simulating a long range shot
I don't think this is possible but is there a way to simulate a long range shot? I currently only have access to a 100yd range. Would shooting at a very small target be enough?
I know there are a lot of factors that come into a distance shot. But if the target was very small wouldn't atleast some of those factors come into play, such as wind drift, trigger control etc.
If the small target is a decent idea, any idea of how small that would have to be?
thanks.
after posting this I realized that would be no different then simply shooting tight groups. Please disregard this post unless I missed something further

Simulation!?
As to target size, ...shoot at a dime at a hundred. For accuracy,etc if you think of it, you are allways aiming at the center of a target no more than a pin point if posible, so a dime is the same as a man sized target (for steady hold and aimming) .
You can construct a target tree with a "center" target wwith hold over/under targets positioned at distances representinng ballistic curve of your round at increasing distances.

FNG:
Shoot a standard velocity .22 rimfire using what ever sight you use on your more powerful rifle on targets that are reduced to 100 yards.
You will find a distinct requirement to dope winds if you stick with a .22 LR and by using the sights you intend to use on your other rifle you will get used to using that particular sight / spotting scope as well as conditioning yourself to see a consistent sight picture and or holds.

Thanks for the replies, this is all very helpful.

In the first and main equation what does f represent. Is f=K so that if I wanted to know the target size at 600 yards it would be Ts=F(600,6)?

Im not totally sure how to accomplish this, but this sounds like a good idea. I googled for building a target tree and wasn't able to come up with anything like that. Do you know where I could find any data on this.

Sadly I don't have a .22 rifle anymore but I was looking at getting a .22 conversion for my ar-15. So that that should be do able once I get some funds.

There are also some very good pellet guns, which would allow you to practice in your backyard.

Thanks for the feedback. I will update the explanation to make it clearer. In this case "f" stands for "function of." When I present this to my students I usually put it into words as follows:
Ts = f(Td, A); Target size in inches is a function of Target distance in yards and Angle in Minutes of Arc.
The rest of the material is the development of the equation for this function.
Also note that once you have the equation for that function, you can easily rearrange it to solve for any variable given the other two.
Thanks again for the feedback.

fng: The NRA has downsized targets, that represent 300 and 600ranges. They are meant to be used at 200yards. If you could pick some of these up and downsize them by half, they may be helpful on your 100 yd. range. Where in PA. are you located.

That might be something to look at. My grandmother has problems with cats invading her yard anyway.

You might find this link interesting. It's primarily to compare characteristics of different ammo but also gives you control over a number of other variables:

While shooting reduced size targets to simulate longer ranges is better than nothing, it will never duplicate shooting the actual ranges, reading and compensating for the wind and range estimation.
Take a drive and find some place to shoot longer ranges if at all possible.

Shooting .22 at 50 and 100 yards/meters or aririfles at 15 and 25 meters will kick your butt if youdo not read the winds. While it will not replace longragne it will augment.
for a simple formula trythis one.
R1 x H1 divided by R2 = H2
R1 = Reduced range
R2 = Simnularted range
H1 = Actaul height of taget
H2 = Reduced height
So, R1 = 35 meters, R2 = 500 meters, H1 = 24 inchs
Then 35 x 24/500 = 1.68 inches is the height of a target at 35 meters to simulate a 24 inch target at 500 meters.
Try it at 50 meters with a 22 and then again at 100 meters with a 22 and see waht the wind does to you.

Longrange I will put that formula to the test on my next range outing.

There are quite a few places you can shoot to 1k or further.
Mifflin Co Sportsman's club
Williamsport Pa 1K club
I believe there is a 600 yard range in New Jersey now.
I go to Quanitco USMC. On the 25th we will shoot F-class at 800 yds, 900yds and 1000yds
Quote:
24 Apr. Match 1 600yd team match
Match2 1000yd indivual
match 3 1000 yd 4 man team
25Apr.NRA palma match + on the other side of the range will be a "modified" match.We'll check this venue out and see how it works.

The thing about long range shooting is that you need to actually go and do it so that you sort out your gear and your theory. Lots of stuff sounds good on the internet but just doesn't cut the mustard in reality.

I second the .22 at 50 and 100yds. I shot my first smallbore match recently and was soundly humbled.
