Why limit yourself to JSBs only? And look at the Predator GTO

Well....it's a rhetorical question, because JSBs are known for their exceptional accuracy and consistency. I only have opportunity to target shoot so my pellets are limited to domed types. Recently I tested a new FX ST .25 barrel and realized that I only considered using the .25 Kings, MKI and MKII. But I know that in .22 the H&N Barracudas are as accurate as the JSBs in some rifles like my Daystate. So I looked up on Pyramyd Air and noticed that there are .25 H&N Barracudas and Trophies. Are they worth the try? What about (target-type) pellets made by others?

I also found this new (light) pellet called the "Predator GTO" in .25 Cal (only 16.54gr) which looked interesting. So did some search and sure enough ..it's made by JSB and claims to have beat in competition other pellets already. How much different is the Predator GTO from the lead-based JSB version...i.e. BC?:
