I bought a new CTS trimmer. I was receiving inconsistent trim lengths. I spoke to Jim at CTS and he was asking me about head spacing and if I used the head space gauge that came with the trimmer.
I had not used the head space gauge that came with the trimmer.
Jim gave me some instructions that included shooting a 5.56 and insert the case into his head space gauge to get the value for my rifle so I know what I should size the case to. According to him, the post sized case should be .006-.008 less than the size of the fired case. I discovered that my post sized cases were the same length as the case that I had fired.
This tells me that I was not properly sizing my cases right? This is probably why I had an issue extracting a couple of rounds from my AR.
Who all checks their head space so they know what the resizing die needs to be set to or do you just give your resizing die another 1/2 turn after meeting the shell plate?
I have not trimmed any of my newly sized brass to see if trimming is more consistent yet. I hope to do some trimming this week.
