Hi,
I have a 10mm load that I have used in my Delta with no pressure signs. It's a relitively lite load.
OK so here is the problem.
I have a Open bolt UZI. It fires Federal red box but blows the primers out. Wierd because I seem to remember that Federal is a lite load.
When I use my Reloads with new bress I get case seperations. Scary!!
The same batch of my loads rounds in my Delta are fine. No pressure signs/ no case seperations infact they seem lite.
The Federal I sent back to Federal and they said that they were fine and at about 1050 fps. (well within spec)
The guy that did the bolt and barrel says that they are both in spec and run fine in his with UMC 10mm.
I haven't been able to get UMC 10mm locally.
What would cause these issues?
Any help or guidence would be appreciated.
Thank You,
Pinkerton OUT!
