So is
0.3048 the same as
3.28?
I'm gonna leave the shotgun velocity as it is just like the W300. The W300 didn't have much info about it on the Net while this Remington... well, there are lots of velocities for it lol.
I'm gonna do the velocity for the M9 Beretta right now lol.
It says that it's 1160fts so I'll have to use your formula to do that, lol.
*Edit:
I did what you said and I got
0.002827... etc.
