NOT THAT MUCH...
The Impulse is accurate, but at ranges of 40yards or more a good cocker, shocker with same paint and barrel is somewhat more accurate and will have fewer off shots. The difference can be questioned, but barrell and marker tests done at our local store have shown so. The Impulse have a tendency to have slightly wider spread than the two mentioned. I use my Impy all the time over my cocker, because it is much more quiet. But I sort of like the flight of balls from the cocker a little more. I'm not too big a fan of saying all guns shoot the same. This is not true.
A cheap gun will in many cases chrono more unevenly than a highend one. This results in reduced accuracy for sure since you rely on constant range when firing. My Impulse is very good in this category. I'm not sure how much the fullflow and solenoidoptmizer affect this, but it should be very good out of the box.
The Precision in the making og the gun will affect precision. For instance the bolt in the Impulse matches perfectly, so perfect that a little too much Superlube will slow down an negatively affect the cycle. This is not true for a Spyder.
Another important aspect of shooting consistent is how good you're marker is on the balls. Low pressure, careful cycle will affect the projectile in keeping its shape. A closed bolt mode sort of falls into this category aswell. It might also affect the consistency of the position the ball has to bolt when propelled.
The Excalibur and Shocker are markers that incorporate both the closed bolt and extremely low pressure and have very good accuracy at the longer ranges. Personally I'm a big fan of low pressure because of the noise issue. But with a bad paint to barrel match I think it might generate more unwanted spin as in air blasting past the ball. This will be tryed out in the near future, as of now it's in "hypothesia". Well enjoy your Impulse it's highend and shoots great with a triggerjob. Feel free to mail me at
