Heavier hammer spring for my 2240

[1377x]

Thank you men, these are the replies i was looking for. I will order a chrony ill attatch my barrel and shoot it . this will give me a good baseline as suggested. i dont care about making it a super hot rod but rather an efficient accurate gun while tweaking it to where you arent wasting gas once again thanks everyone

if you have an android phone you can get an app from chronoconnect its a free chrony and  works very good
i used a 1377 and discovery spring when i had a 2240 running on co2.now its running strictly on hpa i will use a discovery spring only
