Now I'm Worried

    I'm worried because one of my reloads broke my Taurus 709. The details are:

    Loading 9MM with 5.3gr Unique, CCI and Federal primers, mixed brass, Rem JHP, Ranier, and Precision Delta bullets. All bullets 115gr. OAL at 1.14. New to reloading, I thought this would be a safe load. What I didn't know then but understand now is that different bullets of the same weight can make a difference in pressure. But still I don't think I'm that far out with this load to make a significant difference among these three bullets at the length I'm loading. (May be some argument here)

    Since the Taurus was new, I first fired 100 rounds of standard American Eagle target ammo - 115gr. I did this in two 50 round sessions followed by a through cleaning and re-oil. Then I loaded a clip of my Precision Delta reloads and within a few rounds the gun would misfire and fail to cycle. The misfires were soft strikes on the primer. I loaded these in my Beretta and they fired no problem. I tore the gun down and found the recoil spring broken.

    This load (with all three bullets) has been working fine in my Beretta 92FS (5 inch barrel) and my XD Subcompact (3 inch barrel). And I can't feel any difference in the recoil.

    So now I'm worried that my loads are too hot and its only a matter of time before I destroy or ruin my other guns, not to mention personal injury.

    What do you all out there say? Am I loading too hot or did I experience a random or infant mortality failure in the Taurus? By the way, the Taurus is a three inch barrel. Need some help here. I don't want blow myself up or even worse, the guy standing next to me at the range.

    I don't reload 9mm so FWIW. Your load is one full grain below Alliant's data and doesn't appear to be hot by my research. Maybe Taurus failure?

    Could just be a bad spring.

    A few years ago I had the outer spring (of 2 spring system) in a .40S&W Mini-FireStorm break while using factory loads. Granted, it was after a few hundred rounds had been fired but shows it can happen. (They replaced it for free with a single phone call.) A thousand rounds plus later, not a hitch.

    The 9mm headspaces on the case rim (like the 45acp) & if your brass is too short, you'll have issues like soft primer strikes. The next time you have a misfire, save it/them & measure the case length.

    Re; the broken mainspring - IMHO, you had two seperate problems @ the same time.... IOW - 1 didn't have anything to do w/ the other. I would think the breakage is teething problems w/a new firearm.

    Bummer.... :(

    Go ahead and measure a bunch of 9mm cases. Most all will be short, even the factory loads. Sounds like theres a need for lubrication, or theres a weak spring. The Berreta apparently has a sufficient spring to strike the primer, the Taurus apparently does not. The loads are not too hot (according to my manuals), so that should be of little concern. Another thing you might check though is to make sure your primers are seated all the way. If not, that first strike may not cause detonation, but will set it in a little deeper. I have made that mistake before. Oh yea: the 9mm and .45 do not headspace off the case rim, they headspace off the case MOUTH. I'm sure thats whats was meant, but it needed stated anyway.

    If you know you took your time with your reloads and a litmus test of two other firearms proved fine then a firearm failure (especially Taurus sorry to say) is quite evident to me. Your only choice here maybe to randomly pull the bullets on a few, if you have some left, and double check your work. I reload 9mm and your recipe is near exact what I use. Good luck!

    After the above posts, my thoughts run along the lines of a simple spring failure. I don't reload 9mm, cause I don't own any guns in that caliber, but if your load is within the specs of the reloading manual, then ya gotta look to the vehicle that launches them.

    Different bullets of the same weight don't alter the pressure, different OAL and powder charges may be required from different bullet shapes and that can the pressure greatly.

    As others have posted, you need to follow the load data for each bullet/weight/powder to insure safe reloads.

    I agree that the spring beaking may simply be a coincidence?

    Thanks everybody. I appreciate the input. I went back and checked my loads and primer installations and everything is loaded to spec. And I rechecked load data that I could find and I should be well within a safe range on the powder load. The only thing is that I could not find load data on the specific bullets I a using except the Rainer people say to load as if it is a lead bullet.

    Any way, with you all's help, I feel better about my loads and when I get the new Taurus spring I will try it again - very carefully!

    Oh yeah.... Not gonna drag this out but I caught an accident such as this before it happened a year or so ago. I bought a few thousand 165 grain lead head bullets from an online store. I am very perticular when it comes to my know, measure, measure, measure. Well, I opened up a box of the bullets and started randomly weighing them on my digital scales and W O W!!! I had bullets weighing everywhere from 145 grains- 195 grains!!! I flipped completely out. Remember now, these were supposed to be 165 grain bullets. I contacted the company and informed them of this issue and they told me that my scales must have been broken...LOLOL Afterwards, I took a few pictures of the bullets on the scales, posted them on a different forum such as this one only to be pounded by people on my thread...unbelievable right? This happened! The people started bashing me stating that my scales must be broken...LOL Come to find out, the instigators were the very people that owned the company where I had bought the bullets!! I would guess to say that they called everyone possible to help them discredit my claims.

    When loading any ammo, especially small pistol ammo, the powder loads need to be perfect if you are loading to max, well, thats my opinion anyway. So maybe this is what happened to you on this occasion. Just say I loaded a max powder load for a 165 grain bullet and in actuality, the bullet weighed 190+ grains...Just a thought...
