What you are saying is that men who do not like ugly recoil pads are faggots.
I think a man who cannot withstand the recoil of a 7 mag without a gorilla-sized recoil pad is a wimp.
No, not exactly.
My father derived the formula of a parabolic taper hydraulic cylinder for constant force over constant recoil distance, regardless of load. He did that in the 1950s when he designed the M55.
I have not done any super important things like his patents, but I have figured out a couple things:
1) The threshold of recoil pain in a rifle I have given some thought:
Given:
The rifle weighs 10 pounds.
The bullet weighs 250 gr
The powder weighs 75 gr.
The muzzle velocity is 2500 fps
The gas velocity = 1.5 projectile velocity
The untrimmed large recoil pad is 9 sq inches
The recoil pad stiffness is 100 pounds/ 0.2"
The loss of Navcom material in Limbsaver recoil pad 75%
The threshold of pain is ~10 kg/cm2
Goal:
Calculate if it will hurt.
Calculation:
projectile momentum = mv = [[250 gr] / gravity ]][2500 fps] = 250 gr / 7000 gr/lb / 32.2 ft/sec2 [ 2500 fps] = 2.77 slug ft/sec
gas velocity = 1.5 projectile velocity = 1.5 2500 fps = 3750 fps
gas momentum = 75 gr / gravity 3750 fps = 1.25 slug ft/sec
Total forward momentum = bullet mv + gas mv = 2.77 + 1.25 = 4.02 slug ft /sec
rifle momentum = bullet + gas momentum = 4.02 slug ft /sec
rifle velocity = rifle momentum/ rifle mass = 4.02 / 10 pounds/ gravity = 4.02 / [10 / 32.2] = 12.9 fps
Rifle energy = [1/2] [m] [v][ v] = [.5] [[10] / [gravity]] [12.9] [12.9] = .5 [10 /32.2] 12.9 12.9 = 26 foot pounds
Energy not absorbed by recoil pad = rifle energy [1 - pad loss] = 26 fp [ 1 - 75%] = 6.5 foot pounds
The recoil pad stiffness is 100 pounds/ 0.2" = 100 lb / 0.0166 ft = 783 lb /.13 ft =
783 pounds compressed, 0 pounds relaxed, averages 391 pounds.
[391 pounds] [.13 ft] = 6.5 foot pounds
783 lb peak force / 9 sq in = 87 psi
The threshold of pain is ~10 kg/cm2 = 142 psi
87 psi peak pressure of recoil pad on skin / 142 psi threshold of pain = 62% of the threshold of pain
Will it half hurt?
No, because the whole shoulder moves, while 783 pounds of force may have been available to a brass statue shoulder, it was not realized. Only part of the energy goes into the recoil pad, unless the shooter is backed up against a tree.
2) I am not saying that men interested in aesthetics with feminine voices are homos.
I have observed that while speaking to people in the dark while walking the dog, I can make prediction:
a) most masculine... male conservatives
b) less masculine.... male liberals.
c) even less masculine.... male homosexuals
d) least possible masculine.... women's voices recorded and played back at half speed are an octave lower than original.
