Regardless of the platform, what you really are asking is "Is it challenging to hit a paper target at 100 yards with a .22LR round from a 4.5" barrel" Depends on your sights or optics.

No different than a 4.5" pistol. I know people shooting saltines at 200 yards with a .22LR rifle The round can do it. Just need the optics and to account for the drop and any windage.

Decent trigger and optics, sure. should be fun.
