A 155 gr .40 caliber Gold Dot @ 1200 fps and a 200 gr .40 caliber Gold Dot @ 1050 fps have nearly identical energy, but one is for sure going to...
Force is mass times acceleration. Force is also one of only two variables in impulse. You literally can not separate acceleration from impulse....
Energy is not what deforms bullets. Velocity deforms bullets. This is why loading manuals list expansion velocity thresholds, not energy...
No, you are wrong. That is why impulse is expressed as force over time, because time is half of impulse. You can't discuss impulse and ignore the...
Just an opinion, but in my area, the 10mm has already overtook the .357 Magnum...
You're wrong. Impulse is the amount of time it takes for a force to act on a system. A shorter impulse time is a more violent reaction. Time is...
Bullet expansion is a product of velocity, not energy. A bullet has energy as mass and velocity. The only way the bullet does work, or loses...
Or if you would rather hear it from someone who designs and tests bullets rather than someone who builds $6000 rifles, here's some guys from...
The 240 gr JHP @ 1300 fps will expand faster and to a greater diameter, increasing permanent wound channel size, and provide momentum for...
Energy is irrelevant with handguns, because they don't have the velocity to use it. So power with handguns is determined by size of permanent...
They have nearly identical SDs but the 200 gr 10mm has the advantage in momentum. Why would you think it would penetrate less when driven to...
The 200 gr XTP @ 1250 fps is being driven much closer to its manufacture recommend max velocity than the 158 gr XTP @ 1150. The 158 gr XTP is...
The .277s had fallen by the wayside, but has seen a revival of late. SIG introduced the .277 Fury with a fast twist barrel. Nosler has introduced...
The M1 Garand is not a cheap rifle, and never has been. It requires a deferentially heat treated receiver. The recess for the left locking lug is...
It is actually a function of bullet length, not weight. But as diameter is fixed, heavier bullets of the same caliber are generally longer. Still,...
