Hey guys,
Loading 9mm here and been at it for about 6 to 8 months now. I have been loading on a single stage redding and seem to be producing fairly good ammo.
My question has to do with case length and getting proper bell and/or crimp. I am mostly reloading 9mm. Manual shows trim to length of .744 and max length of .754. Now I know everyone says they don't trim pistol brass but how can you get consistent ammo if you don't?
My current routine involves measuring clean, resized 9mm brass into two buckets. One bucket holds 9mm brass that is .744 to .749 and the second bucket gets brass that is .750 to .754. Most of the brass measures in the .750 to .754 range so I have setup my dies and been loading it. The cases that fall in the shorter part of the spectrum are collecting dust at the moment.
If I were to take a short case, say .744 and attempt to reload it I run into problems. Based on die setup it won't get enough bell to set the bullet on top. I feel like if I change my the setup of my dies to be ideal for cases in the lower spectrum then I will have the reverse problem. Longer cases would be belled too much.
But everyone says they don't trim pistol brass. Literally every single progressive press youtube video the guy says he just throws everything in there and goes to town. Same with the threads on reloading sites. How do you avoid the consistency problem with brass can vary from .744 to .754? Do you setup your dies to bell the shorter cases the right amount and live with the overbelling on the longer cases? Sames goes for crimp right? If you setup dies to for best crimp on shorter cases then longer ones get too much?
