Thanks for the info - you are right a 1989 barrel might be a problem for sabots. Grooves will really deep and the extruded barrel made during that time really was not held to specific bore standard, BUT I would give up quite yet for a couple of reasons.
One more question, as you are pushing the projectile down the barrel, especially on a clean bore does the force you need to exert change, in other words do the projectile go down easier in some spots and really tightin other places?
Here is another thought for you - TC shockwaves should have come with a thinner sabot than normal - BUT due to contract changes that did not always happen in fact there was a large batch of shockwaves that came out with the regular black sabot. You may have a batch of those. Look at a sabot is it Green or Black? Green usually 44 cal - Black usually 45 cal. Check the sabot cup, does the sabot have a stair step base, no plastic tit in the midlle, does it havea machine stamped number in or near the middle (not to be confused with what might appear to be a hand etched number)? If it has the stair step and machine number it should be a MMP HPH-24and that should bethe thinner sabot. Also Triple Seven, for the recond, believes that the Harvester loads easier than the 24.I have used them both and I can remember if there is a difference. The final option is the new Harvester "Crush rib" sabot. It is the thinnest sabot out there.

This is an old add, they also have 44 "crush ribs" also now.
If we can find a sabot that works for you - look at the new Speer 300 grain Gold Dot - I bet a buck that bullet would put the hurts to a hog.
Thanks mike
