About 200-400 fps max. Depends on barrel length, load, type of rifling, etc. The effective range could increase another 100 yards for a good shooter. It would make a 6" barreled pistol at 50 yards a 150 yard carbine.
For SASS shooters, and on a farm or ranch, the shooter gets the benefit of some extended range with a common caliber. It doesn't make it a rifle, tho, and a 250 yard shot at a deer or coyote would be questionable.
The basic problem is that it is a short fat bullet that loses speed rapidly, compared to the long, skinny rifle round of equal weight that doesn't shed velocity with it's better aerodynamic profile.
We recently bought patio doors for a remodel, and while unloading them (stick with me,) had to walk around the house to store them in the basement. Once clear of the house, the south wind caught the full face of the doors and it was a struggle to hold it up until it got turned edge to the wind. Then it was no problem.
Large frontal areas mean more energy transfer sooner, but lose velocity quicker. Everything is a tradeoff.
