So why would T/C make a sabot that is this difficult to load in a T/C rifle?
As long as you are matching the pistol bullet diameter to the sabot, it really should not be that hard. I have seen where a shooter has tried to load a .45 bullet, into a .44 sabot and loading is practically impossible. Right off, you can tell as the petals will flare out. ....
Sure do wish I could see your set-up and I still suggest different sabots. .....
Be Safe !!!
