What does .30 Caliber pellet compare to?

Any other PCP airgun lovers out there? I just picked up my new toy from Fedex where it was delayed for 3 days from the weather. Will be adding scope, suppressor, and bipod today.

I opened up the pellets and was amazed at the size difference. I expected a big difference, but holy cow. These things dwarf the .22 cal I've been shooting. The pictures don't do it justice compared to seeing and feeling them in person.

Left to right are:
Daisy .177 - 7.2 grains. (typical BB gun size)
JSB Diablo .22 cal - 18.3 grains.
JSB Diablo .30 cal - 50 grains.

Gun pics coming soon.
