"the gun trade is very secretive...."

Read my previous post again.



There was a very early 20th century, pre first world war, trade magazine called Arms and Explosives? I read an article in an edition which detailed in several pages experiments carried out by BSA using the Lincoln Jeffries patent underlever rifles they were making at the time. They experimented with light and heavy pistons eventually settling on the heavy for best overall performance in their production air rifles

That doesn't sound very secretive to me
As well as I can remember JB gave details in Airgun World of what he did in his air rifle conversions including information about piston heads, weights transfer port sizes, barrel locks, adjustable hinge bolts etc. Is there anything specific you want me to ask him tomorrow? Why don't you ring him and seek his advice yourself? It would save me the cost of a phone call

you think jb would talk to me lol.....dream on man...in fact I would not dream of asking him as I prefer to make my own notes.

you seem quite hostile with me, I think it best we do not comment on each others posts going forward, we do not want to upset the admin now.

I respect your opinion, please respect I have my own too, if I offer advice its up to the in decidual if they choose to except it or not.

thank you

Everyone is entitled to their opinions and the right to state them providing it does not cause offence. I respect that. When a puzzling comment is made it deserves a response. Hopefully that response expands on the matter. That is called a discussion. That's how we find things out.

just do your own testing and make your own decissions....thats the best way...and what i do.

until you test it yourself how can you be 100% sure....i dont take anthing for granted until i have tested i it.

It would be nice to see you do some testing on a springer, with stroke, transfer port and piston weight all covered freely publushed on the forum :-)
