The same push test to find oal and plunk tests for CZ barrels apply here regardless of the firearm model. I would use those parameters for the gun(s) you are loading for.
Exactly.Please review the notes on reloading in the Stickies once again.
• When data shown in the reloading manuals tells us the OAL was XYZ length what they are saying is, "This is what we used and the results we got." They are NOT saying this is the "perfect OAL", that their OAL will work in every gun, or that they think this is some kind of never-fail, always-feed-correctly dimension. Since every maker's barrel is different, how could one OAL fit all guns ? Far from it. By reading the manual you'll discover that ammo testing takes place in "test barrels". A test barrel is a huge block of steel bolted to a table top, with all sorts of meters and gauges attached. It is a "gun", but it is NOT a pistol, and it is most definitely not auto loading. It's a single-shot hunk of steel, such as pictured below...
In short, if an OAL is listed it is only part of their Lab Report. The OAL they chose works in their gun. You might be able to use that same OAL if
your gun
looks like their gun. Their gun looks like this....
But I highly suspect that your range gun does
not look like their test gun, so you'll need to sit down and do the "push test" to determine a useable OAL that will work in your gun. This OAL is a product of how
your bullet interfaces with
your barrel... and so the results are
unique (e.g. one-of a-kind, individual, discrete, distinct).
Thus, only you can derive the OAL for your bullet in your barrel.
Hope this helps.
