I only shoot a Berretta 92FS Co2 pistol at targets so the lighter the pellet the better. I don't need hitting power. If they made a lighter pellet it would be great.
The annoying thing is the automatic punching which is activated by two sensors in the punch mouth. The paper rarely gets punched straight as there is not way to be sure you are pressing up against the back of the punch mouth before it fires off. I needs extending backstop guides, not the flimsy right margin guide. The punch mouth catches on the paper and is not smooth at all leading to more mis-punches especially with just a few or single sheets.
