The formula for simulating distance...?

Postby machineman9 » Thu Aug 21, 2008 5:41 pm

My friend has an airsoft pistol (and maybe sometime soon I might get one too) and we spent the other day trying to do some target shooting in my room... It was a terribly drawn set of circles, but it was good fun.

He asked me what distances I shot when I did archery, and I said a gold ring size of 10cm at 25m. I then wondered how we could simulate this distance without having to find a strip of land 25m long.


So I am just wondering if anyone knows a formula to make a target feel like it is 10cm at 25m, but in actual distance the target is more like 2 or 3 metres.


Any input?


Cheers

I remember in USAF we shot a simulated 100 yard target (I think) but we were actually just 50 feet away in rifle and in pistol it was a simulated 25 yards (?) from 25 feet. Sigh, it's been too long to remember the particulars. Unfortunately, I always shot expert and didn't get to requalify but once every two years.
I have no idea how to reduce the target silhouette but there must be a formula out there. Targets like that can easily be bought, over here anyway, to simulate distance. What they can't simulate are variables such as wind and bullet drop.

Yeh the flight physics would be messed up a fair bit. I am just trying to get more bang for my buck. Shooting 10cm at the distance I have available is easy even when shooting from the hip. It is just to try and make it so that it seems I have more metres of range.

Well, I was rooting around and found some old unused targets. This probably won't help much, but a bull on a 6 inch target fired from 25 yards simulates a bullet striking approximately one inch high at 100 yards. The bull on this one is 0.5 inches. Of course this is for a centerfire rifle, not an air rifle.

[color=#003300]For mathmatical simplification, we'd set a 1cm target at a distance of 2.5m to simulate a 10cm target at 25m. Aside from wind effects (get a good fan and simulate shooting in a hurricane) and the different gravitational effects on a small air pellet, the aim variation must be accounted for.

Genius moment strikes....

Haha, yeh that does make sense. I am suprised I didn't think of dividing both sides by 10  ;)  *Probably the 6 weeks of eased off thinking*


Not completely accurate, but hey it would work.
