The ten foot chart is mounted on the wall with the very top edge at about 78" from the floor, it hangs down 36". You use it from 13' (16 yards) back to 24' (27 yards). I use it a lot about 20' from the wall it is on.
The 8 footer is mounted on the wall with the top edge at 73" and it hangs down 30". The 8 footer is used from 10' (16 yards) back to 19' (27 yards). I use it a lot from about 13 to 15 feet from the wall it is on.
If you haven't got about 16 to 18 feet of room to get back from the wall it is on I think you are better off with the smaller 8 footer. The larger one is a like watching a bigger TV its a really a great chart if you have lots of room but
I use and like them both. When I am getting ready for a big shoot I just use whatever customer's chart is on the wall at the time. If no chart is currently on the wall I always put a large one up for my dry-firing practice.
My basement is narrow and I just stay in the post 3 view. I can move a bit sideways and I can get like where a post 2 would be (about 5 feet over). If you have room to move sideways a bit that is fine but it is not necessary. I have used the Wall Chart this way for 30 years with good success. The amount of actual gun movement is about the same for all posts. When you can move smoothly anywhere in the “Vee” shape the chart makes you can shoot any post.
I change my hold points sometimes by holding off to the right of the trap house and make a longer physical move to the sharp left target or reverse that to make a longer move to the sharp rights. By varying your hold points a bit left and right and heights of the hold you can be ready for any length of gun move you will see on a real trap range.
I will have some wall charts with me at the Silver Dollar in March, getting one from me there saves the shipping fees.
I did good there at the Dixie Grand and at the Hall of Fame Shoot winning 7 trophies, a gun and a bit of cash. Now unless the trap Gods have changed I will go down there next month and probably give it all back.
I am hoping chart orders this week are real slow I am way behind on everthing.
Here in Ohio this morning it is 22 degrees with a lot of snow and ice on the ground. It is around 10 AM on a Wednesday morning. There are no gun clubs open for me to go shoot some practice. Besides who wants to shoot in this type of weather. All you do is develop some bad habits. So, why am I passing all of this BS on to you folks who are wondering about buying one of Terry's charts. I have already shoot 100 targets and 50 pair of doubles this AM in a pair of shorts and a tshirt in my basement using Terry's chart. It cost me nothing. I saved the cost of gas, shells and the cost of targets. Now when the weather gets nicer, I can go shoot 200 "free" targets. Think about what it cost (targets, shells & gas) you to shoot 500 targets at your club. Then compare that cost to the cost of Terry's chart. You will have the chart for a life time. How about the guys who would love to shoot an extra 500 targets a week but just do not have the time or funds to do that!! You know what, I think I will just go shoot another 100 of free targets! Love that chart, mine is not for sale!!!!!
