Driller212 is correct. This whole stabilize later and shoot better farther stuff is an old wives tale/internet forum nonsense.
A bullet leaves the barrel at its fastest and highest spin rate directly after it leaves the muzzle and it only goes down hill from there. When does something that is unstable become more stable later on as its spin rate decreases?
The "go to sleep" thing is related to longer projectiles (VLD type bullets) so those theorizing that the PPU needed time to sleep and the FGMM didn't have it backwards then. The FGMM 168GR is a longer projectile than the PPU 150gr and would need more time to stabilize than vice versa. Also, the BCL102 has a more than adequate enough twist rate to stabilize either or those bullets.
I fully believe that Jiffx could have better groups at 200 than 100 but it is not due to bullets magically stabilizing past 100 yards. Parallax issues at 100M get people all the time just as an example, sometimes people also get in their heads.
Also, even crap ammo can throw out a good group on occasion.
I have no doubt that with a good trigger puller and some good optics this thing can preform well for a SA. Jerry is doing a lot of testing to find this out.
