@Paul120 Indeed you cannot change the laws of physics. Jim or even Issac Newton.
So... what laws of physics are at play in the process of breaking a clay?
In simplistic terms, the clay will break when sufficient force is applied to it to cause it fracture.
So, keeping it to actual shooting, we can say that the force applied to the clay is from the transfer of kinetic energy from the shot to the clay (material is irrelevant at this point).
We know that Force equals mass multiplied by acceleration plus work done against friction (Deceleration is negative acceleration)
So at the point of impact, the velocity of the pellet mass is decelerated by the clay and this a force is applied to the clay.
The laws of physics say that every action has an equal and opposite reaction. Thus the pellet is also subject to the same force as the clay and is this also subject to some deformation.
now here is where material properties begin to plug into the physics equation. Change in material density will mean that pellet volume (diameter) will change accordingly for a given pellet mass.
pellet hardness also comes into this too. This is why we add antimony, or tin to lead, or in part, why we add coatings, though the coatings have a different primary functions.
a harder shot transfers more kinetic energy to the clay. With softer shot, some of that energy is used up in deforming the pellet itself and thus there is less energy available to transfer to the clay.
in summary, given basic laws of physics, a steel pellet of the same mass as a lead pellet would in free space transfer more energy to the clay.
a steel pellet of the same diameter as that if a lead pellet has less mass and thus less energy to begin with
bringing to the equation more complex physics does complicate the issue, but these issues are the same regardless of material. The material simply modifies the result , not the process or the physics.
these complications can be found in the work done against friction, the interactions between pellets whilst in the forcing cone, barrel, choke and interaction with the environmental conditions (air)
steel again exhibits properties that are advantageous over softer shot, but gives up in other areas.
to encapsulate that, steel shot cartridges would benefit from further optimisation in wad design, forcing cone and choke design.
this should be quite easily accomplished
@schmokinn only shoot clays, since May, less than 2000 shells, only 25 of those steel to date and those 25, not specifically optimised for clays.
My premise is that joe public are opposed to lead in any context.
of course we can offer up evidence to show that their risk is negligible. Heck, we may even be able to offer up evidence to show that the risk is nonexistent... from any source. But can we expect Joe Public to believe shooting minority who has lead use in its self interest or the scientific and health community With public interest at their core, whom many put their trust and faith in and have mainstream media on their side.
on the other hand, we can, sooner by choice or later by inevitable enforcement work towards adopting alternative materials, steel and optimising that in order to continue enjoying the sport.
change is a fact of life and has been for hundreds, neigh, thousands of years. Millions even.
the March of change can hardly be slowed, let alone be halted.
its perfectly normal that some will embrace change and others will resist, and whatever your preference that’s just fine. but history has shown change marches on unabated.
personally I tend to embrace change... though not always.
im not here trying to change anyone’s mind and I’m not here to have anyone change my mind.
I’m simply declaring my point of view as others do and I respect that, regardless of my agreeing or not
I may be a snowflake according to you, but this snowflake doesn’t simply melt under the heat of debate. I am all growed up and a big boy now and can hold my nerve against opposition. Especially when it’s something as trivial as this topic. I have and will continue to have much larger and scarier fish to fry.
im frankly a bit disappointed in how my comments have been challenged By and large. I’d hoped for reason, evidence, logic. I’m left wanting.
@Will Hewland Didn’t say much, but I felt what he had to say was thoughtful, thought provoking, intelligent and added value. Dare I say it, I’ll raise my glass to that
