Ammo Pressure Questions

[roger-ruger]

I dont understand, when I checked SAAMI's pressure data I read that standard load 9mm and .40 S&W have the same pressure specs at 35,000PSI. Now im wondering, why a lot of people say that the .40 has a snappier recoil. Could it be its just another .40 bashing?

Enlighten me, thanks.

You're launching a heavier bullet with a heavier powder charge in the 40, that's what gives the extra pop to the recoil.

The .45 ACP has lesser pressure rating compared to the 9mm and .40 S&W and it has more recoil.

The more weight being pushed has an equal force teansmitted to the pusher. So, the heavier the projectile/ the heavier the recoil regardless of pressure.

Recoil cannot be analyzed by peak pressure alone.

eighty deuce - my thoughts with the 45acp at only 21,000PSI. now, is it possible to download the .40 to below 30,000psi but maintaining reliable slide action?

Sure, that's what different weight recoil springs are for.
