With the right bullet and shot placement (center body), a .22/250 will not leave a mark on a chuck even at less than 50 yards. The bullet will explode inside turning everything in there to mush, without ever exiting the chuck.
Highly unlikely. Anyone whe has ever shot a groundhog with a .22-250 of even the .22-250 will probabally agree with me that they really mess up a groundhog, especially at 50 yds.
@50yds, a head shot leaves no head left and a body shot, leaves two halves sometimes only connected by a little skin.
@100yds, pretty much the same thing
Beyond that, still pretty messy just not as bad.
If you don't believe me, I have some pretty good pics to prove it but they are very gorey so I won't post them unless someone insists.
And while I agree that the 22-250 is faster and flatter-shooting, I still defend the .223 about your comment of them not being in the same league. The distances that it takes for there to be a substantial difference in bullet trajectory, is well over 3ft of drop and about 500yds. And at that range, wind and shooter error play a lot more role than the abilities of each round.
I know g-hogs can be tough to kill, but the key points to keep in mind are newbie shooter, and close to neighbors. .22's are perfectally capable of taking g-hogs @ 75-100yds in the hands of a good shooter. I know because that is all i used to use. And the only way to become a good shooter is to practice, and .22's are as cheap as they get. Just get a good bullet trap or make one to shoot into and you can practice all day for ust a few dollars.
10/22's are good, but if you really want the best accuracy, get a bolt action. I got rid of a 10/22 because it wasn't accurate enough for me. I use mine for squirrel hunting, and being able to head shoot one at 50yds was tough with the 10/22, as semi-auto's just arent as accurate. I have a Marlin 880sq and it will shoot 5 shots at 50yds under 1/2inch group.
For a new shooter, I would reccomend a scope. a 4x or 3-9 would work. What ever you decide on, practice and practice some more. You want to be confident that when you put the crosshairs between his eyes at 50yds, that your bullet is going to hit there.
