A father and son team started making those types of glasses, their company is called Ben Shot. I have a few bourbon and wine glasses with a .308 round imbedded in the side. The broadhead style was not available at the time.
As far as Pappy goes, waaaay over priced. My Dad would buy it for $35 a bottle before the "craze" hit. Now it is upwards of $800 a bottle, and that is if you can even find a bottle. The family only made a limited about of cases each year, then it got a great review. and BOOM, the demand skyrocketed, yet the supply is still a small run.
Try Hillrock, Solera Aged. It is a small distillery based in Ancram, NY, about 100 miles North of NYC. The original Master Distiller was from the Maker's Mark distillery. They brought him out of retirement to start theirs up. It is a bit higher, around $100/bottle than most, and some special cask aged ones are in the $130/bottle range, but it is delicious. My favorite is their Solera Aged in a Port Wine Barrel. Best tasting ever, IMHO.
As is anything, it is your taste preferences that define what you like. But I simply cannot justify paying 30X for what I know Pappy SHOULD be selling for.
