So if this is true, then what happens when you have two loads at the same powder factor with the SAME bullet weight, but one using 3.7 grains of powder A and one using 4.3 grains of powder B? The 3.7 grains is a max load at 32,500 CUP and the 4.3 grain load is a starting load at 28,900 CUP? Will the 4.3 grain load recoil more even though less pressure is generated?
So you are really going to make me think at 6pm after I just got back from work! Ooof.
I may be wrong but 2 different powders cause variables. But, to me, pressure is a spike in expanding gas.
Powder A may be fast burning and spike with the bullet only 1/2 way down the barrel.
Powder B may be slower with highest pressure as the bullet exits the barrel.
With fast powder A, pressure would decrease as the bullet exits the barrel.
With slower powder B, the preassure would be more steady causing more felt recoil since powder burns slower expanding the gas at a more steady pace.
If I imagine a bell curve with the 2 powders, powder B would have a longer, more steady decrease vs. the sharp up and down of Powder A.
OK - thats enough. My beain hurts. Bourbon Time.
