The idea of a wildcat appeals to most of us but to be successful it should fill a need, or a space between cartridges.
One can wildcat any cartridge, but unless it does something needed, it is just a lot of expense and
trouble.
A wildcat can be any cartridge with any changes to the original design/specifications . Sometimes we just want something different and are willing to except the time and effort to go through with
the project.
Wildcats can be problematic and lots of though and study should be invested before starting
down this road. (Not trying to talk anyone out of doing a wildcat just warning that this should
not be taken lightly)
There are lots of variables that have to go into a wildcat for it to be successful and safe.
PO Ackley discovered that simply changing a cartridge did not always benefit it so he looked at improving it by making some simple changes that would improve brass life, aid powder burn consistency, lower bolt loading on the bolt and action, and increase powder capacity just enough
to improve performance.
I have designed several very successful wildcats that did exactly what I wanted them to, and found that most of the time velocity was not the main goal.
I would recommend that you start a list of your needs and wants and see if there is a cartridge that closely fits and see if it can be improved with minimum changes. sometimes major changes are a bad idea for some cartridges.
Go slow, and have fun with it.
Just my opinion and some advice from an old shooter.
