I space mine in the middle of the top band but those look ok if they function.
Well, I took this round that I had seated to the middle of the top "rib" and seated it down to the top edge of that same "rib". It reduced the OAL to .933. I found that for some reason this caused the base of the casing to swell slightly. It would only fit halfway into the case gauge, but passed the barrel "plop" test. So for now. I'll load up a few at the original OAL and test fire them.
Steve, I think if it were me, I would load them as long as possible (assuming they function in your gun) and just be aware they may not function in a new gun you might acquire along the way. Just me though.
As always, OAL is bullet & gun specific, regardless of data. Load em long, see if they work.
I shot them at the range today in my CZ83. They all worked properly and I couldn't tell any difference in the accuracy. I used 3.0 grains of N320, clean burning, and nice recoil, so I'll stick with the longer OAL (now .970)!
If you end up getting a Kahr CM380/P380, you will likely have to load them back down to sub-.950"
I checked them out in a Bersa Thunder, a Beretta 84, and the CZ 83. I was fortunate that they passed the drop test in each of them.
Cool (and good to know too!).
Almost forgot, on the P380, it might pass the plunk test, but not feed the ramp. Length is a problem for most bullet profiles in those guns. It really is a ***** when you hand cycle and get a jam and then can't clear the jammed round as the slide won't cycle far enough back for the round length...
Thanks for the reminder, I'll check out the other two just to make sure.
They will likely be fine. The P380 is so OAL sensitive because it so small. Hella short action.
