AEA Early model AEA standard .357 big bore mod,s ???

[Fly]

I bought a AEA 357 standard big bore when they first came out. Love the rifle, but as always they keep up grading power ect.
It is a powerful rifle, but not as the new ones. What up grades can I do to increase the fpe in this early model?

Shim the hammer spring and test with fill pressures to find the bell curve. One can make a hammer spring adjuster also, I have the details on another form.
