Re: Question Regarding Redding Bullet Seating w/o Crimp
Greetings Brown Dog,
I truly beleive your worries are unfounded.
I have a RCBS Rock Chukar Press. It has a cam like stroke. If you pull the handle up, the ram goes up. If you go past the ram full up position, the ram come down a little (put a line with marker on the ram shaft at full up position and see if it goes down a little when the handle goes past center).
My point is that the presses stroke has the same effect as the cam in your vehicle motor that lifts up your valves.
Now the valves in your vehicle motor have springs that exert pressure on your valves which keep the valve stem in constant contact with the cam.
In your loading press the "spring force" is actually the resistance of your brass being deformed as the bullet is pressed in. You would have to be pulling your handle faster then a mortal man would be cabable of to create enough speed induced momentum to force that piece of brass to leave the surface of your rams base.
So in conclusion, with the resistance of bullet insertion, your brass base will never be able to jump up and away from your rams base.
As a matter of fact, if you did make your press hit a solid metal to metal stop, you will, more than likely only cause premature wear on the bearing surfaces of your press.
