This project has been moving at a stately pace
There are finally some results on an airgun forum, my original bullet did not shoot as well as round balls out of the prototype Lothar Walther barrel. Modifiction 1 was to drill out the base of the bullet to make the bullet look like an airgun pellet, that did not improve accuracy much. Modification #2 was to machine the nose of the cast bullet to a point, that made a significant improvement in accuracy. Please follow the link to see photos and text of the development work - http://airgunadvice.net/viewtopic.php?t=12293
the guy named 220 Swift is the machinist doing the airgun development work.
In the last group pictured, note the vertical stringing, this is due to shot to shot velocity variation because of a small reservoir size. The standard air reservoir size for this airgun is 400 - 500 cc, the reservoir pictured is only 174 cc so when the gun is finalized it should give 8 - 10 consistent shots.
Now for the real question
, Mtngun - can you make me a mold with a pointy nose like the final iteration of the machined pellet?
Thanks for looking,
