: i.e., the same shell holder is used for all the 30/06, 308, 7x57 etc. based cases; a different one is needed for the belted magnums, still a different one for the 223, etc.

You trim the cases after they are sized. The case length gauge threads into the cutter, and the case is put into the shell holder; the lock stud threads into the shell holder and is screwed down to fasten the case tightly in the holder. Then the case length guage is put into the mouth of the case and a pin on its end goes through the flash hole and is stopped by the lock stud. You can then turn the assembly by hand, or, as I do it, put the lock stud into an electric drill and use that to spin the case, while you hold the cutter assembly stationary.

The beauty of this system is that it's quick, efficient, and inexpensive. It trims cases to the same length every time and squares up the case mouths. The only disadvantage is that you have no control over the case length, but then who cares? The cases are trimmed to the same length every time. I use this system to trim my cases after every firing, thus they are of consistent length.

While you have the case spinning in the drill, after trimming, you can also chamfer the indside and outside of the case mouth with a chamfering and deburring tool. (I use the RCBS tool; I think it's made by Wilson.) You can also use steel wool, or a solvent impregnated cloth, or whatever other means you like to clean the outside of the cases too, if you want to do so. (I found that Remington Brite Bore solvent works very well.)
