JSB 15.89 .020, How Are They Performing For You?

This group @ 85 yds with Az tuned rapid @900 fps. Of the 4 pictured the new 15.9 is the winner in my gun.

.20's in a good barrel just shoot great PERIOD !!

Work great out of my LW barrelled Gen 1 MRod at 900fps. One hole at 25yds, 1/2"at 50yds. Haven't had opportunity to shoot any further

I shot a couple tins of them through my Raptor, from 22-32fpe. I was surprised to find that this particular LW barrel seemed to prefer the 13.73gr JSB over the 15.89. 

With the 15.89, about 80% of the group would be extremely tight, with the rest being outside the main group. 

This was 12 shots @ 55 yards, and pretty typical. 9/12 are REALLY good, with a couple flyers. 

This was shot with reg pressure too high though, and fps was a little wider than I'd like. I plan to revisit these pellets with an appropriate reg pressure and see if I can make 12/12 be in that 1/2inch group.
