Bonded 225g 40 caliber Fury Bullet
This 40 caliber 225 grain FURY bullet was provided by Omega45.
The distance between the rifle, and horse was 25 yard. The powder load was 80 grain Blackhorn.
The bullet destroyed the front jug, did even more damage to the second jug (blew it in half), blew up the third jug, and was caught by the fourth jug. It now weighs 199.7 grain.

Your long and narrow (250/40) may need magnum powder charges at 150+. If not, then keyholing might occur.
That was my experience when I ran PRBullet's 250/40 a few years ago, using 85gr GoexFFF. Mine was a boat-tail design in a 50-cal barrel and could have contributed to it going sideways.
If yours is non-boat-tail and inside a 45-cal barrel, you may see better results at longer distances. If you experience keyholes, try using bore-butter in the sabot-bottom cup, or try a fiber wad.

Im using a 1-20 and 1-22 twist 45s. Ive already ran the stability estimates and its fine even with medium loads. The 40-250gr is .998" long. JBM says its fine even at 1800fps in a 1-22.
Bore Butter will never touch my barrels ever. I never seem to have any issues igniting BH209 in my rifles so i cant imagine how putting anything on the powder side of a sabot will help. 250gr for a 40cal is pretty heavy and my bores are not loose. Ignition even with smokeless in the SavPac should be flawless.

No bore butter for me either. Been 20 years now and only had the shakes / withdrawls, for about six months.
FYI.... when filling the bottom cup with any semi-hard patch lubricant - for the manner I described in my post the other day, it won't make any mess of your bore.
I would never ask anymore to apply a bore wall with bore butter.
Yuck!
