FX Panthera fill pressure

With an alsafe .7l tank and an m3 valve. Is it safe to fill my panthera to 300bar? Thanks
My M3 did not come with a 300bar valve on the bottle.
I had to purchase this one

Ok, was just curious. I don't plan on filling that thing ever that high. My king came with a 310b 480cc.
When you fill that high the front regulator has to fail before anything to worry about on a m3 panthera I'd stick to 3600 psi as well as most impacts even though I've seen a few fill higher really its not needed
 
It is my understanding that the limiting factors are: a 300b bottle, and a 300b valve. AirMarksman (UA) sells both 300b bottles & valves. Note that the 300b bottles are heavier than the 250b bottles.

Since the overall volume is rather small on a Panthera, I find the extra 50b useful. Next time I fill all the way to 300b I’ll let you know how many shots I get from 300b to 250b.
 
I am using the 300b AirMarksman tank and 300b valve. I filled to just under 300b and I got 9 or 10 additional shots between 250-300b.

For reference 600mm Panthera, 155b reg, 30g slugs @ 980 FPS.

That’s more shots than I thought, and well worth it when overall volume is a concern.

Are you using the standard 300CC bottle?
