[ARCHIVED THREAD] - seating die issue

Posted: 1/28/2009 11:56:30 AM EDT

I am having trouble with one of my seating dies. I am getting very inconsistent COAL's. As in differences of two to three hundreths. It is my 6.8 dies that are doing it. I may get 2.290, then correct it to 2.30, and on the next round I will get 2.310. I am doing this for every cartridge. I am using Barnes bullets, so its not inconsistency in the bullets.

Thanks for the help.

That's 0.020 inches extreme. I'll bet it's the bullets, or a compressed charge that is pushing the bullets back out of the case.

The charge is slightly compressed at this load, but I wouldnt think it would be enought to push the bullet. I guess it could be that its pushing it out enough that I have to continue to adjust the die, but shouldnt I still be more consistent? I guess I dont understand the 2.290 length on the very next cartridge. Wouldnt the same charge push back with near equal force on every cartridge?

I should hope its not the bullets. When one pays $36 a box, they had better be very consistent. I am using TTSX's.

Thanks

The neck tension varies a little from case to case.

Load several by pushing them into the seater die twice, check the length, then let them sit for a few minutes and meaure the length again. Don't be surprised if a few are longer.

Run a couple dummies without powder and see what happens. You can always pull the bullets and load them again.

My guess is its the bullets.

I will try both of these troubleshooting ideas.

Thanks
