john-aas410 1 Posted July 17, 2009 Report Share Posted July 17, 2009 I have a BSA lightning XL in .177 as a spare gun, which is being used more and more by my son. He unfortunately is struggling a bit with the recoil, and I was considering replacing the spring with a gas ram, for the smoother action and reduced recoil. However I am concerned about the potential power increase as reported up to 18ft/lb in some articles I have seen. I am not an FAC holder, and have no intentions of exceeding the current power limits. Can anyone offer any sound advice based on experience or true knowledge to help me out. Kind regards John Quote Link to post
SEAN3513 7 Posted July 18, 2009 Report Share Posted July 18, 2009 (edited) it is very unlikey that a "standard" gas ram will exceed the legal limit. the easiest way would be to have a gunsmith fit it and set it up. or, if you want to do it your self buy a crombo chrono and then you can test it as and when you like. as i have said.......it is VERY unlikely to be over, but always best to check atb sean Edited July 18, 2009 by SEAN3513 Quote Link to post
aaronpigeonplucker 32 Posted July 18, 2009 Report Share Posted July 18, 2009 im fitting a gas ram on my lightning xl and havent tried it yet but i am looking forward to it. Quote Link to post
Big bald beautiful 1,231 Posted July 18, 2009 Report Share Posted July 18, 2009 easy...but a .22 in a .22, it will be nice and safe at about 11ftlbs. fitting a .177 to the .22 will make it 16-18 ftlbs, no good as it will shake the lightweight gun to bits, besides you getting done.

brock1 2 Posted July 18, 2009 Report Share Posted July 18, 2009 if you fit the right gas ram for your gun. it will not be over powered. ps make sure u get the lightning xl gas ram becouse if you use a standered lightning ram it will be under power. i have used one for years in my excel with no problem with the power.

The Gas Ram is the power plant what ever gun you fit it in, it is up to you to fill the Gas Ram via the HE pump to get the correct power output, if you overfill you will not be able to break the barrel as the Gas Ram will be over gassed, you will need a chronograph to check your work, a Punch to degas & the HE pump & adapter for either Theoben or HW depending on the ram you use to fill, it would be highly unlikely you could put the gun over by much as you will not be able to cock the rifle without bending the barrel & overloading sear & pawl with a trigger release that will feel like 30lbs. This system is fail safe & idiot proof. foxon. Quote Link to post

If you just state clearly the exact make, model and caliber of your gun to whoever supplys the kit, you'll be fine. Cheers. Quote Link to post
