Ok.....My O-SAST results were as follows:

4.5oz. stone reached 121yds. using an overhand throw with a 2 step follow through.

Same stone cast 278yrds with the figure eight overhand sling technique and a 2 step follow through.

For an O-SAST ratio of 2.3/1

Interestingly.....a 2.7oz. stone, thrown underhand, reached 71yds using a two step follow through while the same stone with an underhand sling cast, single windup, 2 step follow through, reached a distance of 384yds. for an O-SAST ratio of 5.4/1

Of course, there are many variables to consider upon careful examination of such an exercise......a highly palatable apple and orange tossed salad, if you will.


Fun exercise MG, I must admit to having been curious as to the ratio over the years, but not enough to have crunched numbers before your proposition.

A while back I saw a chart of effects of base altitude on projectile distance assuming a constant angle of release. Altitude changes of many hundreds of meters did not have a too great effect on range, maybe up to 9%.   

There is also a correlation between distance and release velocity. Our proposed project might reveal some eye popping results!!!
I hope the data is an improvement over some on our current ranges chart.

Wow this is quite interesting. heres my contribution.
over hand base ball style throw 24.03 paces
over hand sling 59.06 pace a ratio 2.04/1
under hand throw 41. under hand hurl 96  ratio of 2.03/1
the ammo was 4ounce waited tennis balls. the sling was 43inches long.

Were they weighted by filling them with water?

OK, I was out with the dog and a tennis ball this morning, decided to see what I could do.

Tennis ball, pitched like a baseball: 26 paces.

Same tennis ball, slung nwmanitou style with an Apache-length sling: 50 paces.

My O-SAST is thus 50/26 = 1.92.

26 paces?  What a WIMP!

Naw, about two and a half feet per pace (about three-quarters of a meter).  Let's see, that would make it ... 65 feet and 125 feet (19.5 and 37.5 meters).

TechStuf, you THREW a rock, three times as far as I can SLING a tennis ball!  "Apples and oranges" of course, but ... wow, man, good arm! Bray's record in 1982 was 478 yards, you are four-fifths of the way there!

Thanks Dale...In my younger days.....I could throw a 2 to 3oz. rock to 150 yards or so.  Since I bulked up (ie. got fat)....I throw heavier ammo so as not to throw my arm out and can't put them out there as far.  But I'm ready for my second wind any day now.

1/ Sling = Mid-length, 34 inch folded
2/ Delivery = 1-3/4 turn underhand style
3/ Ammo = Tennis balls weighted to 3oz (80gm)
4/ Grip = Apache style
5/ O-SAST = 2.1

1/ Sling = Mid-length, 34 inch folded
2/ Delivery = 1-3/4 turn overhand (nwmanitou) style
3/ Ammo = Tennis balls weighted to 3oz (80gm)
4/ Grip = Apache style
5/ O-SAST = 2.2

Comments: 

If I slung underhand, I threw underhand, and if I slung overhand, I threw overhand.  My overhand throws were about 31 paces, while my underhand throws were closer to 25 paces, so while the 2 O-SAST numbers were about the same, I actually got almost 50% more range overhand.   I attribute this to simply letting go of the ball higher in the air, ....like throwing while standing on a tabletop, so no surprise.   It's best to compare overhand to overhand, underhand to underhand, sidearm to sidearm, etc, I think.

My O-SAST with a 20"sling was just 1.7, so the longer sling gives increased range, but not as much as I might hope for inasmuch as quite a bit of accuracy is sacrificed.

Is O-SAST highly ammo-density dependent? 

Using tennis balls weighted to 3oz (80gm), my O-SAST with a 20inch sling is consistently about 1.7.

Same ammo in a 34inch sling is consistently about 2.1.

This doesn't seem like enough difference between the 2 sling lengths!!   But maybe the tennis balls "die" in flight, and fall to the ground.

If I used (say) 3oz steel ball-bearings would I:

1/ Increase my O-SAST with both slings?

2/ Widen the difference between the two sling lengths?

What do you think?   Guess I'll have to get a bucket of landscape rocks and see.

Most areas have rock companies that will load your pickup or deliver 'Pea Gravel' to your site.  This gravel usually provides the best favorable ratio of usable ammo. Check your local provider for sizes....the cost is usually reasonable.

As for the ratio being dependent on ammo density, surely so.  The size to weight ratio of various ammo choices will factor to one's OSAST results.

Somebody just suggested we measure power of the sling by comparing with the power of a bare-arm throw, so I am bringing this topic to the top.

Sling Length = 34", polypro rope construction
Ammo = Tennis Balls, 2oz with no weighting
Delivery = nwmanitou Fig-8 overhand
Grip = Full fist Apache style

All of a sudden things are really working!!  Balls that "normally"  landed 10ft from the back of my house, were bouncing off the second story wall and roof!   Also, flying straighter.

I have to estimate O-SASTs of at least 3, maybe 4 or more.  Hard to measure with the house in the way.

I think the secret is that I was consciously delaying slightly the final snap.   It may be a rule:  If you're hooking and not getting enough range, you're rushing the shot.

I went to 2oz tennis balls, instead of 3oz to reduce range, ...and let me recover the balls.   Maybe at my age, speed and strength, 2oz is a better "load", too.   Don't know.
