You have a weird list.
That's a common handgun caliber.
That's a .22. That's a varmint load at best. I don't know why you're stuck in these calibers. Two extremely common calibers, possibly the most common, .30-06 and 308, both regularly do about 2800. A .300 Win Mag--very common--does more than 3000. Mine do something like 3300, in fact. The .50 BMG you mentioned, by the way, is well over 10000. A 12-gauge doesn't even compare.
Uh, okay.
I see now, troll? looking for a internet fight? What is it cause I have already done said I am finished. You dont even have the comprehension to comprehend I said that a slug could go through two bodies and the only sniper rifle that could do that would be a BMG .50 caliber sniper rifle. Who gives a [censored] about the muzzle velocity, you can tweak that by varying the powder load out. Why do you think "target" load outs have such a smaller muzzle velocity and fps compared to standard. Thats cause they have less powder in them. In the end you dont have no way to prove that yours does something like 3300 unless thats what it says on the box and even then it would vary based off the gun.
I mean god muzzle velocity can be tweaked in numerous ways, you can shorten the barrel to increase muzzle velocity, you can increase the powder load if you load your own rounds, hell you could even go with a larger powder load round. I can get what is called a .22 LR magnum round for the .22 I have which is basically a .22 LR round with a magnum powder load out provides the same exact muzzle energy as a .22 magnum. Hell I could take my 12 ga pump and saw the barrel back shorten the barrel and boost it up like a mini hand held cannon. The muzzle energy would go way up and it would probably shoot more like a 6 ga than a 12 ga.
In the end as I said drop it, it wont be long before a mod gets involved over this drama that you are starting and draging out even though I have already said once to drop it. Now if you want you can reply back dragging this out more but I wont say that I wont send in a report about you trying to start arguments and trying to keep the thread off topic after I have tried a second time to drop this.
Oh yea I wanted to throw this in there just for you.
.308 Win. Mag. = 2648 ft/lbs
.30-06 Spfd. = 2342 ft/lbs
.300 Win. Mag. = 2540 ft/lbs
Those three are specs listed for the first rounds of each of those calibers I found. So only thing I can say is if you are using 3300 ft/lbs out of a .300 winchester magnum then you must have a overloaded powder load on those or you have a shorter barrel.
