Technically, you only hit the bullseye one time.

Even then it was only half way in the center of the bullseye.

I had a cousin that had a JC Higgins .410 shotgun with open sights that could do better than that at 100 yards.

Now - in my opinion you just wasted a box or two of shells.

Why?

Because you did not make any effort to properly sight in your rifle.

Mostly all you did was make some noise and shoot at a piece of computer paper.

Where I live, the beer distributers give out 100 yard large rifle targets before deer season - along with a bunch of buisnesses.

What does a target cost? $.25!

What does a bag of play sand cost at Dollar General Store? $3.00

You could have bought a couple of Hefty Big Bags or even sewn two blue jeans pants legs and filled them with sand and had your own sand bags for less than $5.00

Even your dirty laundry in a garbage bag would have been better than nothing at all.

Plus - you did not use seperate targets for your 30 - 30 and your 308 so there is no way to know which shots were with the 30 - 30 and which was with the .308.

So what are you trying to show us? How good you can shoot?
