To the question: Why this poppet - but could be done with poppet valve as well. Because quote doesn't seen to work???
This rammer can't be used in a true Poppet, balanced or not.
I tried many differ ways to get the Rammer lighter and get a smoother shot. About an ounce and a quarter is as low as we got it without raising the pressure and then at an ounce it started to be very counter productive. This Rammer, or because of it's weight we are calling it an actuator, is 0.2 ounces. We also lowered the weigh of the bolt. Overall we reduced the moving mass 55%. Pretty impressive, I think, especially in a double stacked design - made by a lot of manufactures for many years - when they all weight about the same.
The original motive was to reduce the sound signature and reduce the weight of moving mass and it was more successful than hoped for. It is a Spool sound signature - and the lighter weight.
The cool thing about the sound is that although the sound isn't half as loud, your ear perceives it as half. The human ear is very sensitive to changes in sound. The snapping branch can be lower in decibels, but heard better than a sound that raises slowly. Or in this case, the opening of a poppet is located more easily vs. the opening of a spool.
