Wow, that's a great idea wyz! I should try that And what cannon was that in the beginning of the video?

That's my hybrid cannon.

Very nice tutorial as always
Here's another method: http://www.spudfiles.com/forums/sabots- ... 23677.html
The two can be combined, you could have a foil or paper wrap to centre the projectile then add a wax base.

Tutorial are like intros, with your own imagination that how things will work for you
There are many ways, I just point a direction.

Thanks for the inspiration, got off my ass this weekend and had a little fun:

I was quite surprised at how effective and tough the sabots are. Although the wood was probably only radiata pine (i.e. a soft wood), I was pleased with the .223 and crossbow bolt penetration. The slug filled with 3mm BBs was also quite cool as the entry hole was the size of the wax slug but inside the hole the BBs had expanded out and formed a BB ring like a bearing.
As you've already demonstrated, wyz, these slugs are suitable even for hybrids.

Don't you hate trying to match steel ball bearings and
inner diameter's of various tubing/pipe materials!
Very good idea wyz, are they accurate though?

Wax is reasonably light so if you shaped the wax in to a more aerodynamic shape with the ball bearing as the front of the projectile, you probably could get better accuracy than just shooting a ball bearing. Now that all depends on things like range, weight and performance. But at a decent distance a spherical projectile will dip, rise or curve to some degree* whereas an aerodynamic shape like the bottom drawing in the link above will only have gravity affecting its trajectory after leaving the barrel.
*a sufficiently heavy projectile, relative to its velocity, probably wont rise, dip or curve uncharacteristically. For example, a 10mm ball bearing will probably only dip in trajectory at ~200fps over a medium decent because it is too heavy/too slow to be affected by things like wind or spin.
Anyway, that's pretty much all assumption on my behalf; I doubt that actually shaping a wax projectile will be worth the extra accuracy (if it does result in any). JSR will be able to weigh-in better than I.

Yes,... i have found the difference in accuracy is notable between 6mm and 9.5mm
steel ball, hence the difference in weight and wind effects that occur. Have you seen the
ammo that the Benjamin rogue .357 cal air rifle uses? Something like those would be
perfect.

Good stuff MrC! Now if only we could introduce you to that friendly machinist...
I don't know why I was reminded of this amusing set of reviews for Veet hair removal cream for men:

If you make the wax slightly larger than the barrel bore, a "potato" a like air-tight fit can be archived. I was able to shot through a laptop screen with a nail using 3 bar with a 1.5l water bottle 3/4 ball valve gun, the tight fit completely compensated the slow opening valve. Check the shot at the end of the video, you can notice a delay between fully open the valve and the shot.I was quite surprised at how effective and tough the sabots are. Although the wood was probably only radiata pine (i.e. a soft wood), I was pleased with the .223 and crossbow bolt penetration. The slug filled with 3mm BBs was also quite cool as the entry hole was the size of the wax slug but inside the hole the BBs had expanded out and formed a BB ring like a bearing.
As you've already demonstrated, wyz, these slugs are suitable even for hybrids.
Also, with a wax sabot, rifling can be effective in any cases now. But for hybrids and combustions, you probably need more wax as some of them will burn off.
