The Power Stem should increase the velocity using T7. Lehigh Dave suggested the frontal ignition system a long time ago as a way to increase velocity. I just do not like the thought that I can not clean the bore to the bottom with out removing the breech plug. But to the question I have never ran a power stem through a chrono - so I am also relying what i have read from others. Might be a good thing to do this spring.
That target you posted was sweet though. Nice rise comparison as the load went up and BAM smoking group with a heavy charge.
I just wish I could have run the comparison I had planned for this morning... time is really running out fast for me to do much experimenting as Elk season is just around the corner...
