| ok guys, this is my problem after resizing my brass I have a bunch that needs trimming. but my hornady # 15 trimmer pilot wont fit the brass. what have I done wrong on my set up. yes I am using the right trimmer pilot . help |

I have never needed to trim 9mm cases. Measure case length after sizing. Max length is .754. The few cases I have measured were at the .744 measurement. In the follow on posts, you will see very few people trim 9mm cases. Measure some sized cases and post the measurement.

In my opinion trimming any straight walled handgun case is a complete and total waste of time. Especially when you consider 9mm, .40 S&W and .45 ACP all headspace off the case mouth and are given a light taper crimp to secure the bullet. None have never grown to the trim lenght limit in my 30+ years of reloading.
PPC shooters and Bullseye have been known to trim .38 Special in an effort to create an identical crimp pressure for every loaded round. Only the top rank competitors will gain any noticeable advantage from this tedious process. |
| now I see whats wrong I load a lot of .223 an 308 ammo. new to loading 9mm just started today LOL. but the dies was free and I was sitting on about 600 hulls so why not try it. I have to trim almost every 223 an 308 hull. so to put in in a nut shell keep my specs between 0.749 to 0.754 and my glock will safe to shoot |

Yes.
Most of the time these rounds are not even really head spacing on the case mouth. Many are fired with just the extractor holding the case. Most designs lock up pretty much using the same principle though there are differences. This type of lock up must have a good bit of tolerance for ammo headspace. I say this because you rarely see if fact I've never seen any problem with ammo and the problem turned out to be case length related in a semi auto caliber like the 9mm. |

trimming brass is the most hated step in reloading (unless you have a Giraud) and the best thing about loading pistol besides being able to use carbide dies and not lubing
don't make loading pistol rounds take anymore steps, skip this step and have an enjoyable reloading session |
