The price of the Parkers from Luke at Arrowhead is about the best around although i haven't checked directly with Parker for bulk pricing. I still have a fair amount of the Traditions branded version i got much cheaper.

They shoot so well sabotless, its hard not to use them. My NULA loves them too in sabots. I swap out to the Harvester Scorpion PT Golds for fun shooting. At around $22/50 they are one of the best bargains for a tipped bullet.

My favorite Lehighs are the 40cals and the .458 275gr. Im hoping Lehigh will make a run of 220gr .451s instead of .458s. The 458 sabots are tighter than i care to use and don't shoot as well for me in the NULA.
