So, I am tuning my MROD 177 after installing a Huma reg and lightweight Hill hammer, hammer spring and valve spring. I am shooting strings over different hammer spring settings and I shoot a couple of pellet weights at a particular hammer setting then turn it a quarter in and shoot a couple more magazines. For some reason, I decided to check that the hammer spring was where I thought it was and it wasn't. I reset the hammer, shoot a couple of magazines, back out the hammer and it is a quarter turn less than where I set it. Can the hammer spring adjuster be drifting?
The good news is, with the regulator set at 1500 psi, I am getting 100 shots per fill!
