All this talk about Knight BP's 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 flas 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?

I bought a pair of power stem breech plugs to try in my Elite about a month ago. I think I also saw Toby say it was a no go with BH209. My plan was to see if the combination FFFg T7 and the power stem in a .45 would out perform BH209. It may be another month before I can get to testing with it though. I still need to get a chronograph some day.

That is my problem also - TIME... but i will get to it eventually..

Not sure you are going to like 3f in a 45 cal.. the bullets we are shooting are so light that it really doesn't do much good with the heavy loads of T7-3f, 2f actually works better with lighter bullets...
