I've been reloading 9mm, among others for a while now with no issues. I started with speer bullets, went on to 1000 Montana Gold in 124g HPs. I am now trying Berry's 124 hps. The Berry's are .020 shorter than the MG, but the straight portion of the berry's bullet is considerably longer then the MG bullet, .050-.070?. This is causing a problem in Wifey's Kimber Pro Aegis II 9mm, the bullet is hitting into the riflings and not alowing the slide to close fully. Even the Montana Gold bullets are stopping jusst slightly before, but the slide will close, and the gun fires normaly, I DO understand this is still not good and will NOT use the MG reloads in the Kimber either. These reloads do fine in my SR9c.
I put an MG reload back into the press to see how far in I needed to seat the bullet to get that nice "THUNK" sound when dropping the ammo into the Kimber barrel. It was about .025-.030, "THUNK", the bullet was not hitting the riflings.
My concern is pressure, seating the (MG) bullet .025 deeper than recomended in the book may not be an issue. Seating the Berry's bullet an extra .050-.070 MAY be an issue? I believe I will end up selling the other 450 Berry's anyway and getting another K of Montana Gold.
I'm currently using Titegroup at 4grns, but I'm wanting to switch to W231, which I think is also 4grns, and meters better for me.
Talk pressure to me GURUS, please.
Mike
