40 S&W reloads
Thank you very much for your response. I didn't mention the pistol i'll be firing my reloads in, it's a CZ 75b. My oal is 1.120. My Lyman 3rd edition shows 2 loads for 175 grain cast lead using HS-6:
1. 7.0 - 8.2 175gr #2 alloy 1.125 oal, mould #401043
2. 7.0 - 8.4 175gr #2 alloy 1.100 oal, mould #401638
What mould was used for my 180s, I don't know.
Based on that info I didn't think I would be in any trouble using 7.7 grns.
Thank again,
Gordon
