Just curious if you know what your chrono strings are looking like, and what I should be expecting on my P-68 SC. How should my efficiency be? It has the original length barrel, enlarged bolt head, stock spring (I presume), and a lightened hammer.
First shots for me are quite powerful, then once I'm around 20, it feels like ~240-250 fps, but I haven't had a chance to use a chronograph yet.
I'm curious as to what the "norm" is, because I don't really know what to expect for this is my first stock gun. I hear phantoms and such getting +30 usable shots. Are they considering "usable" as 200 fps?
Also, my indoor field has a velocity limit of 250. Where can I find a lighter spring so I get better efficiency?
