pretty easy
any rifle, any carbine, most any handgun for that matter (leastways with more than a snubbie barrel, which is really not that hard to do either given enough practice).. and that includes both centerfire and rimfire, any caliber
suggestion - never start with any new-to-you rifle or handgun at 100 yards
Start at 25 yards with any rifle/carbine, pattern the gun, learn your sight picture, adjust your sights, get your groups tightened up.. then at 50...then at 75-100
Always start with benching the gun (just resting the forearm on a sandbag will do)
If you don't first convince yourself of what gun-can-do vs you-do, you can waste a lot of ammo out guessing yourself and/or the gun. Throw at least 3 rounds in a row at each target "group" before messing with sights. You need to know what your spread is before you start adjusting those sights.
If your front post really is that big at 100 yards, go to a 6 'o'clock hold on the target.. But put a big black X on that paper that you can see for an 'aim point' anyway.. shooting at shapes several times the size of intended group size is doing yourself no favor
