Been a little chatter on another forum about Knight BP's and it has sparked an interest...

The Power Stem... Has anyone shot this BP?

I am really wondering about 'blow-back'...

Here is what i might be talking about... One of the reasons that the new BP works so well in the Vision is that it has a 11/64ths flash channel a little bigger than the normal 1/8 or 8/64th. It appears that this larger and slighly longer flash channel swallows up the blow back more effectively than the small cavity - this extra bit gives the bullet a chance to get out of the barrel which then completely reduces blow back to zero.

Just a few minutes ago - I was looking for the correct bit size to ream the flash channel in a FPJ BP. I have a Power Stem BP laying here on the counter - when I dropped the bit in the flash channel it swallowed most of the length of the bit. It would make a lot bigger blowback chamber - so it might result in a lot less blowback...

I know the Power Stem works well with T7 even increases velocity significantly. I think Toby declared it a non-worker for BH, but it really has peaked my couriosity.

So again anybody with experiance outthere with the Power Stem?
