I don't remember the numbers but I think with a proper sight in,
the 30/30 will drop about a foot at 250 yards. I beleive that's if
you put it dead on at 150. These are guesses on my part I'm not
sure of the exact numbers. Look it up on line. I think you are
kind of pushing it to go out to 270 yards. How do you know you
weren't hitting to the left or right at that range? Better get a bigger
piece of cardboard to shoot at.

Slim,

Below is a printout from a ballistics program I use. The problem is that you sighted in so low at 100 yards. The way you sighted in you're going to be more than 16" low, at 270 yards. Now, with that 2nd shot, you maybe should have hit the box, but as ZB pointed out, you really need a bigger target so you can figure out where you're actually hitting. When in doubt, always sight in 3" high at 100 yards and remember that all the paper ballistics in the world are only a guideline...the only way to know what your rifle will do is to shoot frequently at the ranges you're interested.

By the way, the data below is for the Leverevolution ammo, 160gr bullet at 2400fps, out of a 24" barrel. Your carbine barrel length is going to give up quite a bit of that velocity...maybe 200fps, or more. That probably explains why you didn't even hit paper at 270 yards. If you can give me the chronograph reading for YOUR gun, shooting that ammo, I'll try to give you a better idea where to sight in. Generally speaking, though, I would suggest a 3" high setting at 100 and keep your shots no longer than about 225 yards. Still pretty great range for a cartridge older than my grandpa!

Slim,

Anytime I want to test for long distance I work my way out to it so I know where the bullet is hitting.
I usually sight in at 2" high at 100 with any round I'm hunting deer with, then I take a good size background with a target on it, and back it up 50 yards at a time. It takes a little more ammo that way maybe, but then I know where I'm going to hit at any range in 50 yard increments out as far as I want to go.
You have gotten good advice from the other guys here, and I agree that a 20" carbine may not be up to shooting 270 yards, where a 24 might just give enough extra to be able to. I bet you can reach out to 200 to 225 easily enough anyway. I don't know about you, but 200 yards is a **** of a long shot for me unless I'm using a scope with some magnification. I may have attempted it with a peep in my younger days, but those days are far behind me now!
Happy New Year, and I hope this helps!
