Bsa Lightening Question

[hobble 11]

Hi I've just been given my fathers bsa lightening xl se grt, want too keep that untouched , my question being...I also own an old british built bsa lightening fitted with a theoben gas ram..I've heard that a hw 97k spring will fit, now will that make any great difference to my guns performance and will it cause any long term wear to the rest of the gun...something I may consider doing depending on my responses on here! I've no need to go out n get a different rifle as some may suggest as I already own an air arms (pre anti tamper) s410 carbine.

Any advice would be appreciated

If your lightning with the theoben ram in , and the ram is the correct for the gun .caliber model ect the power should be bang on full power 11.8 ftlbs mine was .BUT the ram may become faulty mine did it stared to loose pressure and oil and started to shoot at 11 ftlbs .my gun is a 177 I replaced the ram with an xs spring and and a spring guide made to fit the spring exactly .shooting the gun now it is smoother than the ram and shooting 11.6 ftlbs constant .but the spring in a 22 I think some spring would have to be chopped of .

Thanks for the reply barrywhite , my ra. In the gun is fine but prob will get it chronoed...as I now have a gunas standard with a ram in it I thought it wld be nice to have a normal springer not necessarily standard spring but springer and doesn't matter if stock spring or not although I do still have the stock spring.
