Walther Listing soon - Walther CP88 Competition .177 Air Pistols

Pending description, coming soon.

This photograph was taken after more than 150 shots, to give the barrel a chance to lead-in. As you can see, the shots are scattered mainly to the right of the target and not all sixteen have even hit my 14cm square target. I tried a couple of other types of target pellet and all gave similar results. This is very disappointing – shooting pellets through a rifled barrel should give much tighter groups than this. Most of my airsoft and BB shooting replicas can do better than this! Both my previous PX4s were capable of 1 – 1½” groups at 6m, though they were high and to left of the aim point. But, this is also puzzling. You can actually see the pellets deflecting to the right as they leave the barrel. What’s going on here and, most importantly, can it be fixed?

Intermission – Improving the PX4

OK, so it’s time to find out what the problem is. I have read in other sites a suggestion that inaccuracy is caused by the front face of the outer plastic barrel interfering with the flight of the pellet. And, if you look closely, you can see that the inner and outer barrels aren’t quite concentric and that the lower part of the plastic barrel does seem to overlap with the bore of the inner metal barrel. I’m going to describe what I did to improve my PX4, but please do remember that if you do these things, you will void your warranty and you may even end up with a replica that won’t shoot properly or at all. So, don’t do any of this unless you are confident in your ability. You have been warned!
