HW100 issues

[MattF]

Morning all,

Looking for some advice, 177 HW100k with A&M cylinder.

I haven't used it for a while, tried it yesterday and the POI at 25 yards had dropped about 3 mil dots.

Removed cylinder which vented any air left in it, put cylinder back on, refilled and appears to be back to normal.

Is it a cylinder issue or the reg in the gun sticking?

Cheers all

Sounds like you’ve got a leak. My advice is to fill the cylinder off the gun and leave it not connected to the gun for a couple of days. If the pressure drops it means your cylinder is leaking, if it’s only leaks when connected to the gun, every chance it’s the gun

I understand A & M cylinders don't have a valve so vent when you take them off. Are you aware A & M will check and service it free of charge every two years if you send it to them at your expense?

The best cylinder on the market is the HW100 Tuning Titanium one, much safer than alloy, also gives a real improvement to performance.

Did you fill your gun up before you stored it?
If not problem may be solved...

Probably around 150 which as held.

After being stood unused for while, many guns seem to need a few shots to liven them up!
If all is now OK, problem solved.
I shoot bench rest so I always shoot a few shots before even checking zero.

Drop in POI is not a cylinder issue so long as it has air at pressure above REG set pressure. POI drops are usually power related and a gun that has been unused for a while may need a few shots to clear its throat. If the gun is shooting noramlly now then all is good.
