I could have saved you some gas money. The only place I have found the yellow Harvester CR sabots is through Harvester.

Order some 260gr Scorpion PT's with black CR sabots to offset their shipping.

When you need more Barnes T-MZ's go to Grafs. Orders over $25 ship for $4.95. This is the 24 pack.

I stumbled across that load last year with them. 100-110gr Blackhorn 209 should do well for you.
