I shot my M60B a couple of days ago and found out my POI passed 50 yards and beyond were much lower than before. I checked the speed of the projectile and found out the velocity had dropped 32 fps to 888 fps from 920 fps in May.

After inputing the data into the Element Ballistic Calculator, I was able to find the new POA for the ranges I was shooting at. A few starlings got dropped.

Enjoyed.

@Firewalker. I have been shooting this gun since Feb of this year. I haven't adjusted the Reg or HS yet. I got great accuracy with the NSA 17.5gr slugs so I just left it as is.

@Dr.Kralenstein. I have been reading up with the discussion you guys had on these mods. Very interesting.

For a 22, I think it'll be way over kill. The ports are .250 on the valve.

I would say since you haven't adjusted anything, the reg has finally settled and/or the hammer spring has lost some energy. Could try a half turn in and see what happens.
