Hello all. Long time lurker first time poster. (Honestly I tried posting this a couple of days ago, hence the testing area)
I have a long term project that is finally picking up some steam.
It is a Martini cadet action for those who are curious.
I've already aquired the donar rifle, dies, .22 Hornet brass and an extractor blank.
Next I'm in need of some information I haven't been able to find online. Mostly concerning twist rates, velocity and boolit stability. This will determine barrel specifics for this project.
After much reading I am looking for a Ideal 280412 HP mold, I'm hoping to launch these at subsonic and supersonic velocities and don't know what twist rate this would require.
Does anyone happen to know the max length of .277 straight wall, a cadet action will take without grinding the block? This will determine the OAL of the cartridge there by effecting volume which in turn includes/excludes various powders...
Any suggestions on where to repost this later? Single shots, projects,... Possibly break down the different questions into different posts for different sections?
Any and all input would be greatly appreciated. Thanks ahead of time. Jeff
