That's really the truth Mike.
I've seen several "new" calibers in the last several years that were gaining popularity for a while, but seem to be losing ground.
RAR30 and 300 AAC blackout to name two, though to be fair, the blackout has been around for a long time under various names with minor changes mainly because there was no SAAMI standardization until Cerberus/Remington/AAC got behind it. I have heard it called many things.
That latter may be around longer with better ammo availability and their intense marketing strategies, but from the promises that Robert Silvers made about mass availability simply did not hold true for various reasons.
Even a year before the school shooting, commercial availability for it was more in very limited spurts rather than "readily available almost everywhere guns are sold" which has put off a lot of people who don't handload for it.
But back on the subject, I'm glad you got the bow. I'm looking forward to hearing a range report. Lately my youngest son and I have been alternating between an old longbow and a youth compound playing around in the back yard.
Admittedly, I have very limited experience in the archery field, though my oldest son placed 3rd overall in the state for Freshmen High School several years back when they had an archery program.
He has a lot more time behind one than I do. All I can do is decipher a few specs and cover the basics LOL
