Gracey trimmer ?

I have one and love it so my ? is this how hard is it to change calibers ? I read the instructions but have not tried it yet,

Thanks,Keith

I bought one a few years ago to trim my .50 brass. (Gracey Trimmer (http://www.matchprep.com/))
Works OK, but adjusting the blades is a pain and they needed replacement after a 1k cases or so.

You basically, unscrew the case bushing for one caliber and screw in another for whatever your going to trim next, and readjust the two blades to the desired cutting angles on a sample case.

Unfortunately, the Gracey .50bmg version is unique, and won't interchange with 'smaller' calibers. I'd have to buy another to do lesser cases.

Ended up going with a Giraud (giraudtool.com (http://www.giraudtool.com/)) and it works MUCH better. Easier to change out caliber convesions too. More expensive, but well worth the price.
To switch to 'small' calibers, you do have to switch the entire cutter head, but they are fairly inexpensive compared to buying a whole other trim unit for the Gracey. Otherwise, just replace the case bushing, insert a sample case and adjust the single carbide blade to the case mouth and tighten.

Giraud also makes an upgrade package for the Gracey. I got one for mine and it makes a world of difference. Good instructions, but only recommended for the 'handy' with a good selection of power/hand tools and rudimentary electrical knowledge.

Mine came set up for the 223 and it works like a champ. Will I need to adjust the cutter blades for the .277 and the .308 cases ?

Yep...
The trimmer should have come with some hand drawn instruction pages on how to do the adjusting too.

The text of the instructions can be found at their website:
