Has anyone used these particular JSB pellets? They look like they would hit like a brick. However , their design leads me to believe range effectiveness is limited. who has knowledge on these bad boys? thanks.

Correct ...while weights higher they have a bit more energy further out ... there profile has them flying very WADCUTTER like having a low BC and limited range.
There in my experience only modestly accurate getting worse at higher speeds so IN CLOSE & PERSONAL is IMO there best use.

JSB's "Flying Barrel" functions as a wadcutter, cutting a large permanent wound cavity into our quarry.
If you shoot if fast enough so you have an impact velocity of at least 800 or 850fps, it might expand — but you'll need a very powerful gun for this heavy clunker (25.39gr).
Here's hard data (all .22cal) I have collected:
Brinkerhoff did a penetration and expansion test in 10% ballistic gel. The impact velocity was 670fps (25FPE) — very realistic for a medium powered PCP, cf. pic.
Hajimoto did a HP comparison. Nicely done. Some of the impact velocities are unrealistically high. Your pellet in question penetrated all of 9" ballistic gel (20%!) and hit the wooden backstop, so the expansion data on this pellet is useless.

Pneumatic Detonation describes (and pictures! 
) a hunting shot at a squirrel.
Impact velocity 790fps (35FPE)
Very effective, judging from the amount of intestines outside of the hide.
