I have a problem and could use some help.
Background: I am finished loading 600 rounds of .380 using once fired brass with a Remington 88gr FMJ. The charge was 3.4gr of Win 231 with an OAL of 0.971
Method: Decapped and resized each brass case. All of these cases freely went into the case gauge pictured below and freely fell out. The case was belled just a little bit and powder charge done. Bullet was seated to a depth of 0.971, and a crimp applied just enough to allow the finished bullet to slip into the case gauge.
All loading was done on a Dillon 550b using Dillon Carbide dies. Charges were verified with a Lymann digital scale.
Problem: After loading all the rounds I did my final inspection for cracks and such as I case gauged them. 40%
of the finished bullets did NOT fall into the case completely as shown below:
The gun these were loaded for is a Sig Sauer p230. Below is a picture of a factory round, Corbon DPX. It slips in and out freely. Below that picture is one of the rounds I made, it slips in and out of the chamber freely, but not the case gauge.
Corbon DPX :
88gr Remington loaded by me:
Question: Are these rounds safe to fire? They fit nicely into the chamber yet they fail to fit all the way into the case gauge. Can I determine if they are safe for firing by loading up magazines and cycling the rounds into the chamber? Any explanation why they fit the chamber but not the gauge?
I chronographed some of the rounds that case gauged all the way and my load is moderate at 881 FPS and no difficulties to extract.
Many Thanks !!
