    Case trimming

    I'm just wondering how often people trim their cases and at what point do you trim them? After every firing or every three?

    i have a few hundred .223 and some of them are on their 4th loading, I sat and resized them tonight and then inserted and measured them and the majority are at 1.736" but I have a few that are at 1.755" so approaching the max length of 1.760"

    i dont usually trim them after every fire as long as the case length is consistant but just wondering what others do?

    regards,

    I trim each case to the length of the shortest case in the bunch, at each firing. I crimp, therefore I trim. Consistency is the #1 rule in reloading.~Muir

    I trim every time to keep things as consistent as possible.

    As said above, for consistency every time I resize I trim.

    +1 for every time. Keeps things consistent.

    I have a reference trim length for each cartridge I shoot. I measure the cases and if they exceed the reference length they get trimmed and de-burred. If they don't exceed the ref trim length I do nothing.

    After sizing I length check all cases & trim each batch to consistent length below maximum removing minimum metal possible. All get checked for chamfer inside & out & all cases have the mouth polished with Scotchbrite to remove the smallest burrs.
    The polished surface reduces the likelyhood of crack propagation.

    After cleaning, de priming & sizing I always put my cases on the trimmer. Sometimes some comes off, sometimes it doesn't but the end result is they are all the same length.
