Thanks, Eric D. for mentioning Eggleston Munitions in your post.
I just checked their website, (to look @ their prices) & was surprised to find load data for their bullets!

Was curious to what coating they used & read it's their own formula !
I've used quite a few Bayou and Falcon coated bullets in my pistol handloads the past few years..
(both use Hy Tek brand polymer coating) and have been impressed with the results.

Though projectile cost is a little higher (no 1K price ? !) their shipping cost is lower..
and the bullet hardness is a little higher, maybe why higher velocities are claimed capable ?

Looks like I may be placing an order with them in the future.
Both Bayou & Falcon do offer a much wider assortment of bullet weights & shapes, per caliber, available.
