Hw100 Recoil?

[PeskyWabbits 464]

I was out last night trying to zero in my borrowed night sight - it is an ATN monster. Like having a 3 litre coke bottle on top of the rifle.

 

Anyway. It wasn't going well and after the third magazine, something changed.

Recoil. Detectable recoil. Not like a spring gun but definitely there.

 

The pressure is still in the green zone.

The pellets are the right way round in the magazine.

I don't think there is a blockage.

 

What do you reckon?

 

It is an HW100 KT .22 about 2 years old but I have had it about 3 months.

 

Thank you

Put it over chono, sounds like a power spike

One hell of a power spike! The FAC HW100 @ 30ft lbs has no recoil. My 17HMR at close to 250ft lbs has virtually no detectable recoil!

I will ask Santa for a Combro. I tried pumping it tonight but it is more of a struggle than usual.

Not had chance to fire it. Will update tomorrow.

 

Thanks for the advice

newton`s law makes it impossible for there to be no recoil, it`s the violence of it that makes it more pronounced, that's why with powder burners slow burning powders give less felt recoil, maybe with air guns its down to how fast it releases its dose of high pressure air

It could be the rear of the action. There is a slight amount of movement, and I mean slight, fractional even, to the 100's rear action [behind the magazine] as its in 2 parts where the magazine resides in production. If you have a hefty NV kit mounted on that back rail [behind the magazine], if it be effect the balance of the internals of the action.

 

This would of course have an effect on hammer and spring causing vibration on the firing cycle.

 

Just a shout. Of course.

I think you are right Rez. I shot topless and it didn't have any recoil

So I put the sight back on but moved forward and no recoil either

Thank you very much to Smithie on here. He lent me a Combro which I have used on all my rifles.

 

The HW100 is averaging 10 foot pounds. I am surprised it is so low.

This must be because I am a top of hill dweller and the altitude is affecting everything.

The pellet weights are manufacturers figures. My weighing scales are calibrated for making buns not tiny bits of lead.

 

Thank you for all the replies.

I will do a full write up of all the results on a separate thread.
