White PowerStar Saboted Bullets

[gdc2]

I came across some White PowerStar Saboted Bullets in both 45 and 50 cal. Years ago I had ordered bullets from White Shooting Systems and they sent 4 packs of bullets I had ordered, however due to a screw up on Whites end 2 packs contained the proper .450 435 gr bullet with black sabot for the .504 rifle, while the other 2 packs which are labeled the same as the other packs contained .40 cal 350 gr bullets with tan colored sabots for the 45 cal guns. Are these still a desirable bullet either to collect or use and is there a market for these.
