.20 Cal JSB Heavy
What do you guys think about the JSB Heavies in .20 cal? I’ve been shooting the normal JSB .20 cal domes out of my TALONP 12” barrel and it loves them.
HAve worked in the 5mm's I have at hand (4 of them).
Not so much in the only springer....not worse, just not better.
Win in the co2 and two PCP's so long as it is pushed no faster than 920-950fps (which is pretty hot for a 5mm) are working quite well.
I have my MRod tuned to shoot them avg 925fps. One hole at 25yds, 1/2" at 50yds.
Group shot @ 85 yds with new jsb heavy 15.9 @ 895. One 12 shot mag . Az tunes rapid mk ll .20 cal
I shoot the heavies in my Leshiy with a 250mm barrel. It's backed-off to 600-ish fps so the neighbors won't notice. At the ranges I shoot (13 yd to the pecan tree) the POI change is negligible when using the lighter 13.73's, but the heavies smack a little harder.
In my rx2 they are horrendous. I would trade them in a minute for some old beeman fts.
