    I know the minimum length is 1.760 but what is the maximum length you can trim a 223REM case?

    SAAMI MAX case length is 1.760".

    You can trim it any length you want as long as it is shorter then that.

    The suggested trim-too length is 1.750".

    BTW: Don't you have a reloading manual?

    As helpful as this forum is (and you received responses from two of the best), there is NO substitute for reading & understanding one or three loading manuals.
    After doing that, those two & others will be able to help far more!

    The recomended method is to measure and find shortest case. Then trim all to that length, this standerizes the case length for the same case crimp on every case. This is usually only required once for each batch of brass for several loadings as after that the same length fired in same chamber is pretty consistant in length, not necessarially the original trim length, but easilly adjusted for with crimp die with good results.

    I wouldn't. If it is at 1.746, it will stretch to 1.75 within a firing and sizing or 2 if it isn't split and worn out by then.

    I bought a bunch of once fired FC cases. I have resized them and they are around 1.746 to 1.751 so i trimmed them all to 1.746. They will be fine.
