Ok so here it goes.
Couple of things I forgot to mention. All of my test guns are P.O.F. Rifles which are piston guns.
My 18" gun has a mid length gas system
My 16" gun has a carbine length system
And the 14.5" I'm testing has a mid length gas system
And I had a buddy out there with a jp 18" setup
We shot all of them side by side at short range. The 18" barrel jp shot the softest but only marginally better than the 14.5" Pof
The 14.5" surprised everyone that shot it including myself. It was really flat shooting. but the softness and flatness of a gun is kind of hard to measure. But splits and transitions were a little faster with the 14.5 but not really a big difference in the grand scheme of things. We're talking .01's
We chronoed them and as expected I lost velocity with the 14.5" but not as much as I thought. There was only about a 100 fps difference between the 18" and the 14.5" with the 16" almost exactly in the middle.
I'm going to shoot it some more at the local 3gun match this weekend. If anyone wants to give it a try and tell me what they think I will be at rio salado on Saturday for the 3 gun match
Thanks for the input,
