Kinetic hammer/Inertia bullet puller kaboom theories???

A vehicle's pressure on the road is its weight divided by the surface area of contact with the road, EXACTLY and this is pounds per square inch. If what you said were true, deflating the tires would reduce the pressure of the vehicle on the road to zero. Or, removing half the vehicle's weight without changing the tire pressure would leave the vehicle's pressure on the road unchanged. Both of these are clearly not true. When changing tire pressure or removing half the weight, the contact (surface) area between the tire and the road also changes.


My comments are in bold in your quote is my response.

Bullet Puller

I guess the most scientific way to answer this question is purely the "Experience Factor". As mentioned in one or two posts above: "I've been using 'the hammer' since approx. the '70's; unpacked thousands of cases over the years and never had one go off." Now, at the tender age of 70, the only damage I can predict is to my aging hands.......p.s. have even popped out 'live' primers from unloaded cases by sending them back up thru the sizing die with the primer de-capp'r pin and still nothing has gone off.
