Nylon Spring Guide For Bsa Improved Model D Query

[evert]

Managed to get a chronograph......
With a 24 coil Titan spring (no preload) and top hat and washers, it chrono'd at approx 10.10 f'lbs. Using the unknown double spring set,(probably 20 year old NOS Knibbs) it ran at just under 11f'lbs. Using original 5.6mm Eley wasps.
Need to suss out which Titan spring it is, buy another and try it with more coils. A well mannered 11 foot pound rifle would be perfect and I will leave it alone. Otherwise will start looking at transfer port.

What about trying the Titan you have with just a bit more preload?

Yes could do that. But would need a few washers.....so getting new spring is probably more economic, as can try the existing spring in a 43.5” .177 rifle 😊
