I reload .45ACP.
My two loads are:
1) 5.3gr HP38 under 230gr FMJ Fed 150 primer
2) 8.5gr AA#5 under 230gr FMJ Fed 150 primer
Both loads are well under SAAMI spec for the .45ACP according to published data.
I shoot load 1 out of my Sig and load 2 out of my S&W 1911.
When shooting load 1 out of the Sig I often find a small secondary dimple in the primer that intersects the firing pin dimple. In other words it kinda seems like the pin is hitting the primer twice. When shooting load 1 out of the 1911 no such double hit is happening.
Question: I shoot Hornady .45ACP +P 230gr XTP's out of the Sig and don't get the apparent double strike. Is this a double strike in the Sig resulting from high pressure or is something else going on?
I'm betting on something else since the load works fine in the 1911 and a +P load works fine in the Sig.
What could be happening here?
