Sabots
« on: November 07, 2019, 06:08:49 AM »
I wonder if anyone has experimented with sabot rounds in an airgun? I looked around the net, and all I found was info on blackpowder sabots. Did I miss something?

I have seen posts where folks experiment with them but little information and results.

I had a few packages of sabots in my shopping cart at one time but never did buy them. These were plastic sleeved copper rounds. Thought was to experiment and find reasonably performing sabots in case the lead ban was extended to airguns.

One day I’ll fiddle with them.

I think the twist rate is the main factor to whether they work or not.

The twist rate must be sufficient for the bullet that is inside the Sabot.... Since smaller caliber bullets require a faster twist rate (in inches), this compounds the problem.... For example, a .45 cal barrel might have a 24" twist, and 16" would be considered fast.... However a 4 caliber long .22 cal bullet (~75 gr.) may require a 7-8" twist to stabilize…. Additionally, you have the challenge of achieving complete and consistent Sabot separation without that disturbing the bullet.... otherwise accuracy will suffer....

It allows you to achieve much higher velocity for a given bullet without using excessive pressure or barrel length, because the Sectional Density during acceleration uses the much larger bore diameter of the Sabot.... Once they separate, then the bullet SD is much higher, and along with it the BC, as the aerodynamics revert to that of the bullet alone.... Since Supersonic velocities using air are very inefficient (and that still applies to a Sabot round)…. I question whether the whole procedure is worth the hassle, other than for bragging rights....  ;)

Bob (and Steve), I sent you an email about a special version of a sabot round.I'll let you know when and if I get an answer.

I did a lot of testing with .223 bullets in .308 rifles using sabots. http://www.sabotreloadingpro.com/products
No matter what i did, the groups tended to be 2½-3 times the size when using sabots.
That is due to the "unevenness" in the release of the projectile after firing.
In muzzle loaders shooting distances are shorter and targets way larger than with airguns so i do not think you will find sabots usefull.

But do test and keep us informed: https://mmpsabots.com/
