Okay so I bought a Vulcan from a friend and having a little trouble. The thing is accurate as hell at 6p yards but anything past that it looses it's accuracy. It's a .22 and it's was shooting at 930 fps and I thought that was a little hot for the 18.13 cause of the spiraling. I adjusted the reg to about 120 bar and now it's shooting around 880 and still spiraling. Not as bad but still is. I'm not sure what to really do cause when my buddy had it it was shooting great out to 100 yards and he changed nothing... Ernest Rowe tuned it and put in a smooth twist barrel when he had it... just need some thoughts on what to do with it.. my plan is to get it to shoot amazing again then sell it
