Is this something I should be concerned with?

    As you know, I am very new to reloading and am still quite nervous. The image below shows a split case on a 9mm that I had reloaded.

    The once fired Federal case was loaded with 147 grain RMR cprn with 3.4 grains of Unique and CCI primer with a COL of 1.135. Of the 100 I fired, there is only 1 example of this. Could this be a fluke, or am I expanding the case mouth too little/much, or odd piece of brass? Or something else? Hopefully not serious as I have 300 more of these loaded for Friday night. Thanks in advance.

    In my opinion, that split has nothing to do with the amount of flare you put on the mouth. I would venture to say that that particular "once fired" case has been fired multiple times for it to split like that. Especially if it was the only one out of a hundred.

    Agreed, looks like a burn thru fissure, not a mouth split

    Thank you. I generally have only shot factory loads to this point and always police my brass, perhaps I picked up a leftover from someone else.

    It's either a fluke or you picked up a piece of odd brass. I wouldn't get overly stressed about it.
    Curious though, where did you get the load data?

    I've had the same thing happen in my wife's 9mm, and my 45 when using brass that has been reloaded multiple times. Just wears out.

    Thanks again, I'll keep an eye on it Friday.

    From friends, I started a 3.9 and worked my way down. These are for plinking and reducing recoil so my wife will go more often. All will run at 3.1 except the Kimber Solo, 3.4 works in our 9mm's.

    You seem to be going at it backwards, you don't start at a number and work down, you start at the minimum and work up.

    The only manual that I have that has the combination of Unique and 147 grain projectile has the MINIMUM load at 3.7 of Unique!

    To the OP, I suggest you re-read the reloading portion of your reloading manual before you load more. You are not going at this the correct way, and some powders do not react well to loading under minimums.

    Good info right there. A below minimum load in some combinations can be just as bad as an overcharged load
    And a friends "pet load" is not the place to start either. There are other ways of reducing felt recoil.

    1 out 100 isn't an indication of poor reloading but of one bad case.

    "From friends, I started a 3.9 and worked my way down. These are for plinking and reducing recoil so my wife will go more often. All will run at 3.1 except the Kimber Solo, 3.4 works in our 9mm's.
    "

    One of the quickest ways to ruin a gun or lose some fingers is to get load data "from friends". While it may work 98% of the time, you, as a new reloader are betting a lot on your friend's load data. I prefer to get my data from my manuals even though your friends are well intentioned. Reloading "backwards" isn't a normal "good reloading method" either. Start at the starting load and work up. If our wife experiences too much recoil from minimum loads, perhaps a heavier gun or smaller caliber. Going outside the listed powder charges should be a method only used by more experienced reloaders that can determine if a load is detrimental to the gun/shooter...

    I've been reloading for prolly 30 years (I started pre web) and I do not pay much (no) attention to any forum expert, range rat, pet loads website, gun counter clerk, well intended friends, or gunshop gurus. I get all my load data from published reloading manuals or powder manufacturer's web sites (only about 5% though). This has worked well for me and I'v not had any KABOOMS. I had a squib in 1970 but that was my fault and I now look into every case befor I seat a bullet...
