Re: Interchangeable parts?

Thank you so much for the offer, although I don't have any immediate need. I guess I'm a bit of a daydreamer and often think "I wonder whether that would fit...?" Quite often any differences are not obvious from the scant detail of an item description, but if it were shown as mating with a common pa...

Re: Interchangeable parts?

I guess that's a no, then? I'm pretty sure that all the parts are available from BGAL, but the manuals on the website are all for current production models - quite understandably so. My own gun is a S400 pre-AT, so I am relying on the parts list in my own User Manual. In fact, there are minor discre...

Interchangeable parts?

I wonder if there is a resource which would allow me to identify whether parts from the 400/500 range are interchangeable? At present this is just an academic interest, but if AA or an RFD ever get hold of my rifle, they are likely to condemn the cylinder, purely due to its age - could a longer cyli...

Re: Single shot

It may not be relevant, but the Rowan magazine includes a shim that is meant to be glued into the loading channel so that it is level with the bottom of the breech. This is to ensure the pellet is aligned when the bolt is pushed forward. I've read somewhere that a couple of people said it also impro...

Re: Strange S400 Chrony results left me baffled

I left the charging hose attached so as to read from the more accurate gauge and took readings every ten shots. The resultant curve was as close to linear as you could expect with the accuracy of interpolating the gauge's readings.

Re: Strange S400 Chrony results left me baffled

It sounds like you have this sorted now, but I was thinking that the other variable you could have measured with the shot string is the cylinder pressure. I was surprised (gratified) when testing my S400 that the pressure drop is almost linear, indicating a good balance of valve spring , hammer spri...

Re: s 400 clasic

Well yes, there's always some guesswork when first trying to decipher a code! My own S400 serial starts 06.... and was sold in Oct. 2007. I suspect that there is a lot of truth in the suggestion that the serial number is allotted when the parts are manufactured so there will always be a delay til th...

Re: s 400 clasic

I'd be interested in the reply re date of manufacture. It seems that the first two digits of the serial number are the year, but I'm not sure whether they use a month or week designation and where it occurs in the serial. Just one or two confirmed by the factory should unlock the code!

Re: Loose part in pressure vessel

Although your rifle is out of warranty, I'd be inclined to take it to the supplier and try to persuade him to cover it - try citing the new extended warranty, maybe? Unless you are comfortable working on the high pressure side of the gun it will be safer to get a gunsmith to sort it for you. The par...

Re: Old Downs pursuits

Even more difficult for me to find... I haven't a clue what part of the world you're talking about!
