When I am practicing at long range (over 60 yrds) I hang a pop can in fron of the target. It is easy to see and and it makes me feel good when I hear the ting as I hit it....which isnt every time of course

I do most of my shooting at night by the floodlights. My bag target has pretty much had the paint wore off so it doesn't show up at night.

I shoot for center of mass mostly, which helps because it's more like taking actual shots on a deer. You'd be surprised what you can do when you concentrate solely on form and repetition! My "no spot" groups are often better than when I'm shoting at spots!

1" dots on my block target in the yard for tighting my groups and hitting where I aim. 3D courses are the best for practicing visializing a dot on the target aiming and releasing best pratice for hunting besides hunting.

Hand a stand and toss out some tennis balls. makes you judge distance too

Thats some real good shooting at 40 yards.

I've been known to push golf ball tees in the wall and shoot at them. We also hang ping pong balls in front of the wall.

I like to aim at a target that is large enough for me to execute 45 shots in a row and hit it every time, even the fliers. This is the best way to train for rhythm, and repetition after your execution is 100% from lots of blank bale. I did about 1.5 weeks early this summer of executing shots at a 6" circle from 10-20 yards, then another 1.5 weeks shooting at a 3" circle from 10-20 yards. I was shooting about 500 arrows a week at that point. I still do this once a week for a whole practice session. If you can do this, then shrink it down and you would be amazed how many times you can hit a vegas x-ring in a row. When you just relax and keep it floating in the a spot trusting it while focusing and staring a hole through the X you would be surprised at what your capable of. My best vegas game I hit X's 36 times out of 45.

I like the tennis ball idea!
