The sun is shinning and there I was enjoying my shooting. Was testing my rifle of a bench for group sizes then after one shot I get a loud pop/hiss from the barrel. Looks like a seal has gone in the reg as it will not hold any air . Bugger!!! Will be giving someone a ring later tonight to see if I can get it back to him for a look as it was serviced in Dec. Good job I am not doing any comps till end of May. Lets hope I can get it fixed for Tawd Vale GP.
