Ever since i got a new target i can't shoot worth a da$@ i don't know what is going on, ever have this problem. Oyeah the target area also got bigger if that has any thing to do with it.[:@]

What target is it. I have the block, but I hate the dots. Instead I turn it around and stick a pinecone in the back. I can shoot straight like that. I also pick out a part that sticks out. What do you shoot at, a bullseye?

A deadstop bag

With bullseyes?

shoot an arrow at the target. Then aim at the nock of that arrow. This will help your concentration. When you start busting off nocks you can start aiming at the separate bulls on the target.

The size of your target area can definitely have an impact on the size of your groups....it is part physical and part mental. Physical in that you don't have as small of an aiming point to focus on. Mental in that most archers became a bit lax in their focus when a larger target is presented.

I have much the same problem when it comes to certain color target faces. I can shoot great if it is two colors...a light and a dark one. Throw in three colors and make them all light in hue and I can't group worth a darn.

To help me focus on larger and darker targets I use those bright red target shooter dots you can get in the sports department. They are easy to replace and I can put several on the face of the target so I don't damage my arrows

Everything said so far is true. Maybe you've heard it said concerning deer hunting, "pick a hair and shoot for it." The point is, you need to aim at something small.
I think the same is true of your sights. I prefer as small a sight pin as possible so that I can aim as precise as possible.

I have the same problem with spot targets. My groups open up a good bit with the blue three spots and even more with the bright red and yellow targets. I like to pick out a small blemish on the target and shoot for that. I can stack them all day long like this.

That's the way that I like to practice. After all, a deer don't have big bulls eyes painted on them do they?

Blame the target. Good one.
