Not to burst your bubble, but you cannot get an orange out of an apple, no matter how hard you squeeze.
The laws of physics are not just really good ideas, and numbers do not lie, but you can lie with numbers.
Since I failed mind reading 1-0-1, and I took it twice, let me begin with what is the diameter of the transfer port, its shape and length?
There are two parameters that need to be addressed in order to understand the limitations and the efficiencies at hand.
If your transfer port is over 0.257 x 0.7071 = 0.182" then you will be on the road to higher power, less accuracy and more velocity deviations with a smaller shot count.
If your transfer port is below said 0.182" then you are on the road for less power, but better accuracy, smaller velocity standard deviation and higher shot count.
The reason for said dimension is because it is the half power point, or 3 dB down. What happens at the transfer port orifice is that great turbulent forces occur and cause havoc thus disturbing any consistency, which equates to precision inside the gun, and accuracy down range at the target.
What good is it to shoot a rabbit with an elephant gun? Especially if you are going to miss. Tyler had a great analogy on the carnival strong man sledge hammer bell ringing tower. Just hit the bell. You don't have to knock it out into outer space.
Get and post the size of your transfer port orifice, the shape if out of round, the edge if sharp or round, and the length because what follows is a phenomenon called the Vena-Cava, which when both optimized for efficiency and precision (not accuracy that's at the target, no gun is accurate unless you throw the rifle at the target and hit it in the bullseye).
Next, post your hammer spring dimensions such as the spring K-value, free length, compressed length, number of coils, O.D., I.D. wire diameter.
Lastly, the bottle pressure regulated at center of adjustment.
Else, face away from the wind or you will get your feet wet.
Go for accuracy first, and that comes from a precision and consistent gun and ammo. The shooters ability; well, not so much because you can always mount the rifle on a vise.
You can easily get 500 fpe out of your gun, but you would need to drop it from a high building, but by then the rabbit would have moved out of the way.
After accuracy, shoot for the least standard of deviation in the longest shot string.
Then go for power, but by increasing the mass of the projectile, and not the velocity, or you throw all your previous gains away then you start not at the beginning, but at the wrong end.
If anyone has the dimensions needed, please post and I'll explain with minimal algebraic gymnastics.
Last, but not least. Post your beginning pressure, shot count, and end pressure. Also include the bottle volume for those stepping in halfway in the blog.
I'll end with the following food for thought:
It takes approximately 8 air molecule masses to equate to one lead (Pb) molecule, so if both are allowed to share the same amount of momentum with an infinitely long barrel they would both come out with the same kinetic energy, and that is the theoretical highest energy possible of a lead pellet, or slug.
To get more energy from the projectile, just add more air. There is a limit on the air molecule velocity that is solely based on temperature at the kelvin range, but there is no limit on the cork, or pellet, or slug that is holding the compressed air molecules.
The more air molecules you add, keeping the temperature constant, the more pressure you will have, but the root mean square of the air molecule velocity will be the same; in other words, some air molecules will be at a complete stop, while others will be at super hyper velocities, but when you add the square velocity of each one and you square root that value, you get the mean square velocity. The average velocity is a little higher, but there are less air molecules travelling at that velocity. The peak velocity is even higher, but even less air molecules are travelling at the peak velocity.
Get me the values, and by then I'll figure out how to paste graphs on this blog so more can understand what is not said or mentioned in the myriad of blogs, air gun reviews and especially by the manufacturers and dealers.
The majority of my answers to questions on air gun reviews are moderated, examined and not posted. Could it be true that I was so happy when I was stupid?
I've learned a lot from the Blue Cookie Monster and Lloyds spreadsheets and videos along with so many other well review folks that I can't name at the present time because I'm beyond my time to go to bed.
FJB Out!
