Switched up tanks so went to pball shop to re chrono and got some really weird readings
Bl tested settings 70/180

Today's numbers to hit 280fps
85/210

Ninja reg shims out

Why would my numbers be so off? Everything is solid with marker, it's fairly new, stock 2012 f5

Also, when I feed neck load balls (3) first 2 shoot normal, on 2ndbshot, 3rd ball pop corns out. Is this normal?

Pressure change could be due to paint to bore match, written in orings or many other things.

That's just blow back, fairly normal.

I have limited knowledge of g6r's, but when balls pop out of the feedneck it means your bolt is not sealing correctly when firing, Try changing the o-rings on the bolt

also, you could try to sweet spot the regs again, might help.
Dwell could affect it too I believe

Factory reset on the board so settings are stock if that'd matter
3 different types of paint used (including usual field paint) yielded similar (+/- 10) results. Shop owner and I messed with mine, and used his to test feed neck bounce, his didn't do it.
Marker bought used (may as well be new) and bolt o rings either had some paint **** under them or guy used a red colored grease (was cleaned and tri-flowed) noticed there was minor residue still today.
Ill buy some rings and swap em, then retry. Just was curious off any suggestions whether it be o ring swap, part, oil or grease I might try too.
With the high pressure values it did a consistent 280 (+3/-5)

Have you checked the output of your Ninja tank? I'm pretty sure you're suppose to leave one shim in to set the regulator to 450psi low pressure. If tanks output is inconstant, you might be having to compensate with the guns regs.

[GlockMan]

worth a shot, ill pull the reg and check

[GlockMan]

Tank pressure is good, I'm going to tear down and replace some rings and grease today and retest tomorrow zeroing everything out

blowback happens in all highend markers.. doesn't matter what you shoot.

g6r, ego, luxe, clone, whatever.
