I have yet to notice a post here or elsewhere that a heavier or lighter hammer had any noticable improvement in the performance of the marker on the field of play. I have heard more negatives than positives 10 to 1. They seem to have been 'fashionable' at one point and has since fallen by the wayside because of the 'no noticable improvement' by those that tried it. The general trend was to use a heavier hammer with the theory being that the mass/inertia heavier hammer would increase the duration of the valve being held open. Thus one could potentially lower the operating pressure of the marker a little more to reap the benefits of Low Pressure. Well, the difference in 'performance' between 275 psi and 225 psi operating pressures is NOT observable but possibly measurable. The RATE that the valve is opened is also a factor of the inertia (mass x velocity) of the hammer. A heavier hammer with the SAME spring pressure would open the valve SLOWER because the hammer is moving slower. A slower opening valve offsets the benefits of a longer opening valve. To get the valve to open at the same RATE, one would have to increase the spring pressure via velocity screw or heavier hammer spring. Now a heavier hammer spring requires more recocking pressure in the pneumatics to overcome the resistance of the heavier hammer spring during recocking. Thus would increase the likely hood of a chop on bolt closure. A negative. A heavier hammer spring also results in a heavier trigger pull. A negative. But in reality, there is likely a happy medium relationship of the hammer spring, and hammer weight that is ideal.. Do you suppose the people that engineered and tested the autococker's development have ALREADY figured that out? That's my bet... Confused Yet? So is everyone else..... So if you want to GO THERE, Try This. The cocking rod is PART of the hammer mass. The cocking rod NUT is also part of the hammer mass. You could increase the total MASS of the stock hammer/cocking rod/nut assembly by simply replacing the cocking nut with a 1/4 - 1 oz piece of 1/2 diameter brass rod drilled and tapped just like the cocking nut. Add a spring set and go tinker. Scientifically test your results and post it here. Inquiring minds want to know.......
