  • Trimming Cases :)

    I wuz trimming some 358W cases tonight and I tried to remember when I read a discussion on when and to what point does one trim?
    So here we go. The book says max or ideal case length of the 358W is 2.015.

    So, at what point do you chaps consider it stretched and needing trimmed? 2.016? More?
    And then when you do trim what do you shoot for, exactly 2.015 or less? How much less?
    For me it was 2.010...
    Let the fun begin!

    I think about hunting when I wake up in the morning. I think about it all day. And I think about it at night. The only time I don't think about it is when I'm doing it. ~credit to Carl Yastrzemski~

      Everyone has their own ideas on trimming, I don't think there are many wrong ways to go about it. I like to trim about .010" short of the call out or to the length of the shortest case in the batch. I don't worry a bunch what the exact number is, my goal is to get them all the same at some leangth that is at least .010" (.020" is what I like if I were looking for a number) off the end of the chamber.

        2.015 is the case length.

        Trim To, length is .010 less, ( 2.0050 )

        Get into trouble length is reportedly, .010 More than the published case length of 2.015.

        I check the length on Each and All cases after they are sized.

        I usta, just make sure they weren't longer than a gauge and trim if they were.

        Then, I got a Caliper, and measured them all, and trimmed to the shortest one, if it was in limits.

        NOW, I trim them ALL to the Trim Length.

        I perceive that many folks don't pay enough attention to cartridge length, and as a result fail to trim them properly, or at all.

        I trim cases with a Forster Case Trimer using the proper collet for the caliber.

        Recently, most times, I use the Lee Case Trimmer tools that are cartridge specific, because I don't have to adjust anything, I can use power, I can chamfer the neck, inside and out, and smooth the end, before I take it out of the case spinner.

        When trimming with power, even with the Forster, it needs to be done kinda slow like, or the ends will edge over on the outside, making them harder to chamfer, and smooth up.

        Like Andy says, they should ALL be the SAME length, especially if you are gonna crimp.

        IME, After firing and sizing again they WON'T all be the same length, some may be too long, so you gotta check'em, and trim'em and make them allee same, AGAIN.

        Do not neglect this important duty. OR, a calamity awaits you.

          For all my semi auto's I trim to the min case length. For many others I have simply set the trimer to something between max and min case length and leave them set. I use trim dies so there is no change in length. All sized cases are run through the trim die for consistency.

          Not trying to highjack the thread but...for what it is worth I recently purchased a very well made case trimmer from Little Crow. One of the best trimmers available? At least that is what they say. I am having trouble getting consistent trim lengths from case to case out of the trimmer. At 100 bucks for the model for different cases I can not recommend the tool.

            Wal, I dunno. I never tried one like that, BUT I have a thought, if it applies.

            Using the case trimmers, I've used and with POWER, it matters how fast and how violently I use it.

              I use a old Forrester I have had for many moons, works ok, but there is room for improvement as I can take too much off with a little too much effort...

                I suggest you try the LEE thingys, and be gentle.

                The Forster is only as accurate as how well the case head fits the Collett, and case lots can differ. I think the Lee is more accurate.

                  Gonna have one on way from Midway on Monday Smitty. I read a lot of reviews and they were very solid and I see I can get it set up for 358 which is great! I am going to get the insert for power drill use as well as the big round ball - looks like a very versatile tool setup. One more thing my kids will look at when I leave this world and go "wonder what pops used this thing for "!

                    Maybe it's just me but I just cut new brass to min the first time, then not worry about it until they reach max the 2nd time then it's about time to toss them anyway.

                      On the few rifle calibers I trim, I use mostly the Lee trimmers. I have a mini lathe that I chuck the pieces in which make trimming very fast. They all seem to trim a bit under minimum but I don't mind cause they are all the same and I don't have to retrim for a while.

                        I usually get around 5 loadings before I have to trim some, and then its only part of the batch.

                          Well, I heat treated about 35 rounds of 358 for the first time, interesting but I don't think it will replace Monday night football. I noticed that 2 cases when I trimmed them the neck caught on the Forrester trimmer and bent the neck to the point I pitched them.
                          So I assume that may have been too much heat and it made them brittle...
                          Trial and error are my best way to learn. Hopefully I can find some powder soon to reload these - geez!

                            Quite the opposite. The heat softens them. Flexing, as in firing, resizing, and especially enthusiastic crimping hardens them and makes them candidates for splits. The point of annealing is to soften them back up to avoid splits.

                              What BB said. Softer. It sounds like a dull cutter maybe, mashing the soft brass over till it mashes over enough that it binds up and twists the neck. Are you using the pan method to anneal? If you stand them in water to about 1/2" below the shoulder you just about can't overheat them with a plumbers torch cuz the water sucks off the extra heat. It's hard to mess up with the pan method and it's super easy.
