I have a new Taipan Vet 2 tactical that has developed a slow leak. It is the 700mm version in .22. I can fill it up - I did 250 bar then 215 bar - and let it sit and in 4-5 hours or overnight the pressure is under 50 bar but not to 0. I got the gun from Tony and told him and he said to try the soapy bubbles around the pressure gauge. Has anyone else had this problem? And what is the best "soapy water" fluid to use as I have never had to do this before? I'm guessing that I could use soapy water and then clean and lube the hell out of it when I'm done. I also saw in another forum that someone said to put a balloon at the end of the barrel to see if it's leaking there - have not done that yet either. Thanks for all the help!
