Re: Increased Power = Increased Accuracy?

could be as simple as pellet choice. what would have seamed good at 10m at 5.5fpe is now not acceptable at 11fpe. the harmonics of the barrel will have changed, plus pellet speed. try cleaning the barrel and test again. if you use a benchrest it will remove yourself from the equation. mpr at 12fpe i...

Re: How long can air cylinder remain charged

i would not leave one at full pressure. although it has been designed to work at that pressure, with a built in factor of safety, it is still in a higher stress state than if it were left at half pressure.

Re: Close range pellet accuracy

by what you have described it appears to be what is described as cross over. if your pellet goes to the left at close range, try to confirm by pushing the range beyond your zero. if the pellet goes to the right you have crossover. have you considered your trigger technique? follow through on the sco...

Re: sighting S510

the simple answer is that the center of the barrels bore line is lower than the center of the scopes bore line. you will find that the center of the scope tube to the center of the barrels bore will be close to the distance you have measured. the imaginary lines do cross at some point usually at the...

Re: Lead free

I tried various "green" pellets years ago and didn't find anything that would group at more than 15 yards. thanks for the info Tim.
