Ghost .25cal Ghost tuning question

[Danman]

Interesting observation. I will have to get a single shot loader and see if there's a difference on mine. When I get the time.

On my S510 single loading is mostly impossible....tweezers? But what I do on is simply pull mag out slide pellet into mag open slot and drop it back for single loading. Or sneak one in without a mag. For a .25cal ATTK11 I would stick to 150 reg at a min to get your speeds up and a better fps range. My full mag groups all are similar poi but again my is .22.

Solo1, how are you getting 930 FPS?
I dropped my reg to 140 bar and on MIN I got 855 FPS and the speed stopped going up around setting #9 (890 FPS). That's only a 35 FPS spread at 140 on the reg vs 175 FPS (778-953) at 160 on the reg. This is all with JSB 33.95g pellets.

I am also noticing group size differences from shots 1-5 and 6-10 out of the magazine. The 5th group from the left I tried just loading 5 shots into the mag (I only rotated the mag 5 spots) and it produced similar results to the 1st 5 shot groups. This is at 55 yards setting #6 reg at 140 bar JSB 33.95g averaging 886 FPS:

Has anyone else seen similar results with mags?

First of all you guys have to realize these guns are not computers. 140 bar and pw 9 are most likely not all the exactly the same on every gun made. There might be a small difference in many things like gauges springs outside changes such as temp humidity altitude many variables. As far as groups are you weighing your pellets? Are you headsizing your pellets? Could be the mag but who knows they are good mags usually but I've heard many say groups are better single shot.you have to remember too that a 2 mph wind ( which you can just barely feel on your face) will push a 34.9 gr pellet .4” at 50 yds!
